WESTERLY — Detectives with the Westerly Police Department are investigating two break-ins at homes on Mountain Avenue that occurred early Monday morning.Westerly Police received information from the homeowners of 12 and 16 Mountain Ave., reporting an attempted break-in at the first home and a break-in at the second, with cash from a wallet stolen at the second home, according to Police Chief Edward St. Clair. The break-ins included unlocked vehicles outside both homes, from which loose change was taken.St. Clair said the incidents are still under investigation by department detectives, but they believe the events may be connected to an earlier series of thefts from unlocked cars throughout town.Last week, the department arrested three juveniles for the break-ins.“They may not have been responsible for these incidents, but we believe there are others,” St. Clair said.Detectives are processing fingerprints lifted from several locations within the homes, and have a few leads on possible suspects, according to St. Clair.Carlo Giorno, owner of the residence at 12 Mountain Ave., said he was home when the thief broke the screen on one of his windows around 3 a.m. Monday morning. Giorno believes that when he heard the noise and got up to investigate, he scared the suspect away. Giorno added that when he let his dog out, he heard the animal barking at and chasing someone away. His neighbors’ home at 16 Mountain Ave. was also broken into, and cash was stolen from a wallet when the homeowners discovered the break-in later that morning. In both incidents, Giorno said people were home when the thief tried to break in.“It’s incredible to me that they actually got in, or tried to, while there were people sleeping upstairs,” Giorno said.Since the incident, Giorno and his neighbors have purchased alarm systems for their homes.“Everyone’s stepping up, trying to be more cautious and alert,” he said.Anyone with information regarding the break-ins is asked to call the Westerly Police Department at 401-596-2022.
