[Updated at 6:11 p.m. ET] Virginia State Police have identified Ross Truett Ashley, 22, as a man they say fatally shot a Virginia Tech police officer on Thursday before killing himself about 30 minutes later.
[Updated at 10:47 a.m. ET] The person that investigators believe fatally shot a Virginia Tech police officer on campus Thursday is not believed to have had any previous contact with the officer, Virginia State Police spokeswoman Corinne Geller told reporters Friday.
Virginia Tech Police Officer Deriek W. Crouse and another man were fatally shot with the same gun on campus Thursday, police said. Police say they believe the second man matched the description of the gunman that shot the officer.
Investigators are "very confident" they know the identity of the person they believe shot the officer, Virginia State Police spokeswoman Corinne Geller told reporters Friday. Authorities intend to reveal the person's identity after an official determination is made and the shooter's family is notified, Geller said.
The motive for Thursday's killing is still unknown, she said.
[Initial post, 9:15 a.m. ET] The suspected Virginia Tech shooter was not a student at the university, school spokesman Larry Hincker said Friday.
Hincker declined to provide any further detail on the identity of the alleged shooter, though Virginia State Police have scheduled a news conference for 10 a.m.
Ballistics evidence testing has officially linked Thursday's two fatal shootings on the Virginia Tech campus, state police said earlier Friday.

A Virginia Tech police officer was among two people killed Thursday on the school's campus, prompting a sweeping search and school-wide lockdown that lasted over four hours.
Around 4:30 p.m., the school in Blacksburg, Virginia, announced on its Twitter feed that "law enforcement agencies have determined there is no longer an active threat or need to secure in place. Resume normal activities."
Police said the incident started shortly after noon, when the police officer made a traffic stop in the Coliseum parking lot near McComas Hall. During that stop, a person who wasn't involved in the traffic stop approached and shot the officer, authorities said.
After witnesses told police that the shooter fled toward a nearby parking lot, an investigating officer saw a "suspicious person" alive in that lot. When the officer circled back to approach the person - described as a white male - that person was dead of a gunshot wound, police said.

News of a shooting incident at Virginia Tech today, in which two people - including a Virginia Tech police officer - were killed, brought out a spirited debate about violence in educational institutions, as well as gun use. Some people were critical of Virginia Tech, but many were supportive. Among these comments were several passionate notes from the Virginia Tech community, with scores Hokies and their families expressing sadness over the deaths and support for the school.
One student posted the following comment while waiting in lockdown.
Ryan: "I'm currently a student at Virginia Tech, and I am currently locked in Pamplin Hall which is near where the events have taken place. This school is an amazing place with an amazing community, and nothing could happen here that would convince me to go to a different school no matter what anyone says. I feel extremely safe at this school, and I couldn't imagine myself anywhere else. To everyone that is being disrespectful, I'm praying for you that you can recognize how tragic some of the events that have happened here are."
Students shared their feelings and fears with the community:
Carol: "I am a Hokie and will go for my Ph.D. to Blacksburg and I really feel we do not deserve this. My prayers with all the Blacksburg students." FULL POST
Federal Aviation Administrator Randy Babbitt resigned Tuesday, three days after he was arrested on suspicion of drunken driving near his suburban Washington home.
In a brief statement released to the press, Babbitt said he had submitted his resignation to his boss, Transportation Secretary Ray LaHood, and that LaHood had accepted it.
Babbitt, a former airline pilot, said serving as FAA administrator had been "the highlight of my professional career."
"But I am unwilling to let anything cast a shadow on the outstanding work done 24 hours a day, 7 days a week by my colleagues at the FAA," Babbitt said.
The statement made no mention of the arrest.
Earlier in the day, LaHood told reporters he was "disappointed" that he had learned about Babbitt's Saturday night arrest only after police in the city of Fairfax, Virginia, released a press release about the incident.FULL STORY
[Updated at 4:27 p.m. ET] An autistic boy whose disappearance in a Virginia park five days ago prompted a search with thousands of volunteers was found alive Friday afternoon at a nearby quarry, authorities said.
Robert Wood Jr., 8, was found lying down but alert in a creek bed at a quarry near the 80-acre North Anna Battlefield Park, Hanover County Sheriff David Hines told reporters at a news conference.
The boy was flown by helicopter to a hospital, where he was reunited with his family. Hines said he didn’t know Robert’s medical condition, but the boy appeared to be “in good shape.”
“Whenever a child goes missing, everyone wants to step up. And that’s happened today,” Hines said.
Robert had wandered from his father at the park on Sunday. Robert, his father, Robert's younger brother and his father’s girlfriend were hiking at the park, which is in Doswell, Virginia, according to CNN affiliate WTVR.
The child was found less than a mile from where he was last seen, Hines said.
Robert is autistic and does not speak, which complicated the search, according to WTVR.

