A Utah State Prison inmate whose criminal record has continued to grow, even while incarcerated, made a brief appearance in 3rd District Court Friday.

Nathan Redcap, 22, was charged in 2006 with attempted aggravated murder and having two items prohibited in prison.

While already an inmate, prosecutors say, Redcap stabbed another inmate several times using two metal homemade shanks, one tied to each hand. Redcap also wore "body armor" made by attaching multiple magazines to himself, during the attack.

A jury trial on that charge was scheduled to begin Jan. 29. That was canceled Friday after defense attorney Brennon Fuelling told Judge Deno Himonas he plans to file motions in an attempt to keep Redcap's criminal history out of the trial and to fight enhancements on the charges.

His next court appearance on that case is scheduled for Feb. 1.

Redcap was sentenced to prison in 2002 after pleading guilty to first-degree felony rape and second-degree felony attempted murder.

While incarcerated, he was charged again with the attempted murder and charged in 2007 with forcible sodomy, a first-degree felony, after prosecutors say he attacked another inmate.

Redcap is currently housed in Uinta 1, the most secure facility of the prison, according to the Department of Corrections. He does not have any cell mates and all the inmates of that facility are only allowed out of their cells one at a time.

Redcap wore an orange prison jump suit Friday with his hands cuffed behind his back. He did not say anything during his brief appearance.
