On the morning of November 1, 2019, following a Halloween party in St. Louis, 38-year-old Mark Schlemmer was shot while seated in the passenger seat of a car in the 700 block of North 15th Street. The shooting happened about 2:15 a.m. Schlemmer, a Collinsville, Illinois resident and father of two teenage daughters, was with two other people when a vehicle driven by a man later identified as Leron Harris pulled up and blocked them.

His bullet missed the intended target and struck Schlemmer in the head. The driver fled and Harris pursued, later losing control and crashing into parked cars. Schlemmer was taken to a hospital and died of his injuries on November 2, 2019. A witness who owned the car Harris used told police she was told to report the vehicle as stolen and to discard her phone, and the driver of Schlemmer’s car later identified the mask from a photo on Harris’s Instagram.

Does anyone have information about Schlemmer’s movements that night or saw the vehicle involved?