“If you have your pet bring them with you. … No one should be staying in their homes in an endangered area because they feel like they can't bring their pets with them," Christie said.

Perdue then referenced reports of a bowl-shaped part of the low-lying coastline that is especially vulnerable to high waters.

“I think we have had a cultural shift in government because, working with hurricanes for about the last 10 to 12 years while I was in uniform, local governments and governors were reluctant to make that decision to evacuate because of the impact [of what would happen] if they evacuated people and the storm didn’t come," he said. "But the options of not evacuating people, with the warnings that we have now and the accuracy of prediction, (it) needs to be done,” Honoré said.

“For some folks this will be the most significant event perhaps in 20 years from a tropical system,” Rappaport said.
He said unlike typical storms that follow a similar trajectory and curve move toward the sea, Irene"s forecast track comes very close to the shore.
"That means all the weather that's usually, in this case, worst to the east will be much closer to the metropolitan areas this time around," Rappaport said, "and in fact will definitely hit the southern New England area and since there are strong winds, high surge right near the center of the storm, we'll see some of that along the East Coast as well."
[Updated 8:53 p.m.] “The core of the hurricane” was barreling toward the North Carolina coast Friday night, the National Weather Service said in a bulletin. “The hurricane is forecast to move near or over the Mid-Atlantic Coast Saturday night and move over southern New England on Sunday.”

Once we begin to feel the affects of the hurricane, everyone should stay off the streets as wires and trees may come down. Don't put yourself in harm's way and don't put our emergency personnel in a position that could have been avoided."

Residents should make certain they have supplies and enough food, water, batteries and necessary medications to last for a couple of days.
The worst of the storm is expected Saturday night into Sunday, Patrick said, and downed trees and power lines are expected. He urged residents to stay off the roads. If travel is a must, try to complete it Friday before the storm arrives, he said.
As for air travel, the governor said, as of now, Logan International Airport will remain open, but there will “undoubtedly” be service interruptions.
Patrick said he was aware that this is one of the last summer weekends and said boaters and swimmers should be cautious about riptides and strong currents.

An intensifying Hurricane Irene churned northwestward over the tropical waters of the Caribbean Tuesday and is projected to make landfall in the United States this weekend.
The five-day forecast map puts the storm on the Carolina coast by Saturday evening, although the National Hurricane Center said predictions this far out can be hundreds of miles off, meaning most of the southeast is potentially at risk.
"The Southeast coast of the U.S. will feel some impacts from this storm," meteorologist Wallace Hogsett said. "It's difficult to say whether that will be in terms of big waves or whether it's a more direct impact."
Emergency officials in Florida, Georgia and the Carolinas stepped up operations in preparation for the first dangerous storm to threaten the United States in three years.
Irene became a Category 2 hurricane Monday evening, with maximum sustained winds of 100 mph. The storm could strengthen to a Category 3, which would make it a major hurricane, forecasters said.
"The storm was already stronger than we were forecasting," said John Cangialosi, a specialist with the Miami-based hurricane center.
He said Irene, the first hurricane of the 2011 Atlantic season, could even approach Category 4 status as it gathers steam over tropical waters.FULL STORY

Three things you need to know today.
Amy Winehouse: An autopsy to determine what killed singer Amy Winehouse has been scheduled for Monday afternoon, Scotland Yard says.
"Inquiries continue into the circumstances of the death," police said Sunday. At this stage, the 27-year-old's death "is being treated as unexplained and there have been no arrests in connection with the incident," police said.
The singer, beloved for her talent but infamous for erratic public behavior, arrests and drug problems, was found dead at her apartment in London on Saturday, police and her publicist confirmed.
Winehouse's family said in a statement Sunday it "has been left bereft by the loss of Amy, a wonderful daughter, sister, niece. She leaves a gaping hole in our lives. We are coming together to remember her and we would appreciate some privacy and space at this terrible time."
Somalia famine: The Food and Agricultural Organization of the United Nations convenes an emergency meeting in Rome on Monday to address the famine on the Horn of Africa.
Last week, a unit of the U.N. agency declared a famine in two regions of southern Somalia and warned that famine conditions are expected to spread in the coming months.
Monday's meeting was organized by the French government. Representatives from governments and non-governmental organizations are expected to attend.
The goal of the meeting is to look at ways to combat famine and drought in several countries and not to solicit pledges of aid, according to the FAO's website.

