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.

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.
