ST. LOUIS (AP) - The last of 19 defendants charged in connection with one of the largest robberies ever in St. Louis has been sentenced to 15 months in prison.

A federal judge on Tuesday sentenced 26-year-old Jacobi Oliphant for helping to conceal some of the $6.6 million taken in the ATM Solutions robbery.

The crime occurred on Aug. 2, 2010, when four armed bandits clad from head to toe in black overpowered two workers at the St. Louis office of ATM Solutions, an ATM-servicing business, then used an armored vehicle to haul away containers filled with cash.

Along with the four suspected robbers, 15 others were charged with crimes related to the heist, many for helping to hide the money.
