Police were searching for leads after an aspiring rapper was shot dead in a posh suite at a Las Vegas resort.
Police say Evan Plunkett, who performed under the name "Hollywood Will," was shot in the chest after a fight erupted between him and three other men during a party in the Palms Casino Resort's Fantasy Tower.
Others involved in the Thursday night fight fled the suite before police arrived, and no arrests have been made, investigators said. About 40 to 50 people attended the party.
A music video was being filmed in the suite when an argument broke out between Plunkett, 25, and the other men, according to friends.
"There was an altercation. He was trying to get everybody to stop fighting. Apparently, he took a shot to the chest," Barbara Combs, a neighbour and friend of Plunkett's mother, told KVVU-TV.
He was taken to a hospital, where he was pronounced dead.
Plunkett's brother suffered multiple broken bones after trying to pull the rapper out of the fight, Ms Combs said.
The Palms is home to some of the most extravagant party suites in Las Vegas, including a 9,000-square-foot Sky Villa that rents for 40,000 dollars (£23,800) a night and a Hardwood Suite that features a private basketball court.
Randi Flippin, a friend of the victim, said she's surprised the suspects were still at large.
"It just amazes me that nobody knows anything," she told the Las Vegas Sun.
"There is no suspect at all. There were only 50 people in the room and nobody knows anything? That's insane to me."
Plunkett pursued his love of rap music after returning to Las Vegas from a stint as an aviation mechanic for the Marines, according to friends.
