Carlos Alberto Luque-Cadena, 15, was fatally shot the evening of Saturday, January 28, 2023, behind the Walmart on Wetmore Road in Tucson. The shooting took place during a physical altercation; investigators describe the circumstances as part of an active investigation but have not released a complete chronology of events.

Days earlier, law enforcement had identified Carlos as a participant in a separate homicide that killed 32-year-old Terrance R. Ross, but Carlos was not formally charged in that case before he was killed. The Tucson Police Department has released images of armed individuals who may be connected to the altercation and is asking the public for help identifying them. No arrests or named suspects have been announced.

If anyone saw the fight behind the Wetmore Road Walmart that night or has information about the armed individuals in the released images, please contact the Tucson Police Department.
