CEDAR HILL (AP/CBSDFW.COM) – An Oklahoma City high school teacher has been arrested on a murder warrant in connection with the 2008 fatal shooting of her partner in Cedar Hill.

Seidah Vaughn was taken into custody Monday afternoon by police officers from Oklahoma City and Cedar Hill at the high school she teaches at in Oklahoma City.

Vaughn is being held without bail.

Judith Bell, a special education teacher at Permenter Middle School in Cedar Hill, was fatally shot in her home in Feburary 2008. Authorities say Vaughn, identified as Bell’s partner, told police an intruder had shot Bell but investigators found no signs of forced entry into the home.

In a statement, Cedar Hill Police Chief Steve Rhodes said his detectives “worked diligently for nearly three years to solve this crime. We are pleased to be able to file charges and we are confident they will result in a conviction, giving family and friends closure on this tragic situation.”

Cedar Hill Police say new evidence in the case led to the arrest.  They say they have spent the past 33 months working on the case, conducting investigations in three states with the assistance of the Texas Department of Public Safety, the Oklahoma City Police Department, and the U.S. Army Criminal Investigation Command.
