Brackett is charged as an adult with first-degree felony murder, along with felony discharge of a firearm and obstructing justice for allegedly hiding a gun and getting rid of the shirt he was wearing during the alleged shooting.
Brackett and George were arguing in a home near 3700 South and 6800 West, when Brackett grabbed a loaded handgun from the front room of the home and fired at his stepfather, according to charging documents. When the bullet went over George's head, Brackett allegedly fired again, hitting the man in the head. He then filed several more shots at the man on the ground, charges state.
George died the next morning in a hospital.
Brackett is being held in the Salt Lake County jail, with bail set at $1 million.
Before the Sept. 13 shooting, Brackett had only one run-in with the law, according to juvenile court records.
Brackett was referred to a juvenile court May 2010 for shoplifting less than $299 worth of property.
