Teen Clerk Abducted, Killed

A woman whose abduction was

Some 800 miles away, in Wilcox, Ariz., police arrested 24-year-old Johnny Williams, a former Marine, reports CBS News Correspondent Jennifer Miller.

Police said he turned up at an Arizona hospital with a gunshot wound, and authorities realized the woman's truck was parked outside.

The body of Megan Leann Holden, a 19-year-old college student from Chandler, was found on the side of Interstate 20 on Friday near Stanton, about 380 miles west of Tyler, police said.

"It is apparent that she has died of a gunshot wound," Police Chief Gary Swindle said, declining to give details.

A surveillance videotape from late Wednesday "shows Megan getting into her truck and the (man) running up behind her and either hitting her or pushing her," police spokesman Don Martin said.

Police say Holden never knew her abductor or even that he was coming after her.

Two days later, her body was found near Stanton, about 380 miles west of Tyler.

Tyler Police Chief Gary Swindle provided little detail about the killing, but said Holden died of a gunshot wound and added that "we have every indication that she was shot at the location where her body was found."

Authorities said the suspect kept heading west as he continued his crime spree, attempting a robbery at an Arizona RV park. It was during the robbery attempt that a store worker fired the shot that landed Williams in the hospital, authorities said. His condition was not immediately known.

"He said, 'This is robbery, I want all the money in the cash register,"' store worker Richie Chapman said. "And as he said that, he drew a weapon from underneath his shirt, and I drew and fired."

It was not known if Williams had an attorney.

Police said Williams, who was honorably discharged last year after four years as a Marine, was arrested last month in Tyler on a cocaine possession charge. He was released the same day on $2,000 bond.

Police said Williams also was involved in an armed robbery at a convenience store in Texas on Thursday.

Texas prosecutors said they would seek kidnapping and murder charges, and other counts may follow.

The kidnapping and killing has shocked this town of 86,000 people.

Martin, the police spokesman, said the victim's mother was in a wreck while driving to Tyler. She was shaken and covered with cuts and bruises after flipping her car three times, a relative said.

A makeshift memorial was set up at the Wal-Mart on Friday. More than a dozen flower bouquets, some with notes including "Megan we will miss you," were placed on a bench by passing shoppers.

"While I was here, I just wanted to do that," said a tearful Jill Kitchens, who placed flowers, a red teddy bear and a red candle as she left with a cart of groceries.

Some shoppers said they were still shaken.

"We're such a small town here; it's just a total shock," said Mary Osborn, 24, as she loaded groceries. She said she kept her pepper spray clutched in her hand in the parking lot.

"You always have to be aware of your surroundings," she said.
