Osvaldo Raul Vargas was 35 when he was shot in a drive-by attack outside his Tucson home on the evening of January 14, 2014. He suffered a critical gunshot wound to the head, was taken to the University Medical Center, and died of his injuries six days later on January 20, 2014.

Vargas was the family’s sole provider; his wife Brenda and their five children were inside the house during the shooting and were not physically harmed. He was described as a loving husband to his high school sweetheart and a devoted father to four daughters and a four-year-old son. A GoFundMe was created to help the family, and Vargas became an organ donor.

The Tucson Police Department opened a homicide investigation, but no arrests or public suspect identifications have been reported and the case remains unsolved. If anyone saw the drive-by or has information about that evening, can you share what you know with investigators?
