On August 22, 2020, just before 11:00 a.m. officers from Operations Division South were directed to a mobile home complex in the 3100 block of East Behan Street for a possible location of an embezzled vehicle. The vehicle was reported as embezzled from a local rental car business and was equipped with a GPS tracking system which led officers to that location. Officers spotted the same vehicle driving earlier in the day, but the driver sped away from officers when they attempted to stop the vehicle. When the first officer (Officer Calderon) arrived on Behan Street, he noticed the vehicle parked with several occupants inside. As he approached, an adult female exited the vehicle and fled on foot. An adult male then exited from the driver’s seat and fired a shot at Officer Calderon. The suspect/shooter then fled on foot into the mobile home complex as two other suspects exited the vehicle and fled. Additional officers responded to the scene, including several deputies from the Pima County Sheriff’s Department that were in the area. Deputies were able to locate and detain the female that fled from the vehicle. As officers began searching for the suspect/shooter and the other suspects involved, additional shots from the original suspect/shooter were fired toward Ofc Calderon and Officer Calderon returned fire with his handgun. The suspect/shooter continued running through the complex and eventually ran toward a second officer on scene (Officer Jahnke). The suspect/shooter then pointed a gun at Officer Jahnke and Officer Jahnke discharged his firearm, striking the suspect/shooter multiple times. Officers immediately began rendering aid to that suspect utilizing their Individual First-Aid Kits (IFAK). Tucson Fire took over medical treatment and transported the
suspect to Banner University Medical Center with life threatening injuries. A male juvenile teenager who fled from the vehicle was also located and detained in the area. The fourth suspect involved (unknown male) is still outstanding. Detectives with the Tucson Police Violent Crimes Section responded to continue the investigation. After processing the scene, conducting interviews and reviewing body worn camera footage, it was determined that Officer Calderon and Officer Jahnke were the only officers who discharged a firearm during the shooting. It appears that only one of the four suspects involved fired shots. That suspect was armed with an AR .22cal pistol and a .40cal handgun. Pictures of both of those weapons are attached below. The suspect/shooter has been identified and is still receiving medical treatment at the
hospital. Charges for that suspect are pending. The two detained suspects were identified but have not been charged as of this date.

This is standard protocol in all officer-involved shootings. The officers involved in the shooting were Officer Edward Jahnke, a 7 ½ year veteran of the Tucson Police Department and Officer Jesus Calderon, an officer with almost 2 years of service with the Tucson Police Department.
Thankfully, no officers or other community members were injured during this incident. The investigation is ongoing and additional details will be released as they become available. Anyone with additional information is asked to call 88- CRIME. You can remain anonymous.
