Two men in town for a bachelor party and a local man driving through a parking lot were killed in Monday morning’s shooting outside a resort and casino in Reno, Nevada, police said.

Justin Aguila and Andrew Canepa, both 33 years old and residents of Ventura County, were in Reno with several friends to celebrate a bachelor party. They were on their way home Monday morning, waiting for a ride to the airport in the valet area near the main entrance of the Grand Sierra Resort, when the gunman shot them from behind, police said.

Authorities say two of the three people killed in a shooting outside the largest casino in Reno, Nevada, were 23-year-old men in town celebrating a bachelor party.
