HOUSTON (CBSDFW.COM/AP) — Police are investigating a believed domestic violence situation in Texas that left four people dead.

The adults were found inside a home in Houston after a man fired at police before turning a weapon on himself.

Officers went to a home on the city’s northeast around 3:15 a.m. after receiving a call reporting that a woman had been shot, Harris County Sheriff Ed Gonzalez said at a news conference. The officers were met with gunfire and a SWAT team from the sheriff’s office was then sent  to the home.

Gonzalez said the SWAT team was eventually able to negotiate with the man to enter the home, but as team members were going inside they heard “a final gunshot.” In the house, the officers found two dead women and two dead men, including a 49-year-old man who shot himself, he said.

Gonzalez said he believes the 49-year-old was the boyfriend of one of the women and that the other woman and man were her adult children. He also said one of the women who was ultimately shot is likely the person who called police. He did not identify any of them by name or give the ages of the other three.

The sheriff said the boyfriend appears to have been “the aggressor,” but he emphasized that investigators are not yet certain of how the shootings played out. He said multiple guns were found in the home and the 49-year-old told police he was injured before he shot himself.

Gonzalez said investigators believe everyone but that man had been shot before officers arrived. He said officers did not fire any shots and that no officers were wounded.

Sheriff’s deputies have not been called to the house before, according to Gonzalez.
