Authorities are investigating the sinking of a yacht owned by Las Vegas entertainer Wayne Newton at a US marina.
National Park Service spokeswoman Christie Vanover says the 20m vessel sank stern-first in 14m of water while it was in a slip at the Temple Bar marina, on the Arizona side of the Colorado River reservoir, about 128km east of Las Vegas.
Vanover says no one was on the boat, and no injuries were reported.
Newton's sister-in-law, Tricia McCrone, confirms that the 1996 Skipperliner named Rendezvous belongs to Newton.
McCrone says Newton and his wife were vacationing when the boat sank on Friday.
