A Texas man opened fire at a youth soccer tournament and killed his ex-wife and her boyfriend on Sunday, then later killed himself. 

The suspect arrived at the Harris County tournament around 10 a.m. and argued with his ex-wife in the parking lot near Almeda Park, according to witnesses. As the argument intensified, the suspect shot the woman and her boyfriend, then fled the scene in a vehicle. 

The ex-wife, 28, who was pregnant, was transported to hospital, where she succumbed to her injuries and was pronounced dead. The boyfriend, 35, was pronounced dead at the scene, the Harris County Sheriff’s Office announced in a statement on Twitter.
