A convicted child molester who suffered a vigilante beating for his crimes against two girls will spend the next six years in prison after pleading guilty to sex abuse charges Tuesday.

Mark Alexander Tabor, 24, admitted to molesting two young sisters while he was a guest in their home in August 2011.

Tabor pleaded guilty to two counts of first-degree sexual abuse and one count of second-degree sexual abuse. First-degree sex abuse is a Measure 11 crime that carries a mandatory minimum sentence of six years, three months in prison.

As part of his plea agreement, Tabor's sentences for all three crimes will run concurrently, meaning he will spend a total of just over six years in prison.

Tabor's case came to the attention of police after he was the target of vigilante justice by two men who discovered that he had molested the girls, said prosecutor Terry Smith-Norton.

The two men, who were friends of the victims' family, apprehended Tabor, armed themselves with a baton and a wrench and drove Tabor to the Elderberry Flats campground about 20 miles north of Rogue River.

Once there, police said, they beat Tabor until he managed to flee the area. He managed to get a ride with someone, and was dropped off at a gas station. From there he was taken to Asante Rogue Regional Medical Center, where he was treated and released for a blow to the head.

As sheriff's deputies were investigating the beating, they learned of the sex abuse that sparked the incident.

The victims, ages 13 and 14, gave a statement in the courtroom on Tuesday. The girls' mother said Tabor preyed on the sisters numerous times. She said one of the girls had been sexually abused previously, something she said Tabor knew about.

One of the victims asked Jackson County Circuit Court Judge Tim Barnack to put Tabor in jail for a long time and to make sure he never has contact with the family again. The judge praised her for her courage in appearing in court.

"You put a predator in prison, which is were he's supposed to be," Barnack said to the girl. "You should be proud of yourself."

Defense attorney Bob Abel argued that the sentences should run concurrently because this was Tabor's first serious criminal offense.

Tabor is required to register as a sex offender for the rest of his life and was sentenced to 10 years of post-prison supervision.

The two men who committed the vigilante attack against Tabor received probation, but no prison sentences.
