TISBURY, Mass. (WPRI) — Two men arrested in connection with a bank robbery on Martha’s Vineyard last month are now facing additional federal charges, according to United States Attorney Rachael Rollins.

Miquel Antonio Jones, 39, of Edgartown, and Omar Odion Johnson, 32 of Canterbury, New Hampshire, have both been federally charged with armed bank robbery.

Johnson was previously charged with masked armed robbery with a firearm and conspiracy, while Jones had been charged with accessory after the fact.

Rollins said three suspects armed with handguns forced their way into the Rockland Trust bank wearing matching white masks resembling elderly men.

One of the suspects forced a banker employee to open the bank’s vault at gunpoint, according to prosecutors.

Rollins said the suspects stole more than $39,000 from the bank before binding the employees with duct tape and zip ties.

The suspects then took off in one of the bank employee’s vehicles.

Rollins said detectives found the stolen vehicle abandoned in a nearby parking lot, where it is believed the suspects hopped into another car.

Investigators identified Jones as one of the suspects after finding “a significant amount of evidence connected to the robbery” on a farm in Tisbury where Jones worked, according to prosecutors.

Rollins said detectives found plastic consistent with a white mask, scraps of nylon, paper money bands and walkie-talkies parts that all appeared to have been burned in a recent fire. Investigators also reportedly found two handguns buried nearby.

Jones was apprehended a few days after the robbery. Johnson was arrested last week during a traffic stop in New Haven, Connecticut.

The robbery remains under investigation and police are still searching for the remaining suspect.

Anyone with information is urged to contact the Tisbury Police Department at (508) 696-4240 or Massachusetts State Police Trooper Dustin Shaw at (508) 693-0545.
