Dallas police have arrested a man who they said went on a shooting spree, killing four and wounding four others.

The shootings began at homes in Dallas and DeSoto, Texas when suspect Erbie Bowser, 44, attempted to kill his former girlfriend and ex-wife on Aug. 7.

According to the Associated Press, the rampage began about 10:30 p.m. in Dallas at a home in the 7100 block of Long Canyon Trail, where Bowser killed Toya Smith, 43, and her daughter, Tasmia Allen, 17. Smith’s 14-year-old son and 17-year old family friend were injured in the incident, but were taken to a local hospital for treatment.

According to authorities, Bowser then traveled 10 miles southwest of Dallas to DeSoto to the home of his estranged wife, Zina Bowser, where he tossed a grenade into the living room prior to shooting and killing her and another woman, who has not been identified. Before running out of bullets, Bowser shot two boys, ages 11 and 13, according to officials.

Bowser, was a male NBA cheerleader for the Dallas Mavericks and former U.S. Army soldier. He served in the military for nine years, as a staff sergeant.

The Dallas Mavericks in a brief statement said they, “are not planning on making a statement regarding Erbie Bowser’s past association with the Mavs.”

Bowser had several previous run-ins with the law. In 2011 he was arrested for aggravated assault with a deadly weapon. Zina Bowser filed for divorce in 2011, following a protective order issued by the associate judge presiding over their divorce, according to The Dallas Morning News.

Police were able to apprehend Bowser and charged him with capital murder in the shootings.
