A prostitution charge was dropped Tuesday in Pembroke Town Court against a former reality TV star from Williamsville, according to the Genesee County District Attorney’s Office.

Alicia Guastaferro, 21, who faced scorn and ridicule after appearing with her family on ABC’s “Wife Swap” in 2008, still faces charges of possession of a controlled substance and criminal impersonation in the Aug. 27 incident, in which she was found in a car at a Thruway rest stop with a Rochester attorney slumped over the wheel.

Guastaferro, then 20, and James D. Doyle, 54, were found “improperly parked” at the Pembroke service area shortly after midnight by a trooper investigating a report of an erratic driver.

Guastaferro told investigators that Doyle regularly paid her for sex, bought her alcohol and provided her with a fake ID so that she could drink with him.

However, Assistant District Attorney Robert Zickl told The Buffalo News on Wednesday that further investigation by state police found the prostitution charge was not merited and that it was dropped at his office’s request.

Prosecutors also dropped a charge of patronizing a prostitute against Doyle, but he still faces charges of driving while intoxicated and unlawful dealing with a child, as well as numerous traffic violations. Both Doyle and Guastaferro have denied wrongdoing.

Guastaferro is due back in Town Court on March 12.
