SAN DIEGO — Police shot and killed a 49-year-old man suspected of shooting seven people Sunday at a birthday pool party in an apartment complex near the University of California, San Diego, authorities said.

Authorities said the suspect, a white man identified as Peter Selis, shot four black women, two black men and one Latino man.

Rikky Galiendes, 27, heard gunshots around 6 p.m.and went to look outside his sixth-story apartment when he spotted a man bleeding and running near the pool below. Galiendes told The Associated Press that he called out to ask if the man needed help when his roommate grabbed him, yanked him down and then pointed toward a man sitting in a chair with a gun.

“When we looked over the balcony, he was just sitting down with a gun on his lap,” Galiendes said. “He was calm, you know. I mean from my perspective, the guy was ready to do whatever he was going to do. He shot at people having a good time and having a party.”

Galiendes and his roommate ran back inside and called police. They stayed indoors until neighbors yelled that it was safe to come out.

One woman who was shot died, several victims were in surgery and others were still critical late Sunday, Chief Shelley Zimmerman said. An additional man was taken to the hospital after he broke his arm while fleeing.

Three officers shot the suspect after he pointed a large-caliber hand gun at them, Zimmerman said.
