A capital murder trial scheduled to start Monday has been delayed while the Utah Supreme Court considers a pending petition for an appeal regarding the chain of custody of DNA evidence.

The trial had been scheduled to run through April 18, and 1st District Judge Ben Hadfield had issued a decorum order outlining his rules for proper courtroom conduct.

Glenn Howard Griffin, 50, is facing a capital murder charge in connection with the 1984 slaying of Bradley Newell Perry, 21, who was killed while working the night shift at a family owned convenience store/gas station in Box Elder County. If convicted, Griffin potentially faces the death penalty.

A co-defendant in the case, Wade Garrett Maughan, is also charged in the case.
