Alex James Barnett, a 33-year-old man, is currently at large and wanted by law enforcement in connection with the murder of Carlos Ramirez, a Tucson police recruit. Authorities have issued an arrest warrant for Barnett and declared him armed and dangerous, triggering a statewide Blue Alert in Arizona. Barnett is described as 6 feet 2 inches tall, weighing approximately 315 pounds, with a bald head, brown eyes, and multiple tattoos. He was last seen wearing a red shirt and a black motorcycle vest. Investigators are also searching for a maroon 2020 Harley-Davidson motorcycle, model FLHXS, with Arizona license plate D4A656. The incident involving Ramirez occurred at a residence west of Tucson, where Ramirez was fatally shot and his fiancée, a Pima County corrections officer, was injured. The Pima County Sheriff’s Office is actively searching for Barnett and two additional suspects linked to the homicide. While Barnett is the subject of intense public interest due to his connection to the separate, ongoing disappearance of 84-year-old Nancy Guthrie, authorities have not confirmed any link between Barnett and the Guthrie case. Social media speculation has arisen comparing Barnett to the unidentified suspect in the Guthrie investigation, known online as 'Porch Guy,' but investigators emphasize that the two cases are being handled separately and no official connection has been established. The Nancy Guthrie investigation, led by the Pima County Sheriff’s Office and the FBI, remains active with no arrests made. The public is urged to contact law enforcement with any information regarding Barnett’s whereabouts rather than attempting to approach him.
