Javier Abraham Quiroz, 24, was fatally shot at an apartment complex on East Fort Lowell Road in Tucson on March 25, 2018. Police were called about 2:00 a.m. after a woman outside the apartment said her boyfriend had forced his way in. Inside the unit officers found Quiroz with gunshot injuries.

Investigators say the boyfriend, identified as 20-year-old David Turner, was found in the complex parking lot, taken into custody without incident, and a handgun was recovered. Detectives report Turner learned his girlfriend was visiting Quiroz, kicked in the door, entered and shot Quiroz multiple times, then threatened the woman with the weapon until she escaped and got help. Turner was booked on first-degree murder, aggravated assault and kidnapping.

Quiroz was a biomedical engineering student at the University of Arizona and is survived by his parents and sisters. Does anyone have information about Javier’s last known activities or witnessed the events that night?
