WICHITA FALLS, TX --Police have arrested George Coty Wayman in the shooting death of his stepson this week.
Wayman, 18, is charged in the murder of 3-year-old Dominic Castro.
According to officials in Wichita Walls, witnesses initially claimed the gun accidentally discharged as the boy was jumping on a bed.
KFDX reports that those witnesses later recanted, saying Wayman threatened the boy with the gun, telling him to stop jumping on the bed.
Wayman then allegedly shot the boy in the head.
Officials say physical evidence corroborates the witness accounts.
