"The MO appears to be the same," Lieutenant Mark Marino said. "That leads us to believe there is a connection to an individual or individuals."
The most recent burglary happened February 5 on Maplewood Drive. Police say the resident returned home and found the master bedroom ransacked and jewelry stolen. There was reportedly no evidence of forced entry.
The other three incidents, all similar in nature, occurred three weeks earlier in a two-day span.
Residents are being urged to keep windows and doors locked at all times. Authorities say that alarm systems are especially effective, and that it's important to make vacant houses look lived-in when residents are away. They say newspaper and mail delivery service should be suspended, or a trusted neighbor should pick them up.
