(MTN News-GREAT FALLS) Sean Michael Grumbein has been charged after allegedly breaking into and stealing from the Petcetera store in Great Falls.

The incident happened at about 4:30 a.m. on Tuesday, January 19th, when a Great Falls police officer was dispatched to the Petcetera store at 1525 10th Avenue South for a report of an alarm.

When he arrived, the officer found that a large window had been broken, and it appeared that several items had been taken from the store.

The officer noted wet hand-prints going back toward the aquarium area of the shop.

The owner of the store told the police that several “Live Rocks” and a Lunar Aqualight had been stolen; the estimated cost of the stolen items is $623.

A witness told police that a green Subaru Outback had been scene driving away from the store at about the time the robbery occurred, and the witness said the driver was a middle-aged white man with a red hat and goatee.

According to court documents, some time later, a police officer observed a green Outback driving around the perimeter of the store several times.

The store owner also saw the car, and was able to identify the driver — later confirmed to be Grumbein — from having spoken with him several times in the past.

Officers also discovered that Grumbein had gone into Petcetera recently and expressed interest in the items that had been stolen.

The police affidavit states that the Subaru is owned by a woman that Grumbein lives with, and that a fish tank seen in the Grumbein’s apartment matches the description of the one that was stolen from Petcetera.

The affidavit also states that numerous stolen items were found inside the residence.

Grumbein has been charged with felony burglary, misdemeanor theft, and misdemeanor criminal mischief.

According to state prison records, Grumbein has felony convictions in Cascade County for burglary, criminal mischief, and criminal possession of dangerous drugs with intent to distribute.

Court documents state that he also hasĀ misdemeanor convictions for theft, forgery, and criminal possession of drug paraphernalia.

Prosecutors requested that bond for Grumbein be set at $25,000.
