The Associated Press reports Yvonne Hiller, the suspended worker charged with killing two colleagues at a Philadelphia food plant earlier this year, told police she thought co-workers had been spraying her with deer urine.
Hiller has been ordered to stand trial in the September shooting spree at a Kraft Foods plant. The ruling comes after a court hearing Tuesday, when a homicide detective read a statement Hiller gave police after her arrest.
According to the statement, the 43-year-old Hiller thought she was being pranked by co-workers. She said she initially planned to go home after being suspended over a confrontation with her alleged tormentors. But police say she instead grabbed a gun and returned to the plant, killing two and injuring one.
