SPOKANE, Wash. -

The mother of murder suspect Joshua Tillery made a plea for her son to turn himself in Tuesday.

Spokane Police say a fight lead Tillery to shoot 33-year-old Devon Mack in the head last Friday.

Witnesses have said Tillery had a gun in his hand when the two men started fighting in the living room. Moments later the gun fired and Tillery ran from the home. He hasn't been seen since.

On Tuesday Tracey Tillery made an impassioned plea from California for her son to go to the police.

"Joshua this is mama. Please if there's a pastor or someone you really trust out there, call them, let them go with you. Turn yourself in, this is a horrible thing. I know you're scared and hurting. Dad and I will do whatever we have to do to get you help. Our hearts and our prayers go out to the (victim's) family," she said.

Witnesses said Tillery told them he didn't mean for the gun to go off, but then they saw him leave from the back of the home with a woman.

Police hope his unique tattoos will help someone point him out to authorities.

Considered dangerous, police are asking anyone with information on his whereabouts to call 9-1-1 immediately.
