A 17-year-old stole a handgun and used the weapon during an attempted robbery Saturday night before he was accidentally shot by a juvenile, according to La Crosse police.

A man sitting in his car parked outside Vick’s Bar, 3749 Mormon Coulee Road, said a male approached the window with a bandana covering his face and demanded money at gunpoint about 9:25 p.m., according to the complaint filed in La Crosse County Circuit Court. The victim chased the subject before returning to the bar and calling police.

A handgun was reported stolen from a car parked nearby.

Police identified the suspect as Mackey Drake, who fled after the robbery to 3072 S. 23rd St., where a juvenile who thought the gun was fake shot him in the shoulder, the complaint stated. The juvenile also told investigators she witnessed Drake try to rob the driver.

Officers found Drake, who does not have a permanent address, about 11:30 p.m. at Subway, 3810 Mormon Coulee Road. He said he found the gun and brought it to 3072 S. 23rd St.

Drake admitted that he was involved in the robbery, but told investigators he used his cellphone to look like a firearm, according to the complaint.

Prosecutors charged Drake, who is on juvenile supervision, with attempted armed robbery with use of force and theft. He is jailed on a $10,000 cash bond.

Police investigated 18 guns calls so far this year, compared to seven calls Jan. 1 to Nov. 13, 2010.
