Dodge City ? Former Dodge City police officer Chris Tahah has been found guilty of shooting and killing his ex-girlfriend.

A Ford County jury on Thursday convicted Tahah of first-degree murder in the May 5, 2007, slaying of 25-year-old Erin Jones. A sentencing hearing has not been set.

Tahah was arrested May 11 along Interstate 70 in eastern Colorado after being chased in a stolen sport utility vehicle.

He had initially told investigators that he took a .270 caliber rifle to Jones’ home after seeing her at a bar dancing with another man. Tahah said he had talked himself out of shooting Jones and that the rifle went off as he lowered it outside the door.

But Tahah took the stand in his own defense Wednesday and denied ever being at Jones’ house, claiming that he made the story up.
