GREEN COVE SPRINGS, Fla. -- A jury has convicted 31-year-old Anthony Washington guilty of first-degree murder in the death of a former U.S. Navy Commander at an Orange Park hotel in February 2014.

Forty-four-year-old Alphonso Doss was found dead, allegedly strangled inside the Astoria Hotel.

Washington faces life in prison. He has yet to be sentenced.

Two others who will stand trial: 35-year-old Ronnie Wilson and the victim's estranged wife, 47-year-old Yolinda Doss.

He looked on inside the Clay County Courthouse, as prosecutor Bernie De La Rionda detailed the strained relationship between Alphonso and Yolinda, explaining that Washington was Yolinda's lover at the time.

"They thought they had committed the perfect murder," De La Rionda said during opening statements Tuesday.

De La Rionda claimed Doss was strangled inside the Astoria Hotel in Orange Park by Washington and another man as Yolinda served as a lookout.

The motive? Authorities have said Yolinda wanted to collect $600,000 in insurance money she would have gained in the event of her husband's death.

"After you've heard all the evidence, the state will have proven beyond a reasonable doubt that this defendant is guilty of murder in the first-degree, both premeditated and felony murder," said De La Rionda.
