Police Say Lilly Belfield Admitted Driving in Fatal Crash That Killed WashU PhD Student Kennedy Reed

The death of 26-year-old Washington University doctoral student Kennedy Reed has taken a new turn as prosecutors and police pursue charges against Lilly Belfield, 22, while her attorney continues to dispute who was behind the wheel during the fatal St. Louis crash.

Reed was killed on August 4, 2026, when her vehicle was struck near Dr. Martin Luther King Drive and North Euclid Avenue in St. Louis. Reed was entering her fourth year as a Ph.D. candidate at Washington University School of Medicine, where she studied molecular microbiology and microbial pathogenesis.

According to a police probable cause statement, Belfield was driving a BMW with three other people inside when she allegedly traveled at a high rate of speed while intoxicated. Investigators say she illegally passed another vehicle in a left-turn-only lane before running a stop sign at the intersection and striking Reed’s Mazda. Reed died from her injuries, while three people in Belfield’s vehicle were injured.

Police also stated that Belfield admitted after the crash that she had been driving the BMW and that she was intoxicated. That account is central to the charges now filed against her.

But the defense has offered a sharply different account. Attorney David Rosener has maintained that Belfield was a passenger rather than the driver. He previously said he knew who he believed was actually driving but wanted to verify the information before providing the person’s identity to authorities. He has also questioned the police version of events.

Belfield was arrested in September and charged with DWI resulting in the death of another person, first-degree involuntary manslaughter and three counts of second-degree assault. The assault charges stem from injuries suffered by the three other people in the BMW.

At her initial court appearance on September 18, a judge denied bond, leaving Belfield in custody as the case moves forward. Her defense had argued that she was not a flight risk and should be released while the proceedings continued.

While the legal dispute continues, Reed’s family, friends and academic community have focused on the life she was building before the crash. Washington University described her as a promising early-career scientist remembered for her kindness, quiet strength and commitment to academic excellence. Her research examined how microbes could contribute to the progression of skin cancer.

Reed had earned a chemistry degree from Alcorn State University in 2022 before beginning her doctoral studies at WashU in 2023. She was also involved in mentoring and programs designed to help students pursue careers in science. Washington University has established the Kennedy Reed Memorial Summer Program Scholarship to support undergraduate researchers from Alcorn State.

For now, the question of who was driving the BMW remains a central issue in the case. Police and prosecutors are proceeding on the basis of their investigation, while Belfield’s attorney continues to challenge that account. The charges are allegations, and Belfield is presumed innocent unless proven guilty in court.
