WILKES-BARRE, Pa. -- A northeastern Pennsylvania man accused of injecting his semen into the food of two co-workers has pleaded guilty in federal court to tampering with a consumer product.

Sixty-year-old Joseph Bartorillo of Larksville entered the plea Wednesday in federal court in Wilkes-Barre in an agreement that stipulates a two-year prison term. A sentencing date has not been set.

Defense attorney Demetrius Fannick told The (Wilkes-Barre) Times-Leader that his client was "very, very remorseful" and there was "no logical reason" for his actions, since he barely knew the two women involved at the Wyoming County workplace. Fannick said "I don't think even he knows why he did it."

Bartorillo was released on his own recognizance as long as he continues mental health treatment.

Larksville is about 100 miles northwest of Philadelphia.
