Former Boston deputy fire chief who posed as police officer is sentenced to 18 to 20 years for series of rapes

A Brockton Superior Court jury convicted a former Boston deputy fire chief today on more than a dozen charges stemming from a series of rapes in which he lured women into his car by impersonating a police officer, prosecutors said.

Peter Pearson, 56, of East Bridgewater, was convicted of five counts of aggravated rape, one count of assault with intent to rape, four counts of kidnapping, two counts of indecent assault and battery, and four counts of impersonating a police officer, Plymouth District Attorney Timothy J. Cruz said in a statement. Pearson was sentenced to 18 to 20 years in prison followed by five years of probation.

“Today’s verdict brings justice for five women who found the strength to come forward to testify about unspeakable crimes,” Cruz said. “As a result of their sacrifice, a predator of eleven years is off the streets.”

Pearson was arrested in 2008, the statement said.

Pearson used his firefighter’s badge, a handheld radio, and sometimes a gun to further the illusion that he was an officer and lure his five victims into his car, where he forced them to perform sexual acts, the statement said.
