MANCHESTER, NH – Last week, a Manchester School District employee alerted DCYF to a potential sexual abuse case involving an eight-year-old student. The counselor reported the case after the girl made several remarks to him, prompting the Juvenile Unit to launch a criminal investigation.
On November 14, Detective Stephen Flynn, Detective Robert Tremblay and a DCYF employee responded to the victim’s Manchester address to conduct an investigation. She was temporarily placed with a family member to ensure her safety.
Detectives interviewed the victim at the Child Advocacy Center to gather information regarding the alleged assault(s). The suspect was identified as the boyfriend of the victim’s mother, who had been living with the girl and her mother for at least seven years. Investigators believe the pattern of sexual abuse occurred over a period of at least two years, and applied for an arrest warrant for Alexander Mathieu, 25 of Manchester, New Hampshire.
Mathieu was located and arrested on November 19 without incident, and was charged with pattern AFSA (aggravated felonious sexual assault). Mathieu appeared before Hillsborough County Superior Court-North on November 20, and was issued a $20,000.00 cash/surety bail. He remains incarcerated at this time and the victim remains in the temporary custody of a family member.
Members of the Manchester Police Juvenile Unit, Manchester School District, Child Advocacy Center and DCYF worked collaboratively to assure the victim’s voice was heard and the perpetrator was quickly arrested for his alleged crimes.
