A Level One Sex Offender serving 30 years for raping a girl known to him is fighting his conviction.

Duayne Peters had his appeal heard in the Supreme Court of Guam last week.

Attorney Joshua Walsh argued Peters should be granted a new trial.

"Mr. Peters stands convicted in a case where his trial counsel took no pretrial effort to obtain relevant discovery where it’s probative to the allegations made against him. Mr. Peters was also convicted upon the testimony of his co-actor who was accused of participating in the abuse at the heart of this case but was promised a plea agreement guaranteeing no jail time so long as she testified against (defendant)…Mr. Peters had ineffective trial counsel during the discovery phase of this case," he said.

As KUAM reported, Peters along with his wife, Natasha Peters, was convicted for sexually assaulting a child from March 2012 to January 2019. The victim was about 11 years old when the abuse began. 

Natasha, who pleaded guilty to criminal facilitation of st degree criminal sexual conduct, was placed on one year unsupervised probation - spared jail time.  She testified against duayne at his trial and has since reconnected with the victim.

Prosecutor Christine Tenorio said, "In this case, she was charged with complicity so Mrs. Peters did not herself sexually assault the child. It was that she promoted or assisted Mr. Peters in doing so."

"In this case there are a lot of extenuating and as long as the plea agreement is legal, which it was, she plead to facilitation of the event that was underlying Mr. Peters conviction then those should be upheld as not being coercive."

Justices are mulling over a decision.
