A Milwaukee teen charged in a string of armed robberies last week told police he was trying to do as many crimes as he could before he turned 18 on Sept. 11. Rocarldo Chalmers is one of five suspects charged Wednesday in a dizzying spree of armed stickups and car jackings that ended only after a high-speed chase. Chalmers faces 10 felonies, including armed robbery, car theft and fleeing.

Isiah Deshawn Thomas, 18, is charged with five counts, Anthony Griffis, 17, with two. Two juveniles have been charged in Children's Court. As many as three other suspects remain at large.

Things got rolling about 6:30 p.m. Sept. 9 in the 1800 block of Fond du Lac Ave. Chalmers and a juvenile, armed with a small sledgehammer, demanded the keys to a gray Jeep Cherokee from the owner. The victim noticed three more males watching from a silver Dodge Durango (stolen the previous night). One had a gun. The victim gave up his keys but refused to give up his phone.

Over the next 26 hours, the suspects stole cars from their drivers at gunpoint and robbed five pedestrians from the east side to Wauwatosa. One victim was struck, and shots were fired at another. Cars and other stolen property were found abandoned around the city.

At 10:35 p.m., a woman was robbed of her silver 2014 Hyundai as she was pulling into her garage in the 3800 block of N. 44th St. About an hour later, another woman was robbed at gunpoint of her silver 2010 Honda in the 7300 block of W. Potomac Ave. About 1 a.m., the car was seen near N. Bremen and W. Locust streets but fled from police.
