Richard Ulibarri, 49, was shot and killed in the early morning hours of July 18, 2020, at a mobile home park on the south side of Tucson near 4444 E. Benson Highway. Deputies arrived about 3:30 a.m. after reports of gunfire and found Ulibarri with traumatic injuries; he was pronounced dead at the scene. A second person was wounded but survived.

Witnesses said the shooters ran on foot from the scene. Homicide detectives interviewed numerous people and within weeks identified and arrested five suspects: 20-year-old Gabriella Acosta, 18-year-old Noah Arguellez, 20-year-old Nea Jones, 20-year-old Ariel Monarrez, and 20-year-old Robert Yslava-Varela. All five were booked into the Pima County Adult Detention Complex and face multiple felony counts, including first-degree murder, in connection with Ulibarri’s death.

Does anyone have information about that night or recall seeing activity around the mobile home park on Benson Highway?
