Murder suspect kills self in front of mom, officer near Houston

KATY, TX -- A 25-year-old veteran has been identified by his family as the victim in a deadly shooting in Katy, Texas.

Deputies say the man was fatally shot around midnight in Katy right before his killer took his own life outside a Harris County Sheriff's Office substation.

The victim's family says they do not want to talk right now, but did share a little more about him.

His brother says the victim served in the Army, and leaves behind his five children. His family described him as a good man, and says they are devastated by his passing.

The man was shot and killed at a home off of Katy Briar Lane, near Morton Road and Madison Road.

Detectives say a 17-year-old man found out his girlfriend was cheating on him with the victim, and asked the couple to come over. The two did, going to Darian Mitchell's home.

That is when Mitchell says he watched his friend, the 17-year-old accused gunman, kill the man.

"When he shot him, his girlfriend started screaming and then he ran," Mitchell says. "And then he shot again, and then everyone started coming out and screaming."

The suspect killed himself early Sunday after his mother drove him there to surrender for the shooting.

Harris County sheriff's Sgt. Cedrick Collier said the shooting happened in front of the teenager's mother and a sheriff's sergeant. Collier said the sergeant was leaving the building just after 5 a.m. when he noticed a car parked with its headlights on and approached to see if the people inside needed help.

Collier said the woman told the sergeant that she was there to turn her son in for the shooting that happened earlier in the morning in Katy.

"His mom got out of the vehicle and stated that her son shot someone earlier that day and that he was a person of interest," Collier said.

He said the sergeant drew his weapon and asked the teen if it was true. Collier said the teen responded "yes," stepped behind the vehicle, pulled a gun and shot himself in the head. The teen was taken to a hospital, where he died.
