Nine people are dead after a man opened fire on a football watching party at a Plano, TX, home Sunday night. The unidentified suspect was shot and killed by an officer who arrived at the home just after 8 p.m.

The officer found bodies in the yard and heard shots coming from inside the house.

"[He] made entry inside the house, confronted the suspect, ultimately shooting and killing him," Plano PD Officer David Tilley said.

The Texas Rangers are assisting with the investigation, especially since it involved an officer, who Plano PD Chief Gregory Rushin says went into the house by himself and stopped the shooter before waiting for backup. "When something like this occurs, you can't wait, you have to go in, cause seconds matter," Chief Rushin said.

Debbie Lane told WFAA that her daughter, 27-year-old Meredith Lane, owned the home and had recently filed for divorce from her husband. She says he showed up at her daughter's home and opened fire.

Lane says her daughter, a Georgia native, hosted an Atlanta Falcons watch party, and the group was about to watch the Cowboys game.
