PHOENIX (3TV/CBS 5) -- Phoenix police are investigating after officers shot and killed a homicide suspect Friday morning.
That suspect has since been identified as 51-year-old Rene Enrique Ruiz.
The shooting happened just before 8:30 a.m. near 91st Avenue and Van Buren Street.
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:
