A total of approximately $1,500, several packs of cigarettes, bottles of alcohol were stolen in the robberies.
Armell was arrested May 22 after police said they received a tip from a woman identifying herself as Armell's on-again, off-again girlfriend, who told investigators that Armell told her he committed the robberies while high on drugs. Police used information gleaned from Armell's Facebook page to build the case against him.
