The investigation began early on May 6, 2022, when Tampa police responded to a 911 call about an unresponsive person in a field. They found Nilexia Alexander's body near the road, along with shell casings and a phone charger, but her cell phone was missing. That phone later became key evidence. GPS data showed it had traveled in a dark-colored sedan, later linked to Ronny Walker. Surveillance footage captured a vehicle matching that description near the scene with its headlights off shortly before gunfire was detected by ShotSpotter, a gunshot-detection system, according to court documents. The same car was later seen on security cameras at Tampa General Hospital. Inside Walker's black Ford Fusion, investigators found blood traces that DNA testing confirmed belonged to both Nilexia and Walker. A third person who had been in the vehicle was also detected and identified as Robert Creed. Detectives then found surveillance video showing Nilexia getting into Walker's vehicle near his home, just minutes before she was killed. "To take a baby's life, you'd have to be heartless. I would never have the closure of why he took my daughter's life at 14," Ashley Alexander said in an interview on the first anniversary of her daughter's murder. https://www.wtsp.com/article/news/crime/ronny-walker-tampa-murder-nilexia-alexander-trial-live-stream/67-5c62cae2-3bd2-4e42-9493-1f81e65a22e3
