Prosecutors say the people who were present described being "in fear for my life," "petrified" and "scared to death."

Authorities learned that the previous day, Nov. 2, a man had come into the store, looking for a "bridal set in the dollar range of $15,000 to $18,000." The complaint states that the man asked if there were additional diamonds kept in a vault, and "appeared to be counting the number of display cases, familiarizing himself with the layout of the store."

Authorities say they were able to track down the suspects using the GPS tracking device that was taken in the robbery. Marquell Lamar Evans, 28; Trevon Shukur Edwards, 19; and Antoine Devell Scott, 26; are all charged with felony aggravated robbery.
