UNION CITY -- A woman impersonating a city employee duped two elderly residents into entering their home on Wednesday to investigate an alleged snake infestation, while police say an accomplice burglarized their home.

The two roommates told police that while the thieves were inside, cash, jewelry and other items were taken from their home in the 32200 block of Deborah Drive, Union City Cmdr. Ben Horner said.

The victims told police that just before 6 p.m. a woman knocked on their door, identified herself as a city employee and told them she was there to check for a snake infestation.

The woman wore uniform comprised by a dark blue hat with a "CITY" logo on it, a dark green shirt with the same logo over the left chest area and dark green pants.

She did not offer to show an picture ID card.

The victims described her as a white or Hispanic female with blonde hair that may have been dyed or possibly even a wig.

While the woman distracted the victim, police said, it's believed an unknown cohort entered the home and stole items including jewelry and cash. The exact monetary value of the items was not released and the victims did not see the woman's partner-in-crime, police said.

Neither roommate was injured.

Horner said Union City workers carry photo identification cards and if residents have question as to the legitimacy of a city worker they should contact police.

No other similar burglaries have been reported in Union City, Horner said.

Anyone with questions or with information about the burglary can call police at 510-675-5247.
