Four people were killed in a murder-suicide inside a Texas home, authorities said.
Officers responded to a home in Houston around 3 a.m. after a woman called 911 saying she had been shot, Harris County Sheriff Ed Gonzalez said during a press conference.
When officers arrived, the suspect, a 49-year-old man, opened fire.
A SWAT team also responded at the scene and tried to negotiate with the suspect for hours to no avail, according to the sheriff.
Officers managed to break in when they heard a final gunshot and discovered the four bodies around 7 a.m.
Authorities believe the suspect was in a relationship with the woman who called 911.
He allegedly gunned her down as well as another man and woman — possibly the woman’s children, according to Gonzales.
A motive for the shootings is being investigated.
