Nine wounded in Tucson shooting; suspect shot by officers

Nine people were injured in a shooting in downtown Tucson, Arizona, early Sunday before police officers shot the suspected gunman, authorities said.

The incident unfolded at about 2 a.m. local time when Tucson police officers on patrol heard gunfire and immediately ran toward the sound, police spokesperson Frank Magos said during a news conference.

CBS News reported officers encountered an adult male suspected of carrying out the shooting and repeatedly ordered him to comply before one officer opened fire, striking the suspect.

Victims and suspect taken to hospital

All nine victims, along with the suspect, received emergency medical treatment at the scene before being transported to nearby hospitals.

Magos said many of the victims suffered gunshot wounds to their extremities and were taken to hospital in critical condition. Authorities confirmed that everyone injured in the shooting was an adult but did not release any identities.

The suspect also remained in hospital with life-threatening injuries.

Investigation underway into Tucson shooting

Police said the suspect's identity is known to investigators but has not been made public.

Authorities have not disclosed a possible motive, and officials said the crime scene spans a large area in downtown Tucson.

The Pima County Sheriff's Office will lead the criminal investigation, while the Tucson Police Department will conduct an internal administrative review of the officer-involved shooting. Police said all responding officers were equipped with body cameras.

Magos warned that the investigation is expected to take considerable time and declined to confirm whether the suspect was responsible for shooting all nine victims or how many officers discharged their weapons.
