According to police, an 89-year-old female let a male, who claimed to be from the water department, into her home.

Police say the victim looked at the suspect’s ID tag, which had a photo of him and said “Water Department” on it, and allowed him into her basement.

Allegedly, the suspect, who identified himself as “Bob” stood on one side of the basement and instructed her to turn the water on and off while she stood on the other side of the basement. The victim says the suspect also allegedly used his cell phone to call someone while they were in the basement. The suspect then went upstairs, ran out of a side door and kept running towards Front Street, says police.

Authorities say nothing seemed to be disturbed, but police received a phone call from the victim’s sister later that day asking for officers to return to the victim’s residence.

Police say the sister told officers that two of her small safes were missing when she got home and a third safe was open with pry marks around the handle and lock. Officials report two of the safes were found under a bed and one was found on the floor.
