William Enman, the admitted killer who walked away from a Camden County psychiatric hospital Sunday afternoon, was found today - on the grounds of the hospital.

It was not immediately clear where Enman spent the last two days, but authorities said he left the Ancora Psychiatric Hospital in Winslow Township on Sunday with a backpack full of "camping and survivalist equipment."

Police searched the area around the hospital extensively, using infrared devices and a state police helicopter.

The search even extended to Canada because, authorities said, Enman bought a piece of property in Nova Scotia.

In the end, a New Jersey State Police detective, working with a U.S. Marshal's task force, found Enman in a wooded area of Ancora's 80-acre campus. He was captured about 2:30 p.m.

Enman, 65, has been hospitalized since 1975, when he was found not guilty by reason of insanity in two homicides.

Enman, a former Marine diagnosed with paranoid schizophrenia, admitted to killing his former roommate, Peter LeSeur, and LeSeur's 4-year-old son, Eric. Enman admitted to beating them to death with a baseball bat.

He has escaped from hospitals two other times.

Enman disappeared Sunday afternoon while he was supposed to be taking a scheduled, 50-minute unsupervised walk.

Typically, in cases of defendants deemed not guilty by reason of insanity, a judge meets with a patient's "treatment team" and decides what privileges that patient deserves, said Ellen Lovejoy, a human services spokeswoman.

Enman last met with a judge to review his status in August of last year. He was supposed to meet with a judge again on Thursday, authorities said.

At some point, a Morris County judge gave Enman permission to walk the 80-acre Ancora campus without an escort. Lovejoy did not know how long Enman had enjoyed that privilege.

Although Ancora, a 709-bed hospital, hosts some criminally insane inmates, the "vast majority" of the patients have been committed through proceedings in civil court, Lovejoy said.

There is a chain-link fence, about eight foot, around the hospital, but the grounds are not secured like a prison.
