Over two days last year, two Washington men took part in the carjacking of a cabdriver and then robbed four women in four separate incidents in Southeast Washington, authorities said. The two men, identified as Jarrell Bell, 22, and Jared Farmer, 23, pleaded guilty Friday in connection with the incidents, the U.S. attorney's office said. In each of the incidents, one man carried a metal rod and the other a BB gun that looked like a handgun, federal prosecutors said. It was not clear who carried which in each of the robberies. According to prosecutors, Bell, Farmer and a third man robbed a cabdriver in the 800 block of Bellevue Circle before 1 a.m. April 24, 2011, and drove off in his vehicle. A few hours later, Bell and Farmer robbed a woman who was waiting for a bus in the 4200 block of Sixth Street, prosecutors said. About 4:30 a.m. April 25, 2011, a woman walked past Bell and Farmer, who were leaning against a fence in the 1500 block of Alabama Avenue, prosecutors said. After the woman passed, they put on masks, approached her and demanded her purse. Prosecutors said Bell struck the woman with the rod when she tried to run. About two hours later, they took the purse of a woman at a bus stop near First Street and Mississippi Avenue, and then took the purse of a woman who saw that robbery and tried to run, prosecutors said. The prosecutor's office said they were each charged with armed robbery. Authorities said the third man who participated in the carjacking is still being sought.
