PITTSBURGH — Prosecutors have withdrawn a homicide charge against a woman accused of having asked a co-worker to beat up a former lover who was later shot to death.

Jamie Parker, 30, of Wilkinsburg was charged last month in Allegheny County in the Oct. 14 slaying of Leonard Butler, 44. Authorities alleged she was angry after learning Butler had been released from jail without telling her and after finding another woman at his home.

Prosecutors withdrew the homicide charge Friday over what a spokesman called “evidentiary reasons.” Parker remains charged with conspiring to commit robbery. Two men face homicide charges.

Defense attorney Blaine Jones said Parker cared for Butler and was “distraught” over what happened to him.
