Detroit — Police are asking for the public's help finding a fifth suspect in the February murder of a 64-year-old man on Detroit's west side.
Samuel Johnson, 33, is wanted in connection to the Feb. 6 homicide, which happened at about 9:10 p.m. in the 14000 block of LaSalle Boulevard south of Oakman and east of Lindwood Street, according to police.
Anyone with information about Johnson's whereabouts should call the Detroit Police Department’s Homicide Unit at (313) 596-2260 or Crime Stoppers of Michigan at 1 (800) SPEAK-UP.
Authorities said Johnson is described as being 5-feet-11, 220 pounds with a dark complexion, a mustache and goatee. He may be wearing a short, braided hair style and eyeglasses.
