Milford police are warning residents to remain vigilant after a rash of break-ins last Friday brought the total to 19 residential burglaries over an 8-week period.

Police said there were three home burglaries reported last Friday evening in different sections of town. One incident occurred on Lower Naugatuck Avenue on the town’s west side, another on High Street in the center of town and the final one was reported near Joseph A. Foran High School.

Devito said that the three robberies fit a similar pattern to the other burglaries that have been plaguing the area since late December.

“Last night was the perfect example of what’s occurring here,” said Pfc. Mike Devito, a Milford police spokesman.

For one, police said the perpetrators have been using rocks or bricks found nearby to break windows and gain entry to homes. The break-ins have also all occurred between 4 p.m. and 8 p.m. — which Devito said is an unusual time for burglaries to occur.

Once inside, police said the burglars tend to target jewelry, loose cash, small electronics and, in some instances, even guns. None of the stolen items have been recovered by police.

Milford police are joined in their investigation by Stratford authorities, who also have seen an uptick in similar burglaries since December. Between the two towns there have been nearly three dozen burglaries, Devito said.

So far, police have no leads on the suspects, yet they are continuing to investigate.

“We’re trying to see if we can draw some type of parallel between the victims. We’re really at the infant stages but we’re working tirelessly to see if they used the same maid service or cleaning service, trash service, a recent contractor. Some type of recent work done in the neighborhood to link what is similar between the victims,” Devito said.

On Thursday, Milford residents received an alert by text, email or phone. The warning let them know about the string of home burglaries and asking them to report anything suspicious.

Until the perpetrators can be caught, police are reminding residents to keep cash and valuables locked away and out of sight.

Police also wanted to remind residents to report anything suspicious — an unfamiliar car parked in the neighborhood, an unknown.

“We are urging residents of Milford and Stratford to call police if they see anything suspicious. If you see anything out of the ordinary. —and right now that could just be a car that doesn’t seem familiar to the area or a jogger or someone walking that you’ve never seen before.

Then call the police,” Devito said.

If residents see anything unusual, they are asked to call the Milford Police Department at 203-878-6551 or the Stratford Police Department at 203-385-4100.
