OK:Armed self defense by felon at his home

Walker said witnesses report that the victim showed up at Lyke's house with a gun, and the two men exchanged gunfire.

"We have witnesses saying that's what occurred, so we can't in good faith charge him with murder," he said.

Lyke was arrested for possession of a firearm after former conviction of a felony. Authorities added other complaints from traffic violations earlier this month and a charge of knowingly concealing stolen property from JC Penny in December, 2012.
