UNIONTOWN, Pa. - Authorities are searching for the ex-boyfriend of a woman found shot to death in her car after charging him with criminal homicide in her death.

Authorities say he should be considered armed and dangerous.

Pennsylvania State Police announced Wednesday that Walker has been charged with criminal homicide in the death of 36-year-old Mya Ann Grady, also of Uniontown, who was found shot in the head in her car along a western Pennsylvania highway on Saturday.

Pennsylvania State Police Trooper Stefani Lucas told 48 Hours' Crimesider that Walker is Grady's ex-boyfriend.

Grady, a mother of four, was found dead Saturday morning by PennDOT snow plow drivers along the berm of Route 40 on Summit Mountain. The highway leads from Uniontown up the mountain to Nemacolin Woodlands Resort, where Grady worked at the Lady Luck Casino.

A police affidavit alleges Grady was on her way to work when she was shot twice in the head through her driver's side window.

The affidavit says that police spoke with members of the victim's family who told them Grady had been romantically involved with Walker for about 7 years and had recently broken off the relationship.

The family members described Walker's relationship with the victim as turbulent and abusive, according to the affidavit.

Police subsequently interviewed Walker, who allegedly admitted to following Grady as she headed to work on Saturday. The affidavit says Walker told police he was present when the two gunshots were fired.

The affidavit also alleges a woman, whose identity is being withheld, called authorities and said that Walker told her on the day before the murder that he was planning to kill Grady.

Anyone with information on Walker's whereabouts is asked to contact the Pennsylvania State Police in Uniontown at (724)-439-7111.
