CLARKSVILLE, Tenn. (AP) _ A former soldier was convicted Saturday of murdering four co-workers at a Taco Bell restaurant during a robbery in 1994.

Prosecutors are seeking the death penalty for Courtney Mathews. They said he forced the workers to lie on the floor after the restaurant closed and shot them execution-style.

The sentencing phase of the trial is set for Monday. Mathews, 21, also could be sentenced to life in prison or life without possibility of parole.

Mathews, who did not testify, briefly closed his eyes and looked down after hearing he was found guilty of four counts of murder and one count of aggravated robbery. The families of the victims cried.

Killed were Marsha Klopp, 24, Kevin Campbell, 22, Angela Renee Wyatt, 22, and Patricia Price, 39.

A helicopter repairman with the 101st Airborne Division at nearby Fort Campbell, Ky., Mathews had worked at the Taco Bell for 10 days as a part-time dishwasher and food handler.

A co-defendant, David Housler, is awaiting trial.
