On Sunday evening, a tragic shooting in a Glendale, Arizona restaurant resulted in three fatalities and left five others injured, according to officials.

The incident occurred at approximately 7:45 p.m. inside El Camaron Gigante Mariscos & Steakhouse, reported Officer Moroni Mendez of the Glendale Police Department at the location.

“There were many individuals present,” Mendez stated. “A lot of people who were there for an event. We’re asking anyone with information to step forward and share it with us because, as we mentioned, three lives were lost. It’s important that we conduct a thorough investigation to honor the victims properly.”

Police did not immediately provide details about the three victims killed in the shooting. Mendez said the other five victims were injured by gunshots or shrapnel.

“There are quite a few people detained, and we’re trying to investigate whether they’re suspects, victims, witnesses, investigative leads,” the officer said. “There are multiple people that our officers and detectives are speaking to.”

Lupe Rodriguez told KPHO-TV that he heard people screaming during the aftermath of the shooting.

“There was a man on the ground, and it didn’t look like he made it,” Rodriguez said. “His father – what I think is his father – was yelling out his name. It was pretty bad.”
