On the night of May 30–31, 2017, 22-year-old Dylan Steffen was fatally shot while walking with a friend near 2nd Street and Lapham Boulevard in Milwaukee. The pair had been out for a comedy show and bar-hopping when a man stepped out of a school parking lot, put Steffen’s friend in a headlock and brandished a gun, demanding the friend surrender his belongings. The friend escaped the hold and both ran; a single gunshot struck Steffen in the back. He was still alive when police arrived but died at a hospital from that wound.

Surveillance captured a distinctive white four-door Chevrolet Impala with a dark front bumper and quarter panel damage arriving just before the shooting and leaving afterward. A tip from a television viewer led police to the car’s owner, who said he had lent the vehicle to an acquaintance, Jermichael Carroll, and that Carroll had taken it that evening and returned after midnight. Steffen’s friend identified Carroll in a photo lineup, and police arrested him. In November 2019 a jury found Carroll, then 32, guilty of first-degree reckless homicide, use of a dangerous weapon, attempted armed robbery, and being a felon in possession of a firearm.

Did anyone in Milwaukee see the Impala or the men near 2nd Street and Lapham Boulevard that night?
