Alyssa Wilson, a 17-year-old senior at McCluer North High School, was a vibrant and beloved young woman with a bright future ahead of her. Remembered for her infectious smile and caring nature, Alyssa was a student-athlete, an office aide at her school, and was making plans to attend college the following year. She was just 60 days away from her 18th birthday, and her family was excitedly planning their first family vacation to Disney World to celebrate, a trip where Alyssa hoped to meet her
favorite character, Princess Tiana. Her father, Robert Hickman, described her as being "excited about her life, excited about her future."
On the evening of October 14, 2026, Alyssa was driving her red Buick Encore southbound on Interstate 170 in Overland, Missouri, a suburb northwest of St. Louis. Around 7:20 p.m., she was on her way to meet a friend at the St. Louis Zoo for its popular Halloween event, "Boo at the Zoo." As she drove near Midland Boulevard, she passed a white Buick Enclave that was parked on the right shoulder of the highway. A person stepped out of the passenger side of the parked SUV and fired a single shot. The bullet struck the rear of Alyssa's vehicle, hitting her in the back and chest. Incapacitated by the gunfire, she lost control of her car, which then crashed into the concrete median wall. Emergency responders rushed her to Barnes-Jewish Hospital, but she was pronounced dead from her injuries.
The investigation was taken over by the Major Case Squad of Greater St. Louis, which quickly pieced together evidence from the scene. Highway surveillance video captured the white Buick Enclave pulling over, the person exiting to fire the shot, and the vehicle then turning off its hazard lights and driving away. Using the video and automated license plate readers, investigators traced the SUV, which had out-of-state plates, to a hotel in Caseyville, Illinois, about 12 miles from the scene. They placed the vehicle under surveillance.
Two days after the shooting, on October 16, investigators arrested Willie Herndon, 43, and his wife, Taiya Herndon, 45, a couple from Arlington, Texas, as they left the hotel. A search of their hotel room uncovered a firearm and other evidence. Authorities determined there was no connection whatsoever between the Herndons and Alyssa Wilson, describing the deadly shooting as a senseless, random act of violence. Investigators also linked the suspects to another highway shooting that had occurred three days earlier on Interstate 55, where a shell casing from the same manufacturer was found.
Willie Herndon was charged with first-degree murder, armed criminal action, and felon in possession of a firearm. His bond was set at $1 million, cash only. Taiya Herndon was charged with hindering prosecution for allegedly driving her husband to Illinois after the shooting. Her bond was set at $500,000, cash only. During an interview, Willie Herndon reportedly provided investigators with details about his involvement in the incident and information related to other possible ongoing investigations.
Alyssa's father expressed his family's devastation and thanked law enforcement for their swift work in making arrests. "No arrest can bring Alyssa back, but we hope this announcement represents a step toward accountability and justice," said a spokesperson for the Major Case Squad. At a press conference, Hickman tearfully remembered his daughter's excitement for the future that was stolen from her. "This was a senseless act," he said, "and we ask that everyone take a look at yourselves inside and make sure that next time something happens like this, you think before something happens." As of October 2026, the case against the Herndons was proceeding through the court system.
