Two of the three were also charged in connection with a plot to commit a third robbery.
Elizabeth A. Albertson, 28, Charles Richards, 28, and Brian Hawthorne, 26, were all charged with armed robbery and conspiracy for the Jan. 16 robbery of a 7-11 on Route 73 in Mount Laurel.
All three were also charged with armed robbery, possession of a weapon for an unlawful purpose and unlawful possession of a weapon for the Jan. 26 robbery of Food Mart on Route 130 in Delran.
Hawthorne and Richards were lodged in Burlington County Jail in Mount Holly. Bail was set for Richards at $350,000 following his first appearance on Monday. Albertson was placed in the Correction Work Release Center in Pemberton Township.
Florence Police arrested Hawthorne and Richards on Feb. 7 after a citizen reported a suspicious vehicle parked in the area of Wallace Avenue and Seventh Street.
Police searched the vehicle and discovered a ski mask, a handgun and a small amount of suspected heroin.
Police determined Hawthorne and Richards were preparing to rob a liquor store in Florence when they were apprehended. They were charged with conspiracy to commit armed robbery and possession of a weapon for an unlawful purpose.
Richards was also charged with certain persons not to have weapons.
A further investigation determined that Albertson, who lives with Richards on Kelso Lane, was also involved in the robberies.
“Investigators were greatly assisted in this case by an alert citizen who recognized that something was not quite right and took the time to call Florence police,” Bernardi said. “This type of help is extremely valuable to law enforcement and I encourage all members of the public to call their police departments when they suspect illegal activity is occurring.”
