Man charged with homicide after minor accident escalates to fatal shooting

A minor traffic collision near a downtown concert escalated into gunfire that left a woman dead and a suspect in custody.

MILWAUKEE, WI — A 26-year-old Glendale man faces a first-degree intentional homicide charge following a fatal shooting triggered by a minor car accident in the Deer District last Saturday night as crowds gathered for nearby events.

The criminal complaint against Demetris Riley describes a rapid escalation from a fender-bender to a deadly confrontation on Feb. 28. Authorities say the incident occurred near the intersection of Vel R. Phillips Avenue and State Street, a busy corridor for pedestrian traffic during downtown concerts. Riley turned himself in to Milwaukee police on Monday, March 2, accompanied by an attorney, after investigators used surveillance and dashcam footage to identify the vehicle involved in the shooting of 47-year-old Sharita Barber.

The confrontation began just after 11:30 p.m. as attendees were leaving a concert at Fiserv Forum and other nearby venues. According to the complaint, Riley told investigators he was preparing to leave when Barber backed into his vehicle. A second person in Riley’s car reportedly stepped out and began shouting at Barber. When Barber eventually exited her car, Riley claimed she was yelling and bumped into him. Witnesses told police they heard an argument followed by several gunshots in quick succession near the intersection. A traveling registered nurse who had just left Turner Hall attempted to perform CPR on Barber until emergency responders arrived, but she was pronounced dead at the scene.

Police recovered a .22 caliber handgun with an extended magazine and six fired cartridge casings at the scene. While Riley initially told police the victim had pointed a gun at him and that his companion fired the first shots to defend him, he admitted to taking the firearm and shooting Barber again because he believed she was reaching for her own weapon. Detectives noted that while a handgun was found near Barber, forensic analysis determined the six casings found on the street did not match that specific weapon. Riley also admitted to driving over the victim as he fled the area, stating she was laying in his path and he feared for his safety.

The shooting occurred during a particularly high-traffic night for the Deer District, which included a Milwaukee Admirals game, a Christian music concert at Fiserv Forum, and an opening weekend event at a nearby live music venue. Milwaukee police utilized a variety of digital evidence to piece together the timeline, including footage from a city pole camera, a Lyft driver’s dash camera, and video captured by a citizen witness. These records allowed investigators to track the suspect’s vehicle as it moved through downtown. Public records indicate that while Barber was found with a firearm, the investigation focused on the multiple shots fired by Riley after he allegedly disarmed his companion and continued the engagement.

Riley made his initial appearance in Milwaukee County court on Friday, March 6. During the proceeding, a judge set cash bail and scheduled a preliminary hearing to determine if there is enough evidence to move the case to trial. Prosecutors have charged Riley with one count of first-degree intentional homicide, a felony that carries a mandatory life sentence if convicted. The second person involved in the initial confrontation has been identified by police, though it remains unclear if they will face separate charges related to the initial shots fired before Riley took control of the weapon.

Family members and community advocates have expressed shock at the violence stemming from a routine traffic disagreement. “You want to be able to come down here and unite as one… but when things like that happen it’s tough,” said a local resident who witnessed the heavy police presence on Saturday. Investigators are still looking for additional witnesses who may have been caught in the post-concert traffic and might have more dashcam footage of the white sedan Riley was driving. The intersection remained closed for several hours on the night of the shooting as forensic teams marked evidence near the blood-stained pavement.

The Milwaukee County District Attorney’s Office continues to review evidence as the case moves toward a scheduled court hearing later this month. Riley remains in custody at the Milwaukee County Jail.
