Clayton County police say 49-year-old Sandra Barnett was kidnapped by Lisa Brown at her Ellenwood home on Wednesday afternoon.

It all began Wednesday afternoon when neighbors of Barnett said they spotted a black Dodge Durango outside of the teacher's home. The neighbors became suspicious because Barnett had recently replaced the lock on her gate to her backyard after believing that someone had tampered with the latch.

Clayton County police said they believe that the girlfriend of Barnett's husband was the kidnapper.

According to the Carroll County Sheriff's Office, deputies spotted the Durango around noon on Thursday at a truck stop on I-20 near the Waco exit, and a chase ensued.

The driver led officers heading west on Interstate 20 through Carroll and Haralson counties. When the chase crossed state lines, the Alabama State Patrol joined in.

The chase continued to mile marker 208 where the vehicle stopped suddenly while being pursued. According to Clayton County authorities, the suspect reached into the back of the car, retrieved a gun and shot Barnett before turning the gun on herself.

When Alabama troopers approached the car, they found the two women dead.

Officials said that officers did not fire their weapons nor were they fired upon.

The suspect has not been named yet.

The Alabama Bureau of Investigation has taken over the case.
