COLUMBUS, Ohio: A man who skipped his own armed robbery trial after stripping naked and wiping feces on his body is heading to prison.

The Columbus Dispatch reports that Wendell Watkins Sr. was sentenced Monday in Columbus to 20 years in prison.

Watkins and two others were charged with robbing a Columbus man of more than $35,000 in casino winnings in October 2012. The trial was ordered to continue without Watkins after authorities found him naked on a jail toilet.

A psychologist found that Watkins was pretending to be mentally ill.

The 33-year-old Columbus man was convicted of charges including aggravated robbery and aggravated burglary.

Watkins said in court Monday that he is not crazy and his only law is God.

His attorney told the judge her client has mental-health problems.
