A convicted sex offender will not challenge new charges that he re-offended in Casper.

Fifty-five year old Lynn Charles Lee, has entered an Alford plea to three amended charges of third degree sexual abuse of a minor (Originally charged with three counts of first degree sexual assault and three counts of second degree sexual abuse of a minor.).

Investigators with the Casper Police Department say in June 2013, the victim claimed that he had been raped and then was told that if he told anyone, he would find his mom dead.

Police learned that Lee had been on parole at the time, after serving 12 years in prison, because he had been convicted of third degree sexual assault back in 2000.

The victim also claimed that Lee ordered him to visit again for more sexual acts, under the threat of blackmail.

As part of a plea deal, prosecutors will seek no more than an 18-28 year prison sentence, followed by a 10-15 year suspended prison sentence with 15 years of probation.

Lee is being held on $150,000 bond and will be sentenced at a later date.

An Alford plea is not an admission of guilt, but it acknowledges that prosecutors have enough evidence and/or testimony, that if the case went to trial, they would be able to get a guilty verdict from a jury.
