Two of the three brothers accused in the killing of a Fort Worth teenager in White Settlement have faced prior criminal charges, including a pending felony charge of injury to a child.

Sean Garrison, 23, Tyee Garrison, 18, and Kyle Garrison, 17, all from White Settlement, were arrested Wednesday in the fatal shooting of Xavier Olesko, 18, on Sept. 18 in front of a home in the 8100 block of Tumbleweed Trail.

Sean Garrison was indicted in July on a charge of injury to a child in Fort Worth. He is accused of injuring a girl younger than 15 in March, according to Tarrant County court records.

The indictment says Garrison injured the girl by pushing her against a hard object or surface, striking her and/or biting her.

Garrison was arrested in that case in May and was released from jail on $5,000 bond. The case is pending.

Tyee Garrison was convicted twice in 2016 of assault causing bodily injury, a Class A misdemeanor, according to court records. Both incidents happened in Watauga.

In the first case, which was initially filed as a robbery, he was accused of assaulting a man by punching him, hitting him with a chain wrapped around his fist and/or scratching him, according to a criminal complaint.

He received deferred adjudication, meaning it wouldn’t have gone on his record, but the sentence was reinstated after the second assault charge and he received 10 days in jail.

He was also convicted in July of possessing less than 2 ounces of marijuana, a Class B misdemeanor, and sentenced to two days in jail.

In the White Settlement case, all three brothers face capital murder charges. The arrest warrant affidavit has been sealed by a magistrate judge.

Detectives believe that Olesko and Sean Garrison were acquaintances and planned to meet on the evening of Sept. 18, according to a police news release.

Detectives believe that Sean, along with his brothers Kyle and Tyee, met with Olesko in front of the Tumbleweed Trail home with plans to rob him. During the encounter Olesko was shot.

Police found Olesko’s body in the driveway while responding to a possible suicide call.

Investigators believe that Olesko was temporarily living at the residence with friends and was in the back yard with some of them just before he was fatally wounded.

Witnesses told police that Olesko went around to the front of the residence to meet with someone. Then they heard a gunshot. Olesko’s friends said they ran to the front of the residence and saw Olesko lying motionless on the ground. One of the witnesses called 911.

Witnesses also told police they did not see anyone leave the area either on foot or in a vehicle.

Olesko had been a senior at Fort Worth Western Hills High School, where he played football. He had also attended nearby Brewer High School.

Police said other arrests may follow.

The Garrison brothers were arraigned Thursday and were being held in lieu of $200,000 bail at the White Settlement Jail. It was unclear if they had retained an attorney.

Their brother Bryan Garrison, 20, was sentenced to 50 years in prison in June after he was convicted of continuous sexual abuse of a child under the age of 14, according to court records.

The victim in the case was the Garrisons’ next-door neighbor, court documents said. At the time the brothers lived in Watauga with their mother and grandparents, but their mother “left them alone often and was a drunk and a bad mom,” according to documents filed by prosecutors.

The victim’s family later moved out of Watauga “to get away from the Garrisons,” the documents said.

Bryan Garrison’s attorney, Blake Burns, filed a motion in August seeking a new trial.

The Garrisons’ mother could not be reached for comment. An aunt, Heather Garrison, said the brothers’ father died in 2003.

“I found out [about the arrests] like everybody else — on the news,” Heather Garrison said. “All I can say is I pray for Xavier’s family along with my own.”

Fort Worth Police and the Tarrant County Sheriff's Office are looking for these 10 fugitives. Crime Stoppers will pay up to $1,000 for information leading to an arrest. Call 817-469-8477.
