DOYLESTOWN, Pa. (AP) — Trial has begun for a Florida man charged in the rape and slaying of a 14-year-old Pennsylvania girl more than three decades ago.

Bucks County prosecutors allege that 56-year-old George Shaw, of Geneva, drugged and suffocated Barbara Rowan in Bensalem in August 1984, then dumped her body along a highway. The girl's parents on Tuesday recounted their frantic search after the child disappeared.

Shaw was arrested two years ago and charged in Bucks County with criminal homicide, rape and possessing an instrument of crime.

Also arrested was 53-year-old Robert Sanders, who has acknowledged helping Shaw transport the girl's body and is expected to testify. Sanders awaits sentencing on a guilty plea to hindering apprehension by giving police bad information.

Defense attorney Louis Busico says Shaw "strongly maintains his innocence."
