The Pima County Sheriff's Department, in coordination with the Arizona Department of Public Safety, has issued a Blue Alert for 33-year-old Alex James Barnett. Barnett is wanted in connection with the murder of Carlos Ramirez, a Tucson police recruit who was shot and killed inside his home on Wednesday, August 20. Ramirez's 23-year-old fiancée, a corrections officer with the Pima County Sheriff's Department, was also shot during the incident but is expected to recover. Authorities have released surveillance video identifying two additional possible suspects. One individual was seen with Barnett at a Shell station on Valencia Road, while another was observed exiting a vehicle believed to be involved near Palo Verde Road. Barnett has a documented criminal history that includes charges of child abuse, theft, and unlawful imprisonment. Law enforcement officials describe him as armed and dangerous, urging the public not to approach him under any circumstances. The Blue Alert, a rare measure reserved for situations where a law enforcement officer has been killed or attacked and the suspect poses an imminent threat to the public, highlights the urgency of the manhunt. Bart Graves, a spokesman for the Arizona Department of Public Safety, emphasized the importance of public assistance in locating Barnett to prevent further danger. Former police officer Josh Logan of Guardian Training & Consulting also noted that fugitives often become more desperate as time passes, making rapid apprehension critical for community safety. The incident has prompted a statewide response, with phones across Arizona receiving alerts on the night of August 20. Investigators are actively reviewing evidence and have identified multiple locations of interest. The public is urged to remain vigilant and report any information that could lead to the suspect's capture. Tips can be submitted by calling 911 for immediate emergencies or dialing 88-CRIME to leave anonymous information. The investigation remains ongoing as authorities work to bring all individuals involved in the shooting to justice.
