Update:
NEW CASTLE, Pa. (AP) -- The clothing of an 11-year-old accused of killing his father's pregnant fiance had gunshot residue on it, a state trooper testified Tuesday at his preliminary hearing, where the boy was held for trial.
Trooper Troy Scott Steinheiser testified the clothing was taken from Jordan Brown the evening of Feb. 20, the day Kenzie Marie Houk, 26, was found dead in the bedroom of the farmhouse in Wampum, where she lived with her two daughters, Brown and his father, Christopher Brown.
Tests revealed the residue, Steinheiser testified. Another trooper, Sgt. Kenneth Markilinski, testified that he found a 20-gauge shotgun in Brown's upstairs bedroom and it smelled as though it had recently been fired.
