A suspected serial killer has killed for the last time.
Authorities say Israel Keyes, who was arrested and charged in the killing of an Alaskan barista, killed himself while in custody.
Before committing suicide on Sunday, Keyes confessed to at least seven other slayings, according to the FBI field office in Anchorage, Alaska, which on Monday asked for the public's help with tracing Keyes' travels over the years in the hopes of identifying any additional victims.
He crisscrossed the country, and authorities may never know how many he killed.
"Based upon investigation conducted following his arrest in March 2012, Israel Keyes is believed to have committed multiple kidnappings and murders across the country between 2001 and March 2012," the office said in a statement. "Keyes described significant planning and preparation for his murders, reflecting a meticulous and organized approach to his crimes."
John McAfee, the Internet security pioneer wanted for questioning in the killing of a neighbor in Belize, is now in Guatemala City, said Telesforo Guerra, the former attorney general of Guatemala.
McAfee has hired Guerra as his attorney, Guerra told CNN en Espanol on Tuesday.
Belize authorities want to talk to McAfee about the November 11 shooting death of American businessman Gregory Faull, 52, who was found dead in his home near San Pedro, on the Caribbean island of Ambergris Caye.
On his website, McAfee commented about his relocation: "I apologize for all of the misdirections over the past few days. It was not easy to exit Belize and required many supporters in many countries.
If insanity is doing the same thing repeatedly and expecting a different result, then continuing negotiations on a deal to avoid the fiscal cliff might amount to little more than crazy talk.
The same players are arguing about the same issue - taxes - in a repeat of budget showdowns of the past two years that failed to reach a comprehensive agreement.
President Barack Obama's re-election in November, coupled with a perceived desire by congressional leaders to shed their reputation of dysfunction, raised expectations for a possible deal.
However, with four weeks to go until the automatic tax hikes and spending cuts of the fiscal cliff get triggered, the two sides remain unable to resolve a central issue - whether wealthy Americans should pay more taxes than they do now.
The NATO alliance weighed in on the Syrian crisis Tuesday, warning the Bashar al-Assad regime about using chemical weapons and mulling a Turkish request for Patriot missiles to defend its borders.
NATO's secretary-general echoed warnings from U.S. President Barack Obama that the Syrian government may be toying with the idea of using chemical weapons to crush the 21-month rebellion.
"The Syrian stockpiles of chemical weapons are a matter of great concern," Anders Fogh Rasmussen told reporters.
"We know that Syria possesses missiles. We know they have chemical weapons and, of course, they also have to be included in our calculations. And this is also the reason why it is a matter of urgency to ensure effective defense and protection of our ally Turkey," he said.
"Let me add to this that the possible use of chemical weapons would be completely unacceptable for the whole international community, and if anybody resorts to these terrible weapons I would expect an immediate reaction from the international community."
The Syrian Foreign Ministry denied that the country has any plans to use chemical weapons, state TV has reported. The government likewise has repeatedly stressed it will not use such weapons, if they exist, against its people under any circumstances.
But U.S. officials say "worrying signs" suggest otherwise.

Iran's navy has captured what it says is a U.S. drone after it entered Iranian airspace over the Persian Gulf.
However, a U.S. defense official, who could not be named because the official was not authorized to speak to the media, told CNN that whatever the Iranians claim to have, it is not an actively operating U.S. Navy drone.
"The U.S. Navy has fully accounted for all unmanned air vehicles (UAV) operating in the Middle East region. Our operations in the Gulf are confined to internationally recognized water and air space," the source said. The internationally recognized territorial limit is 12 nautical miles off the coast.
It is not yet clear whether any other branch of the U.S. military or government might have been operating a drone in the area.
