Lehigh County District Attorney Gavin P. Holihan announced the sentencing of a former KidsPeace employee who admitted to assaulting a juvenile patient, causing injuries that included broken fingers on both hands.

Kellin Jesse Miller, 30, of Whitehall, pleaded guilty to misdemeanor counts of endangering the welfare of children and simple assault. During a Sept. 8 hearing before Lehigh County Judge Robert L. Steinberg, Miller was sentenced to 60 months of probation.

According to the district attorney’s office, prosecutors sought a jail sentence, but Steinberg instead imposed a sentence below both the mitigated and standard guideline ranges for an assault involving a child. Miller received no jail time and will remain free on probation.

Miller is no longer employed at the KidsPeace facility at 5300 KidsPeace Drive in North Whitehall Township.

Pennsylvania State Police and the Lehigh County District Attorney’s Office began investigating a report of suspected child abuse at the facility July 11, 2025.

The victim, a 10-year-old boy whose identity is being withheld, was receiving inpatient care at KidsPeace at the time of the assault. According to investigators, the boy’s parents learned June 20, 2025, that he had sustained broken fingers on both hands. The injuries required surgery, and the child was later removed from the facility.

Authorities said surveillance video played during the Sept. 8 sentencing hearing captured the entire incident.

Investigators determined Miller was responsible for supervising the child when the injuries occurred. According to the district attorney’s office, surveillance footage showed Miller alone with the victim and appearing to intentionally bend the child’s fingers in an unnatural manner while attempting to restrain him. The video reportedly showed the child displaying immediate signs of pain and distress following the incident.

As a mandated reporter of child abuse and neglect, Miller was required to report the injuries but failed to do so, according to authorities.

Prosecutors said the child went nearly two days without medical treatment because Miller failed to report the incident and the injuries as required by law and facility policy. The victim ultimately received medical care after his parents became aware of the assault.

Miller was arrested following the investigation and remained free on bail until sentencing.

The case was prosecuted by Chief Deputy District Attorney Sara A. Moyer and investigated by Pennsylvania State Police Trooper Ryan Cordingly.
