According to WFAA, 23-year-old Sean Garrison, 18-year-old Tyee Garrison and their 17-year-old brother are currently awaiting arraignment on the charges and are in police custody.
Authorities executed an arrest warrant for the brothers on Wednesday following the Sept. 18 death of 18-year-old Xavier Olesko.
The report notes that Olesko was fatally shot in the chest around 8:40 p.m. outside a home in the 8100 block of Tumbleweed Trail.

Detectives believe that the eldest Garrison brother and Olesko knew each other and had planned to meet. However, the brothers had planned on robbing Olesko during the meeting, where things apparently went bad and Olesko was shot and killed.
According to the Star-Telegram, Olesko was a popular Western High School senior whose death left friends and loved ones heartbroken.
Investigators believe that Olesko was temporarily living with friends at the Tumbleweed Trail residence and was in the backyard with some of them before the shooting.
Witnesses told the police that the teen went to the front of the residence to meet with someone when they heard a gunshot. When Olesko’s friends ran out front, they found the 18-year-old lying on the ground not moving. One of the witnesses called 911.
Witnesses told police that they did not see anyone leave the area on foot or in a vehicle, but eventually the suspects were narrowed down to the Garrison brothers. Police originally responded to the call as a possible suicide.
Each brother is currently being held on $200,000 bond.
The Star-Telegram notes in another report that at least two of the three brothers have been in trouble with the law before because of violent crimes.
Just in July, Sean Garrison was indicted on a charge of injury to a child in Fort Worth, and he was accused of injuring a girl younger than 15 back in March, the report notes. The indictment indicates that Garrison harmed the child by pushing her against a hard object or surface, hitting her and/or biting her.
The case is still pending, but Garrison was released from jail on $5,000 bond.
His little brother Tyee Garrison has been convicted twice of assault causing bodily injury in 2016, both charges being a Class A misdemeanor.
From the Star-Telegram:
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.
It is currently unclear if the brothers have retained an attorney in this latest case.
