SAYREVILLE — A 20-year-old male daycare worker has been charged with sexually abusing children while his employer was charged with failing to report the abuse.

Kyle Finn, of Sayreville, was arrested Wednesday and charged with sexually abusing and endangering three children, according to a joint release from Middlesex County Prosecutor Yolanda Ciccone and Sayreville Police Chief John Zebrowski.

On Sunday, Finn was hit with additional charges of sexually abusing a fourth child and on Tuesday, police added assault charges involving a fifth child.

As of Tuesday night, Finn faced a total of six counts of first-degree aggravated sexual assault, seven counts of second-degree sexual assault and five counts of second-degree endangering the welfare of a child with the charges varying victim-to-victim, the prosecutor's office announced.

Finn had been an aide at the Superhero Schoolhouse Day Care in the Parlin section of the borough and has since been fired, Ciccone and Zebrowski said.

Also Sunday, the day care director, 44-year-old Charmaine Larkin, of South River, was charged with failure to report child abuse, a disorderly persons offense.

Finn has worked as a camp counselor for Our Lady of Victories Parish Church in Sayreville and the Sayreville Department of Recreation, according to Ciccone, who said the 20-year-old also has volunteered for the Sayreville Association for Brain Injured Children.

Finn and Larkin were charged following an investigation by Sayreville Police and the Middlesex County Prosecutor’s Office that determined four children were sexually abused at the daycare center.

As of Monday, Finn was being held at Middlesex County jail pending a detention hearing in Superior Court.
