An armed robbery suspect was killed and another was injured in a shooting involving a Pinal County Sheriff's deputy Monday morning. 

The incident started around 6:30 a.m. when two armed suspects entered the M Passion Adult Boutique in Picacho Peak and tied up a female employee in the back room, Tim Gaffney, a Pinal County Sheriff's Office spokesman said in a news release.

The woman escaped and called 911 as the suspects fled the business, the release said. 

The suspects left with the safe. 

A few minutes later deputies saw an Audi car in the area of the robbery speeding westbound on Interstate 10 and tried to stop the vehicle, the release said. 

The Audi failed to stop and deputies began pursuing the vehicle. During the pursuit, the Audi reached up to 120 miles per hour. 

The Audi exited I-10 onto Highway 87, pulled into a dirt field and collided with the deputy's vehicle, the release said. 

Two men exited the Audi and begin firing at the deputy who shot back. 

One suspect was pronounced dead at the scene and the other man was shot in the arm and leg. 

The injured man tried to flee but was caught by the deputy. 

The man fought with the deputy as he tried to place him under arrest, the release said. 

The man was taken into custody and taken to the hospital. 

The deputy, who is a seven-year veteran of the department, was not injured. 

Detectives are investigating the robbery and shooting. 

The names of the suspects, who are in their 30s, have not been released.
