Police: Don't know how far Philly captives case will extend

More victims could emerge in a case involving three people suspected of locking four mentally disabled adults in the cramped sub-basement boiler room of a Philadelphia apartment building, the city's police commissioner said Tuesday.

"We don't know the extent of this," Charles Ramsey told CNN. "We do know it goes beyond the borders of Pennsylvania - at least Texas, Florida and Virginia, and we suspect other locations as well."

The case began over the weekend, when the four people were found locked in the room, with no food and only a bucket for a toilet, police said. The pitch-black, 15-foot-by-6-foot space houses what police described as a boiler used to heat the building. A penetrating stench of urine and feces still hung in the chamber days after the discovery.
