According Sgt. Maggie Cox, undercover officers were conducting surveillance on Ruiz.

Det. Luis Samudio said Ruiz was a suspect in the Aug. 17 killing of 38-year-old Miguel A. Valenzuela.

Police say Ruiz noticed that he was being followed and took off.

"The suspect refused to stop and fled from police at a high rate of speed," according to a statement from Phoenix police.

Police say Ruiz then rammed an undercover police car, disabling his vehicle.

Next, Cox said Ruiz got out of his vehicle, armed with a handgun, and tried to carjack a passing driver.

An officer intervened in the carjacking, "using his vehicle, which caused the suspect to fall to the ground."

Police say Ruiz raised and fired his gun at an approaching police officer, but did not strike him. The officer then fired his service weapon, striking the suspect.

Ruiz was taken to a local hospital where he was later pronounced dead.

Nearby Tolleson Union High School was placed on a "lock-out" before the start of the school day as a precaution. 

During a "lock-out" no one is allowed on campus. Tolleson Union High School principal Felipe Mandurraga said the lock-out was lifted after the situation was cleared at 8:30 a.m.

The principal sent the following email to parents this morning: 

Good morning Tolleson,

This morning at approx. 8:20 a.m. we received information from our School Resource Officer that a police incident was occurring in close proximity to the Tolleson High School campus. He advised us to go into a 'Lockout' as a precaution.
Site Administration immediately initiated our Lockout procedure.Our students and staff did an incredible job of following procedures that were just practiced on Tuesday.

Reminder to Parents/Family: during a lockout or lockdown nobody will be permitted on campus.
At approx. 8:30 a.m. our School Resource Officer received information that the incident was clear and there was no longer a potential threat to our campus.
School safety continues to be our top priority. If you have any questions or concerns please let me know.

Thank you,
