According to authorities, Barnett was on the telephone with a friend when Brown broke into her Ellenwood home around noon-time on Wednesday.

The friend told police she heard 49-year-old Barnett telling the intruder “please not to hurt me”.

Police said Brown forced Barnett into her vehicle and then placed handcuffs, which she had earlier purchased, on her.

Thursday morning, Carroll County authorities spotted a Dodge Durango being driven by Brown, and upon noticing the cops, Brown led them on a chase on Interstate 20 into Alabama.

Police said Brown stopped the SUV in the middle of the interstate at mile marker 208 and shot Barnet, a special needs teacher at McNair Middle School, before turning the gun on herself.

It is believed that Buster Barnett, who played four seasons with the Buffalo Bills from 1981 through 1984, and 46-year-old Brown had been in a relationship for several years.

Buster Barnett was not available to comment.