This is the 15th year for the Renewal and Remembrance event at the cemetery. The work to be performed is estimated at $250,000 in value, which will bring the total 15-year contribution to more than $2 million, according to the organizers.
When the state of the economy is discussed, it is sometimes analyzed solely from a macro level. But when it's broken down to the micro level, it can be seen how much the economic downturn has affected individual states, cities and small towns.
Manassas, Virginia, is one such town. But city officials say mindful budgeting and wise spending have allowed them to stay one step ahead.
"I would say that Manassas is in that lean and mean area," said Harry "Hal" Parrish, mayor of Manassas. "We made some (budget) decisions about three years ago when we saw the downturn starting."
Nevertheless, revenue is always welcome, and Manassas officials are taking advantage of a major Civil War anniversary of which they can take full ownership. They are commemorating the 150-year anniversary of the Battle of Bull Run – the first major battle of the Civil War. The four-day event, which ends Sunday, offers everything from workshops and exhibits to parades and a re-enactment of the battle.
City officials are expecting up to 25,000 people to come to Manassas, and they are expecting them to be in a spending mood.
"Any time you have an influx of people, heritage and tourism – those kinds of people are going to spend money," said Parrish.
Manassas officials say those 25,000 tourists could result in a $25 million boost to their city's economy.
"I hope to bring in at least half of what I normally do for Christmas," said Christine Finnie, owner of Whimsical Galerie. "I have a lot of 150-year commemorative items. I have everything from T-shirts to the beautiful tapestry wall hangings exclusive to my shop, and I am hoping that will be a draw to bring people in for those items, but then also look around and see other things they might like."
The big draw this week is the battle re-enactment. Thousands of people are expected to attend despite record-setting heat.
Four passengers aboard a commercial tour bus died and an undetermined number others were injured early Tuesday when the vehicle overturned on I-95 in Caroline County, Virginia, according to state police.
The bus ran off the right side of the road and overturned about a quarter-mile from the Carmel Church exit, according to Corinne Geller, public relations manager for the Virginia State Police.
Injured passengers were being taken to hospitals in Fredericksburg and Richmond, Virginia, Geller said.
Police have not named the tour company or the itinerary.
The accident happened before 5 a.m. Tuesday morning. As of 7:30 a.m., state police had closed the northbound lanes of the interstate while accident investigators examine the scene, she said.
The northbound lanes were expected to remain closed until mid-morning, according to police. Southbound lanes were not affected, Geller said.
The brood is back, and it's gonna be noisy.
Trees, posts, walls and other vertical surfaces throughout the American South are being covered this spring with billions of periodical cicadas: red-eyed insects that emerge, like Chicago Cubs fans' pennant hopes, for a few weeks just once every 13 years.
The bugs are perfectly harmless to humans, unless you count annoyance caused by the remarkable amount of noise the love-starved little critters make. The male cicada's mating call has been compared to a circular saw, only more shrill - and that's just the way the lady cicadas like it. FULL POST

Biologists believe a bald eagle that was a star of a popular Virginia eagle-watching webcam was killed Tuesday morning, struck by an airplane that was landing at Norfolk International Airport.
A U.S. Airways jet’s landing gear struck and killed a bald eagle as the plane was trying to land, airport official Robert Bowen said. One of the plane's fairings was damaged, but none of the 21 people aboard was hurt.
The eagle, biologists believe, was part of a nesting pair that has been at the nearby Norfolk Botanical Garden since 2003, and was the mother of three chicks that are featured on the garden’s Eagle Cam.
"We are fairly certain that this is the Norfolk Botanical Garden female eagle due to her physical characteristics, size and the fact that she has not been seen at the nest since the strike," said Stephen Living, biologist with the Virginia Department of Game and Inland Fisheries, and Reese Lukei of the Center for Conservation Biology, said in a written statement Tuesday.
Thousands of bird strikes are reported to the Federal Aviation Administration annually, and even strikes involving the formerly endangered bald eagle aren't unheard of. A different eagle was struck at the Norfolk airport two weeks ago, Bowen said. And 136 bald eagles were reported struck at U.S. airports from 1990 though March 2011, though that might be an undercount because the reports are voluntary and because it's not always clear what kind of bird was struck, according to the FAA Wildlife Strike Database.
