HONESDALE, Pa. (AP) - Jurors in northeastern Pennsylvania have acquitted a Virginia man on all counts in the murder of a camp counselor almost two decades ago.

The panel deliberated for about 3½ hours Tuesday evening before finding 47-year-old Jeffrey Plishka of Onley, Va., not guilty in the 1991 slaying of 24-year-old Laura Ronning in a remote part of Wayne County.

Plishka was released from custody after the verdict and left the courthouse with his father, Metropolitan Opera singer Paul Plishka, and stepmother.

Ronning was a counselor at Camp Cayuga when she disappeared on July 27, 1991, while walking to Tanner's Falls, near Honesdale. Her body was discovered the next morning.

The defense argued there wasn't enough evidence to convict and sought to shift blame to two unknown men seen flirting with the victim a few days earlier.
