A Roslindale man was arraigned today on charges he punched a woman in the face in the Arnold Arboretum and then raped her repeatedly on Aug. 13, 2013, and will be arraigned on Monday on charges he raped a 16-year-old on Morton Street in Mattapan on April 1, 2007, the Suffolk County District Attorney's office reports.
Bail for Irving Pierre, 40, was set at $25,000 for the Arboretum attack in West Roxbury court, the DA's office reports, adding he will be arraigned for the Morton Street attack in Dorchester court.
The cases had lain dormant until January of this year, after police submitted DNA samples from both cases to the FBI's national DNA database. The database showed the same man was likely responsible for both cases, but did not match any men already in the database, according to the DA's office.
In January of this year, the database found a match between the DNA samples in the two cases. The match indicated that the same, unknown individual committed both assaults, but it did not link the samples to a known offender. Through the course of a renewed investigation, Boston Police detectives identified Pierre as a suspect and obtained his DNA from a discarded nip bottle that he was observed drinking from. That DNA sample was subsequently matched to the previously unsolved attacks.
Pierre turned himself in yesterday at the West Roxbury police station, police report, adding they are now looking for evidence that might link Pierre to other attacks.
