According to his plea agreement, on August 19, 2013, Gilliam robbed a cell phone store in the 800 block of Taylor Avenue in Towson. Gilliam told a store clerk that he wanted to switch his phone service. Gilliam lingered in the store until there were no other customers, then approached the cash register with his hand in his pocket, as if he were carrying a handgun. Gilliam leaned over the register counter and yelled at a store employee demanding all the money from the register. Gilliam took approximately $300 from the store, then ordered the store clerk to the back of the store and ordered another employee to go outside. Gilliam then ran away.
