Man pleads no contest in slaying of his alleged molester!!

(CNN) -- A California man pleaded no contest to voluntary manslaughter with the use of a gun Tuesday in the shooting death of a man who he claimed sexually abused him as a teen, a prosecutor said.

The plea comes less than a week before Aaron Vargas' first-degree murder trial was supposed to start for the slaying of Darrell McNeill, a neighbor from his childhood and a family friend whom Vargas claims began molesting him when he was 11 years old.

Under the terms of a plea deal, Vargas, now 32, faces anywhere from probation to 10 years in prison for shooting the former Boy Scout leader and local businessman last year in his home in the Northern California community of Fort Bragg.

Lawyers will return to court April 20 to place a statement of facts on the record before Judge Ronald Brown decides on the final sentence. "There's some relief that we know we won't lose him for the rest of his life, but there's also a lot of anxiety about what the judge is going to do," said Vargas' sister, Mindy Galliani.

"I won't have closure until he's home," she added. "But even when he's home, it's still not going to be closure. We need to get him into treatment so he can get help. I feel like this is only the beginning."

Since his arrest, Vargas' family has waged a tireless campaign to reduce the charges and raise awareness over child sex abuse, earning support from members of the community and giving rise to more sex abuse allegations against McNeill.

McNeill used his position as a Boy Scout troop leader and as active neighborhood father to win the trust of Vargas and other young boys, Galliani said. He took the boys on camping trips or hikes, gave them alcohol or drugs and molested them, Galliani alleged.

The alleged sexual abuse waned as Vargas grew into adulthood, but McNeill continued to call him and visit the home where Vargas lived with his wife and infant daughter. The continued contact drove Vargas to the breaking point, his sister said.

Vargas was under the influence of alcohol the night of February 8, 2009, when he drove to McNeill's mobile home with a loaded gun and shot him in front of his wife.
