JERSEY CITY -- A retired Kearny cop who coached boys basketball at Kearny High School is facing allegations that he groped a 17-year-old girl at the school over the summer.

Robert McDonnell, 59, of Chestnut Street in Kearny, has been charged with criminal sexual contact and endangering the welfare of a child after the girl told the authorities in July that he grabbed her buttocks and kissed her on her neck on separate occasions, according to a criminal complaint.

Kearny Superintendent of Schools Patricia Blood told The Jersey Journal on Tuesday that McDonnell was not rehired to coach the school's boys basketball team this year.

McDonnell could not be reached for comment on the charges. A woman who answered the phone Tuesday afternoon said he was unavailable.

Blood said McDonnell was running a boys basketball camp at the high school on July 23 when the alleged incident involving a member of the school's girls basketball team occurred. Blood added that McDonnell was not working for the Board of Education at the time of the incident.

According to Blood, members of the girls team had stopped at the school that day to get their gear before playing in a summer league game. The victim told police she entered a closet in the school's gymnasium to get a basketball and that McDonnell followed her in and "smacked her buttocks," according to the complaint.

The girl told police that McDonnell had previously made "inappropriate comments" toward her and other girls, adding that in November 2017 he kissed her on her neck, the complaint states.

She also said McDonnell had given her a business card and told her to call him, the complaint alleges.

Investigators recovered video from the gym showing McDonnell entering the closet after the 17-year-old had gone in and closing the door behind him. The girl's mother told authorities that McDonnell had also told the girl they would be married if they were the same age, according to the complaint.

The Hudson County Prosecutor's Office Special Victims Unit filed charges against McConnell on Oct. 4 and his first court appearance was scheduled for Oct. 25, the complaint says.

McDonnell was hired as the school's boys basketball coach in 2013. It's unclear when he retired from the town's police force, but currently collects an annual pension worth $101,084, state pension records indicate.
