One of three defendants accused of killing a teenager because he was gay has pleaded guilty to capital murder, prosecutors said. As required by state law, jurors will still hear testimony in an abbreviated trial and a judge can sentence Christopher Gaines, 22, to death or life in prison without parole. Gaines likely will get life in prison because of the plea deal he entered on Monday, prosecutors said.

Authorities have said Gaines and two others attacked Scotty Joe Weaver at his trailer in 2004.

Prosecutors said they beat, strangled and cut the 18-year-old before setting his body afire, and the extent of Weaver's injuries pointed to the attackers' distaste for his sexual orientation.

Gaines will not testify at the trial set to start May 7, but jurors will watch a video recording of his confession, defense attorney J. Clark Stankoski said. Lawyers have not said whether Gaines will testify against his two co-defendants, Robert Porter and Nichole Kelsay, who are scheduled to be tried separately later this year.

The slaying drew interest from gay rights groups, and hundreds of mourners attended a vigil for Weaver in Mobile after the killing. Anti-gay groups picketed outside the Crossroads Church of God, where Weaver's funeral was held.
