State Police Trooper accused of child abuse facing more charges

A state police trooper accused of child abuse faces more charges of illegal wiretapping and violating an abuse prevention order, prosecutors said.

Michael Gagnon, of Plympton, was initially arrested in November and arraigned on charges of domestic assault and battery and aggravated assault of a child under 14, Plympton police said at the time.

Gagnon, who has since been suspended by the state Police Oversight Commission, is now charged with illegal wiretapping and violating an abuse prevention order, according to Michael Keefe Feldman, a spokesman for the Essex County District Attorney’s Office.

Keefe Feldman said the charges stem from incidents that occurred on March 10. He refused to provide more information.

Gagnon is expected to be arraigned on both charges in Plymouth District Court on Monday. The arraignment will be conducted by a prosecutor from the Essex County DA’s office, Keefe Feldman said.

The initial allegations of child abuse came after an investigation by the Plymouth County Prosecutor’s Office, the Department of Children and Families and Plympton Police. The victim told DCF he was punched in the face by Gagnon, according to WCVB.

“Michael Gagnon then advised the children to say that the bat caused the mark and that it was accidental,” the report said. Per WCVB.

In January, Gagnon was also charged with felony witness intimidation, according to court documents, and has pleaded not guilty. His attorney, Kevin Reddington, did not respond to a request for comment Sunday evening.

When contacted for comment, Massachusetts State Police said Gagnon had been suspended without pay effective December 1.

“Massachusetts State Police stands firm against all forms of domestic violence and has taken final action in this case to relieve the officer from duty and suspend him without pay in December 2025,” the spokesperson said. “We will be pursuing the court proceedings as part of our ongoing investigation into employees and await the outcome of that process.”
