The robberies occurred Oct. 13 at the Conoco at 993 West Girard Ave., Cedartown and Oct. 16 at the Marathon Station across from Polk Medical Center.
The three arrested are:
Meagan Elizabeth Brett, 19, of 32 Darnett Court, Dallas, charged with party to a crime of armed robbery; Paul Manuel Wofford Jr., 21, of 615 North Bellview Road, Aragon, charged with robbery by sudden snatching and armed robbery; and Trent Lee Watson, 25, of 2416 Cupp Lake Road, Cedartown, charged with armed robbery.
Newsome said Watson will also be charged in with sudden snatching.
The men are suspected of stealing a .45-caliber handgun in a sudden snatching at the A-1 Motor Lodge on North Main Street Oct. 13, just hours before the first robbery at Conoco, Newsome said.
He said evidence indicates that was the gun used in both robberies.
All three remain in the Polk County Jail.
Newsome said the arrests come after a lot of police work and numerous tips. He said police had a setback when their first suspect turned out to be the wrong guy.
“We had several people dedicated to this case. We had probable cause and made an arrest on Tony Jay McBurnett,” Newsome said of the Oct. 15 arrest of the Waco, Ga., man.
“Subsequent investigation ruled Mr. McBurnett out because we had an alibi for him.”
Newsome said his department immediately asked the court to drop charges against McBurnett and release him.
McBurnett was released Oct. 16.
Newsome said a source came forward after the Marathon robbery and that tip led to Brett and Watson, who were staying at a Rome motel.
Rome law enforcement was able to arrest the two Oct. 19.
“Through interviews and investigation, a third person was also arrested,” Newsome said, referring to Wofford who was arrested Oct. 22.
Newsome said evidence suggests Watson and Brett were involved in both robberies while Wofford was involved only the Marathon robbery.
