PHILADELPHIA (AP) — A woman convicted of fatally shooting two co-workers at a Philadelphia food plant has been formally sentenced to life in prison.
Earlier this month, a judge found Yvonne Hiller guilty of two counts of first-degree murder and other counts in the deaths of 47-year-old Tanya Wilson and 36-year-old LaTonya Brown.
First-degree murder carries a mandatory sentence of life in prison without parole. On Monday, Hiller was sentenced to two consecutive life terms.
Hiller had been suspended the evening of Sept. 9, 2010, the night of the shootings, after making violent, profanity-laced threats against co-workers. But she returned from her car minutes later with a loaded .357 Magnum.
Defense attorneys had argued that Hiller was motivated by a deeply held belief that her co-workers were poisoning her.
