Gunman's actions took police on a hunt across 3 locations in the area

TUCSON, Ariz. (KYMA, KECY/CNN) - The Tucson Police Department (TPD) has identified the suspect in Sunday's deadly shooting rampage as Leslie Scarlett, 35, in a press conference Monday evening.

Police Chief Chris Magnus broke the news, revealing that the 35-year-old's criminal record discloses he is a "prohibited processor" due to serving six years in prison for an armed robbery conviction.

"This is both a highly tragic, really horrific incident with many unknowns at this time," Magnus expressed.

Scarlett is currently hospitalized and described as being in "extremely critical condition." The chief of police said that the gunman's official charges have not yet been determined.

The TPD also identified the victim as Corey Saunders, 44, whom died at the scene. Saunders is survived by his 11-year-old son whom witnessed the attack.

"He shot at firefighters and neighbors alike, basically anyone who was trying to help," Magnus commented.

Police also identified the cop whom witnessed Scarlett getting away, and then proceeded to exchange gunfire with the suspect, as Officer Danny Leone. Leone is an eight-year TPD veteran.

Magnus clarified that a motive has not yet been established for Scarlett's actions.

"It is not clear what his intentions were, because he was shooting at people, you know, both neighbors and firefighters, so his intentions remain unclear," the chief of police said. He added that officers are also examining whether Sunday's fire is connected to a fire earlier this year in which Scarlett's wife burned to death.
