Sandra Barnett, 59, died after a wild chase that ended in Alabama. Barnett is the wife of former NFL player Buster Barnett, who was drafted by the Buffalo Bills as a tight end in 1981, according to Clayton County police.

Barnett worked as a special needs teacher for McNair Middle School in DeKalb County.

Channel 2’s Amy Napier Viteri spoke to a friend of Barnett’s who was on the phone with her when the attacker showed up.

Ruby Chester said Barnett was home when a woman who had previously been involved with Barnett's husband showed up at her door on Gracewood Park Drive. Over the phone, Chester says she heard the woman demanding Barnett let her in and threatening to kill her.

“She said, ‘Open this door before I kill you. Open this door or you're going to die,’” Chester said.

Chester called 911 and friends went to the home to check on Barnett, including her brother, John Brooks.

Police believe Lisa Brown, a former teacher for Atlanta Public Schools, forced Barnett to leave with her in a black Dodge Durango owned by Barnett's husband.

A friend saw the SUV Brown was driving leave the subdivision, not realizing Barnett was inside.

Investigators put out an alert for the SUV.

Police tracked Brown's cellphone into Alabama and Mississippi.

Wednesday afternoon, deputies with the Carroll County Sheriff's Office spotted the vehicle and chased it into Alabama. Officers said the SUV stopped on Interstate 20 and they saw Brown pull a handgun, shoot Barnett and then shoot and kill herself.

Chester said she had warned her friend about the woman who had been having a relationship with Barnett's husband.

“A couple times, she would see her car parked out in front of her door,” Chester said. “I'm just sad, because it didn't have to happen, and I told her to do something about that woman being so aggressive toward her."

Brooks described his sister as someone who was loved by her friends and students.

“There was no stranger to her anyone who met and talked with her. She always had a smile on her face,” Brooks said.

Police say inside the SUV, they found a receipt and handcuffs recently bought by Brown prior to the kidnapping. They say Brown was on probation for kidnapping her daughter in Texas recently due to a custody dispute.
