Former Primos Elementary School principal found not guilty of sexually abusing former students

The former principal of Primos Elementary School in Upper Darby was acquitted Thursday of charges that he inappropriately touched two students in his office in 2018.

Jonathan Wisneski, 45, of Springfield, was charged in February 2022 after prosecutors in Delaware County reexamined evidence from a previous investigation that did not result in charges against him.

At the time of the initial investigation in 2018, Wisneski had been working at Primos Elementary School, part of the Upper Darby School District, for two years. He left the school after the initial investigation was completed.

Prosecutors later filed charges against Wisneski after conducting forensic interviews with the students, who accused him of touching their buttocks and otherwise behaving inappropriately.

Wisneski sometimes invited students to eat lunch with him as a reward, investigators said. During his trial, Wisneski testified that he never let students come into his office alone with him and that the door to the office was generally left open so that teachers and secretaries could stop by, the Delaware County Daily Times reported.

The jury deliberated for less than three hours before delivering the verdict to Common Pleas Court Judge Anthony Scanlon. Wisneski was found not guilty of indecent assault, sexual contact with a student, endangering the welfare of children and corruption of minors.

Wisneski is currently on administrative leave from Devereux CARES School in Downingtown.
