BAY MINETTE, Ala.—Nichole Bryars Kelsay pleaded guilty Sept. 12 to a charge of conspiracy to commit murder for her part in the 2004 slaying of a gay teenager and was sentenced to 20 years in prison.

Kelsay, 21, had no comment at sentencing, Baldwin County District Attorney Judy Newcomb said.

The victim, Scotty Joe Weaver, 18, had been friends with Kelsay since first grade and at one point had asked her to marry him. Kelsay’s boyfriend, Christopher Ryan Gaines, objected.

The couple plotted Weaver’s death, according to Baldwin County prosecutors, enlisting Robert Holly Lofton Porter in the murder scheme. Porter told authorities he didn’t like Weaver because of his homosexuality.

Prosecutors allege Weaver was robbed of about $80, strangled and beaten inside his Bay Minette trailer in mid-July 2004. His burned and mutilated body was found in a field a few miles away.

Gaines, now 23, pleaded guilty to capital murder and received life without parole. Porter, 21, pleaded guilty to intentional murder and first-degree robbery and was ordered to serve two consecutive life sentences.
