A man who police considered a “habitual flasher” was sentenced to state prison Tuesday for exposing himself to children at the Brookline Public Library, officials said.
John Beyers, 68, of Brighton was arraigned Tuesday in Norfolk District Court in two separate incidents of exposing himself to children at the Coolidge Corner branch of the Brookline Public Library on Sept. 21 and 26, 2013, said David Traub, a spokesman for Norfolk District Attorney Michael W. Morrissey.
Beyers pleaded guilty to two counts of open and gross lewdness and two counts of annoying and accosting a person of the opposite sex, Traub said. Beyers was sentenced to 30 to 36 months in prison, followed by five years’ probation.
Brookline police were able to identify Beyers following the incident in September by comparing library surveillance video to his sex offender registry photo, Morrissey’s office said. Detectives were also able to track him through the GPS monitoring device he wore as part of his probation for an earlier sexual offense.
The state Sex Offender Registry Board lists Beyers as a Level 3 sexual offender. The state considers Level 3 offenders to be at “high risk to reoffend and pose a high degree of dangerousness to the public.”
