Seidah Muhammad Vaughn

A woman is accused of fatally shooting her lesbian partner in their Cedar Hill home in 2008.

Seidah Muhammad Vaughn, a teacher, was arrested Monday at Douglass High School in Oklahoma City, according to The Oklahoman. Vaughn is charged with first-degree murder.

Vaughn’s partner, Judith Marie Bell, was fatally shot on Feb. 29, 2008, in the bedroom of her home in the suburb just south of Dallas.

Vaughn told police an intruder shot Bell, but there were no signs of forced entry at the home.

Bell had been a special education teacher. Vaughn began teaching in Oklahoma City last year.
