From Cumberland County Sheriff’s Office:

On January 14, 2026, Cumberland County Sheriff’s Office Deputies and Investigators executed a search warrant on a camper trailer located in the Grandview Community on Garrison Lane as part of an ongoing investigation into an aggravated robbery at the Cumberland Cove Market and Deli earlier this week.

The aggravated robbery occurred on Monday, January 12, 2026, when a white male entered the market wearing a windbreaker, gloves, and a mask, and robbed the store clerk of an undisclosed amount of money before fleeing the scene on foot.

Deputies and Investigators responded immediately and initiated an intensive investigation. Surveillance video obtained from a nearby storage facility placed both the suspect and a black Saturn Vue in the area following the robbery. Through further investigation, Deputies and Investigators located the vehicle on Garrison Road in the Grandview Community.

When Deputies and Investigators attempted to make contact, the suspect barricaded himself inside a travel trailer, resulting in a brief standoff. The suspect was ultimately taken into custody. No injuries were reported during the operation.

The suspect was identified as Joshua Bradley Ruby, age 40, of 290 Garrison Lane, Cumberland County, Tennessee.

Ruby has been charged with:

• Aggravated Robbery (TCA § 39-13-402)
• Aggravated Criminal Trespass (TCA § 39-14-405)

Ruby was also identified as the suspect in a separate incident involving a weapon at a business in the Westel Community on Westel Road in October of 2025, where he allegedly displayed a firearm in a threatening manner toward another individual. He has been additionally charged with Aggravated Assault (TCA §39-13-102).

Crossville Police Department Detectives were notified during the course of the investigation and have also charged Ruby with Aggravated Robbery (TCA § 39-13-402) in connection with the robbery of the Marathon Convenience Market on West Avenue that occurred Friday night.

Ruby is being held in the Cumberland County Jail pending his court appearance February 23, 2026 on a $400,000.00 bond.

This investigation remains ongoing. No additional information is being released at this time.
