A Utah teenager convicted earlier this week of murdering a convenience store clerk wanted to slay more people in a killing spree that would have extended from Salt Lake City to California, an informant testified Wednesday.

The testimony of Jeffrey Chidester, 18, a lifelong friend of Edward Bennett's, came on the first day of Bennett's penalty hearing in District Court.At the conclusion of the hearing, a jury will be asked to determine if the 19-year-old Lehi man will be imprisoned for life or executed by lethal injection for the Feb. 9 slaying of Michelle Moore.

Moore, 21, was a newlywed who had been on the job at the Stop `N Go store for two weeks when Bennett put a .45-caliber bullet through her forehead. She had moved to Las Vegas from Grand Junction, Colo., two months before.

During Bennett's trial, Chidester testified Bennett confessed to the killing March 5 during a conversation at a park in Pleasant Grove. On Wednesday, Chidester said Bennett and Joseph Beeson, 18, of Orem, wanted to embark on a killing spree.

"He said they were going to take a gun to a shopping mall and start shooting - just open fire on whoever they see," Chidester testified. "They were going to go on a killing spree from Salt Lake City to California.

"They were going to blow people away until they got shot. He (Bennett) said he wanted to leave one bullet, at least, for himself."
