The preliminary hearing of the 51-year-old Weston, a paroled killer charged with kidnapping and abusing four rail-thin mentally disabled adults to get their government benefit checks, was held Monday Dec. 19, 2011 in Philadelphia. Her daughter, boyfriend and friend also have been charged in the case.

PHILADELPHIA — A mentally disabled man says he didn't see his government benefit checks for 10 years after he began living with a woman who is now charged in a widespread fraud and abuse scheme.

Thirty-one-year-old Edwin Sanabria also testified Monday that he was once kept in a closet that was nailed shut by Linda Weston.

Sanabria testified at Weston's preliminary hearing. He is one of four mentally disabled adults who were discovered locked in a squalid basement in Philadelphia in October.

Weston is accused of kidnapping and abusing the victims to get their benefit money. Prosecutors suspect the 51-year-old paroled killer had perhaps dozens of adult and child victims.

Sanabria says Weston took him to a government office in 2001 to sign paperwork. He says he never again saw his $674 monthly checks.
