Two people were killed in a shooting at a Halloween house party near Grand Junction on Friday night, according to the Mesa County Sheriff’s Office.

Deputies responded to multiple 911 calls about a shooting at a home in the 400 block of Cottonwood Lake Drive in Clifton at 11:50 p.m., the sheriff’s office said in a news release. Clifton is an unincorporated community east of Grand Junction.

Deputies found two victims with serious injuries and started CPR, but both were pronounced dead at the hospital about an hour later.

Investigators believe an “incident” caused one or more people to start shooting during the party, sheriff’s officials said. The shooting is being investigated as a double homicide.

The names of the victims will be released by the Mesa County Coroner’s Office.
