Officers said the shooting happened at a 4-year-old's birthday party around 6:30 p.m. at a home on Majestic Street.

We're told the suspect grabbed a high-powered rifle after an argument broke out and opened fire, shooting three people.

One of the victims, a 60-year-old man died at the scene. His 20-year-old son, who was also shot, was taken to Ben Taub Hospital. Officers have not released details on the third victim.
