QUINCY -- Having recently moved to Quincy after spending more than a decade in Oregon, David Anderson asked an area resident for a job, police said.
Then he kept talking, they said, telling the prospective employer that he had broken up with his girlfriend and allegedly showing him graphic letters he had penned to her. The disclosure led police to arrest Anderson, 54, charging that he left female underwear and sexually threatening notes aimed at young girls on at least five doorsteps around town since February.
After the latest incident, in which a father found underwear and a greeting card on his doorstep April 16 warning that his two daughters were being watched, Quincy police officers more aggressively canvassed the neighborhood.
Then, police said, they heard from Anderson's neighbor. He told them that Anderson had asked him if he had any work, and during a casual conversation, showed him the letters he had written to his former girlfriend.
''This piqued his interest," Police Chief Robert Crowley said of the resident, who was not named in a press conference last night at police headquarters.
Police set up surveillance around Anderson's Remington Court home and removed a truckload of garbage to comb through for evidence. Several items -- including an American Girl magazine -- were missing pictures that matched photos included in the packages, police said.
Four of the five packages referred to a girl with whom the suspect was apparently infatuated. Police last night said they have identified the young girl, believed to be 10 or 11, who is an acquaintance of Anderson's. They declined to elaborate on how they know each other.
The packages appear to have been delivered to random homes, two of which have no young female residents, police said. Police arrested Anderson at 6 p.m. yesterday.
Anderson is expected to be arraigned in Quincy District Court this morning on charges of dissemination of obscene material, and making threats disrupting the public, which is punishable by up to 20 years in state prison.
