APRIL 14--Putting the strip in strip mall, a 21-year-old Pennsylvania woman wearing only high heels and black stockings was arrested on indecent exposure charges after she was spotted posing for provocative photos outside a shopping center, police report.

Chelsea Guerra, 21, responded last week to a Craigslist ad seeking a nude female model, cops say. The ad was placed by Michael Warnock, a 63-year-old Pittsburgh resident.

According to investigators, after Warnock gave Guerra (seen at right) a $300 check, the duo began their photo shoot outside the Miracle Mile Shopping Center in Monroeville, a city about 15 miles east of Pittsburgh.

Warnock, cops allege, was snapping photos of the naked Guerra around 11 AM last Saturday, which caught the attention of witnesses (at least one of whom called 911). Guerra and Warnock--who appears to be an amateur lensman--were arrested when cops arrived at the strip mall.

Guerra, charged with indecent exposure and disorderly conduct, was released from the Allegheny County jail on her own recognizance. Warnock was charged with solicitation, conspiracy, disorderly conduct, and narcotics possession. He was freed from custody after posting $500 bai l.

Guerra and Warnock (pictured at left) are scheduled for a June 19 District Court hearing.

According to her LinkedIn page, Guerra works as a “greeter” at a Toyota dealership and is studying “Public Relations/Image Management” at Indiana University of Pennsylvania.
