The Ritenour High School senior died days after classmates named her prom queen.
ST. LOUIS COUNTY, Mo. — A Ritenour High School senior who had recently been crowned prom queen was one of three women killed Friday night in a three-vehicle crash on Lewis and Clark Boulevard, authorities and school officials said.
The crash killed Jordyn “Lunar” Williams, 18, of St. Louis, along with Cherese Fisher, 53, of St. Louis, and Andrea Medina, 28, of Florissant. Missouri State Highway Patrol investigators said the wreck happened at 8:32 p.m. May 1 on southbound Lewis and Clark Boulevard, north of Haviland Drive. The crash left two vehicles overturned or heavily damaged, sent emergency crews to a busy north county road and brought grief counselors to Ritenour High School on Monday.
Investigators said a 2013 Cadillac SRX was traveling south when it sideswiped a 2020 Lexus RX350, also traveling south. The impact pushed the Lexus into the northbound lanes, where it was struck on the right side by a 2013 Toyota Highlander. The Lexus overturned after the collision. The Cadillac left the roadway and struck trees, according to the crash report. Williams was a passenger in the Lexus, which Fisher was driving. Medina was driving the Toyota. “This is a heartbreaking loss for the Ritenour community,” the district said in a message to families, according to local reports.
Christian Hospital EMS personnel pronounced Fisher and Williams dead after the crash, according to the patrol report cited by local outlets. Medina was pronounced dead at 8:43 p.m. The three bodies were taken to the St. Louis County Morgue. All three vehicles had moderate to extensive damage and were towed from the scene. Early reports said the Cadillac driver fled after the crash. A later local report said the driver had been located and taken into custody, though the driver’s name, age, gender and condition had not been released. It was not immediately clear Monday whether charges had been filed.
Williams was remembered as a senior at Ritenour High School and a recent prom queen, a title she received only days before the crash. A friend told First Alert 4 that Williams had been named prom queen the week before she died. The school district confirmed her death and said support was being offered to students and staff. Ritenour High School is in the St. Louis suburb of Overland and serves students from several nearby north county communities. The crash happened less than two weeks before many Missouri seniors were preparing for graduation ceremonies, year-end events and final school days.
The fatal wreck unfolded on a stretch of Lewis and Clark Boulevard, also known in the area as part of Missouri Route 367. The road carries local and regional traffic through north St. Louis County. Patrol investigators said the chain of events began with the Cadillac sideswiping the Lexus in the southbound lanes. The Lexus then crossed into oncoming traffic, where Medina’s northbound Highlander struck it. The report did not say why the Cadillac hit the Lexus or whether speed, impairment or distracted driving were suspected factors. Those details remained unknown Monday as the Highway Patrol continued its investigation.
The crash was investigated by the Missouri State Highway Patrol’s Major Crash Investigation Unit. The fatality report listed Master Sgt. J. Cox and Cpl. A. Smith as investigators, with other patrol personnel assisting at the scene. Authorities had not released a full account of what happened after the Cadillac hit the trees. Local reporting said the driver was later taken into custody, but officials had not announced charges or a court date. Investigators were expected to review roadway evidence, vehicle damage, witness statements and any available surveillance or traffic camera footage from the area.
At Ritenour High School, the deaths landed at the start of a school week. Grief counselors were made available Monday for students and staff members coping with Williams’ death. The district did not release details about funeral plans. Friends and classmates shared tributes online, describing Williams by her nickname, Lunar, and posting photos from recent school events. The public remembrances focused on the sharp turn from celebration to loss, with prom memories from the previous week followed by news of the crash that killed her, Fisher and Medina.
By Monday, the Missouri State Highway Patrol was still investigating the three-vehicle crash. Authorities had not released charging information, and the next public step is expected to come through patrol updates or court records if prosecutors file a case.
