A 49-year-old man remains in critical condition at a Tucson hospital following a violent stabbing incident that occurred Tuesday afternoon. Law enforcement officials are actively searching for a 30-year-old male suspect who fled the scene on foot and remains at large. The attack took place in the 4400 block of East Camino Principal, located just south of Sierra Vista in Cochise County. Upon arrival at approximately 3:19 p.m., deputies and emergency medical personnel discovered the victim suffering from apparent stab wounds at his residence. Investigators quickly determined that a 30-year-old man was responsible for the assault before he escaped the immediate area. Due to the severity of his injuries, the victim was initially transported to Canyon Vista Medical Center in Sierra Vista but was subsequently airlifted to a medical facility in Tucson for advanced surgical care and treatment. At this time, the Cochise County Sheriff's Office has not released the suspect's full name or a physical description. The investigation remains in its early stages, with deputies canvassing the neighborhood and reviewing available evidence. Authorities are asking anyone who may have witnessed the incident, or who has information regarding the suspect's whereabouts, to come forward immediately. The sheriff's office has established a dedicated tip line for the public to share any relevant details that could assist in locating the suspect. Additional information regarding the suspect's identity and the ongoing investigation will be provided as it becomes available. Residents are advised to remain vigilant and report any suspicious activity to local law enforcement. This is a developing story, and updates will be issued as more facts are confirmed by investigators.
