A former Casper resident waived his preliminary hearing and was bound over for trial in district court on sexual assault charges on Thursday morning.

A few hours later, Carroll Michael Chaisson, waived a fugitive warrant from Colorado in Natrona County Circuit Court.

Neither Assistant District Attorney Mike Schafer nor Circuit Court Judge Michael Patchen said why Chaisson was wanted in Colorado.

However, his case involving the alleged sexual abuse of a girl that occurred more than four years ago started in Colorado.

Last month he was charged with of two counts of first degree sexual assault and one count of second degree sexual assault. The first-degree sexual abuse charges each carry penalties of up to 50 years imprisonment. The second-degree sexual abuse charge carries a penalty of up to 20 years imprisonment.

Because Chaisson now lives in Fargo, N.D., and has virtually no ties to the Casper community, Patchen set his bond at $75,000.

The case began locally last month when Natrona County Sheriff’s investigator Aaron Shatto reviewed a report of a girl who had been interviewed by a detective in Colorado, according to his affidavit filed in Natrona County Circuit Court.

The girl, who had been Chaisson’s step-sister when the two lived in the same household in Casper, told the detective she was six or seven when the abuse began and ended when she was 11 or 12, according to the affidavit.

The most recent alleged abuse occurred in December 2010, when Chaisson was a student at Casper College. Chaisson’s mother had kicked him out of her house that summer, and he lived with the girl’s aunt and uncle until January or February 2011, according to the affidavit.
