A Casper woman denies claims that she sexually assaulted a 13-year-old boy.

Britney Rosenfield entered a pair of not guilty pleas to one count of first degree sexual assault of a minor and one count of second degree sexual assault of a minor in Natrona County District Court on Wednesday.

Prosecutors say Casper Police were first notified of the alleged sexual assaults on Oct. 24. Prosecutors claim Rosenfield has had a sexual relationship with the boy since August.

Rosenfield, who also goes by the name of Britney Olson, is currently being held on $50,000 bond. She faces up to 50 years in prison if convicted.
