TUCSON, Ariz. (KOLD News 13) - Authorities are further investigating a homicide that occurred yesterday just before 8 p.m. at a residence in Tucson’s South Side.
On August 10, 2020, an adult female called 911 to report that her fiancé, 28-year-old Marco Orantez, had been shot outside of a residence in the 1600 block of West Ajo Way.
The woman was driving Orantez to Banner University Medical Center (South) and told authorities there were additional victims left at the scene. Officers immediately responded to both the hospital and the residence, but no additional victims were found at the crime scene.
Shortly after arriving at the hospital, Orantez was pronounced deceased.
During investigations, officers were advised about a second gunshot victim arriving at St. Mary’s Hospital. The victim, an adult male, was transported to Banner University Medical Center (Main) with life-threatening injuries.
While being briefed on the incident, a third gunshot victim arrived at St. Mary’s Hospital. The adult male victim was treated for serious, but non-life-threatening injuries. Officers at the hospital then learned of a fourth adult male victim who was also there but was not injured.
After speaking with witnesses and two of the victims, detectives were able to determine the incident started over a neighbor dispute.
Orantez and several of his friends were working on a car in front of his residence. Orantez’ neighbor, 34-year-old Luis Tapia Jr., was upset about where Orantez and his friends parked the car and an argument ensued.
Reports say Tapia retrieved a handgun from his residence and began shooting at Orantez and his friends. Three of the four victims were struck by gunfire. Officers were able to locate and detain the suspect at his residence.
Tapia was interviewed by detectives and a search warrant was obtained for his home. Detectives found the handgun they believe was used, along with an illegally modified shotgun.
After processing the scene and conducting interviews, detectives arrested and booked Tapia into the Pima County Jail on one count of First-Degree Murder, three counts of Aggravated Assault w/a Deadly Weapon and one count of Weapons Misconduct.
Detectives are asking for anyone with information to come forward. You can remain anonymous by calling 88-CRIME.
