Jack Junior Montgomery, 31, of Tampa, Florida was charged Sunday with a first-degree murder for killing his stepson, age 7, Brice Russell.

While the mother left her boy and her other three sons with Montgomery to work a double shift, Montgomery repeatedly punched and kicked the 7-year-old when he got out of bed to get a cookie, Assistant State Attorney Matthew Smith told the court.

Not only did Montgomery take the matters to choose to physically discipline himself, by repeatedly punching and throwing him on the ground, but started “threatening bodily harm to the brothers if they did not partake and equally discipline him,” Smith Said.

The boy’s told investigators they were forced to watch Montgomery hit him and were threatened if they did not join in.

“Montgomery picked him up and flung him as described by the other brothers, helicopter across the hotel room into what’s kind of a cabinet, where he hit head first. And ultimately caused his brain to bleed,” Smith said.

An employee of the hotel heard loud shouting, where a man was yelling “beat the kid” and “push the kid over there” and called the police, WTVT reported citing the affidavit.

At around 1:00 a.m. on Saturday, the HCSO responded to conduct a welfare search and a HSCO deputy met with a man who identified himself as “Jack” and advised him that the loud noise was him playing his music loudly. He told the deputy he was in the room with his children and opened the door just enough for the deputy to see the children sleeping in the back of the room.

The deputy did not enter the room and cleared the call with no further investigation, according to the arrest affidavit.

The deputies responded to same motel room after 10:50 a.m., because later that day, Montogomery called 911 to report his stepson would not wake up.

Fire rescue crews responded to find Brice lying down in the bed. And was pronounced deceased at 10:59 a.m.

The Medical Examiner’s Office determined the result of the victim’s death was of homicidal violence.

Montgomery was arrested on Sunday and since has been charged with aggravated child abuse and felony first-degree murder. He was booked in the Orient Road Jail.
