Ex-NFL player Aqib Talib's brother surrenders in fatal shooting of youth coach at Texas football game

Former NFL cornerback Aqib Talib’s brother turned himself in to authorities in connection with a shooting at a Texas football game that left a coach dead, according to police and officials with a youth athletic league.

Police in Lancaster, in Dallas County, identified the suspect as Yaqub Talib, who voluntarily turned himself in at the Dallas County Jail on Monday.

Officers were dispatched to Lancaster Community Park around 8:50 p.m. Saturday after multiple calls.

Officers were told that there had been a disagreement among coaching staff members and the officiating crew, police said.

"During the disagreement, the opposing coach staff were involved in a physical altercation and one of the individuals involved in the altercation discharged a firearm striking one adult male," the police department said.

The victim was taken to a hospital, where he was pronounced dead later, the police department said.

TMZ reported that Aqib Talib, who played for the Tampa Bay Buccaneers, New England Patriots, Denver Broncos and Los Angeles Rams across 12 NFL seasons, was also at the scene. NBC News was not immediately able to confirm the reporting.

“Aqib was present when this unfortunate incident occurred and is very distraught and devastated over this terrible loss of life," an attorney for the former NFL player told TMZ.

“He would like to convey his condolences to the family of the victim and to everyone who witnessed this unfortunate tragedy,” the attorney reportedly said.

The victim was later identified as coach Mike Hickmon, according to NBC Dallas-Fort Worth.

Sharing condolences for Hickmon’s family on its Facebook page, TexaSports, a youth athletic league, said: “Tonight we lost a great father, son, husband and coach."

Hickmon “was coaching his son and team today at a sporting event somewhere in Dallas when his life was taken by a coward,” the post said. “We pray for the Family and our community at this crazy time in youth sports.”

A spokesperson for TexaSports told NBC Dallas-Fort Worth that Hickmon had been coaching in the league for years. However, the spokesperson said Saturday’s event was hosted by a different organization.

Pastor Keith Hall, who told NBC Dallas-Fort Worth that Hickmon was a member at his church, said he called Hickmon's wife after Saturday's incident. “She said, ‘Pastor he didn’t make it. He didn’t make it.’ And she was just heartbroken, and all the air was sucked out of us," Hall said.

Hall said Hickmon was active in their church, Grace Temple Fellowship, and was passionate about coaching youth football.

“People gravitated to him. They loved him, and they called him ‘coach.’ He took time with them,” Hall told NBC Dallas-Fort Worth. “That’s just the type of person he was.”
