HOLLADAY, Utah - Unified Police have made an arrest in an armed jewelry store robbery that took place just over a year ago.

The robbery happened last March at Diamond's Custom Jewelers in Holladay. Police said two suspects entered the store brandishing handguns and demanding that everyone get on the floor. Two customers were injured in the process. An 80-year-old woman sustained hip injuries and an 86-year-old woman sustained face and hand lacerations.

The suspects then broke some glass cases and took jewelry before escaping in a black Pontiac Grand Am. Police were able to identify and locate the vehicle and took 37-year-old Marie Yvonne Heroff into custody.

The other two suspects weren't located, but physical evidence was able to lead them to one of the two suspects.

Now, a 15-year-old boy is in juvenile detention on aggravated robbery charges. Police are still looking for the second suspect.

"You know, to have somebody the age of 14 that's committing such a brazen and heinous crime, is shocking," said Unified Police Lt. Justin Hoyal.

Eric Hancock, the store's owner, says the news of the arrest is a big relief and the age of the suspect is surprising.

"That's extremely unfortunate knowing there's kid's out there doing this stuff," Hancock said.

Hancock says things at the store are pretty much back to normal by now, thanks to police and his loyal customers.

"In fact, it came to our attention how loyal they are when they all flooded in the following day and the following week with their condolences and their concerns. Here I was thinking that it was gonna be such a scary, negative thing and then you realize how great people are," he said.

Police are still looking for the second suspect. He's described as black, over 6 feet tall and around 300 pounds.

Anyone with information is asked to call police at 801-743-5915.
