On the Sunday May 6, 2018 at about 1:36pm the South Milwaukee Police Department received a 911 call from Al’s Service Center located in the 1100 block of Marquette Avenue reporting that they had just been robbed. A white male entered the service center, displayed a semi-automatic hand gun, demanded money from the owner and fled in an unknown direction. Suspect has not been located at this time.
