Summary based on the NamUs case record (MP81952) and 1 other source
In the early summer of 2021, a 32-year-old woman named Sandra Mai St John, also known to some as Lexi, vanished from Lafayette, Tennessee. She was last seen on June 6th of that year. At the time of her disappearance, Sandra was described as having pink hair and brown eyes. She has distinctive tattoos, including flowers on her upper chest and a cross-like tattoo on her left hand, situated between her thumb and index finger. The circumstances surrounding her last known moments remain unclear, and she has not been seen or heard from since that day.

The details that have emerged since Sandra's disappearance paint a concerning picture. It is understood that she was last seen somewhere between Lafayette and Lebanon, Tennessee. According to her sister, Sandra had been dropped off at the residence of a man named Jose Guerrero. Disturbingly, an individual who went to pick her up from that location was allegedly shot at in the driveway and chased off by Guerrero. Following this incident, Sandra was never seen again. The situation grew more alarming when it was discovered that Guerrero's car and a camper she was in that day were both found burned.

The investigation into Sandra St John's disappearance has been fraught with challenges. Law enforcement has identified Jose Guerrero as a person of interest who is wanted for questioning. However, it is believed that he may have fled the country, possibly to Mexico, which complicates the efforts to locate him and gather more information. Adding another layer of complexity to the case, Guerrero's girlfriend has also been reported as missing. It remains unknown whether she is a victim or is in hiding. The case is an active investigation, with family and law enforcement seeking any information that could lead to answers about what happened to Sandra. An overview of the case suggests a deeply troubling scenario involving violence and the subsequent disappearance of a key person of interest, leaving a family desperate for resolution and the whereabouts of their loved one unknown.
