Witnesses said that shortly after flipping his SUV, a teen driver climbed out of the car and, apparently in a daze, took off running. A 17-year-old was found by police officers near 2700 South and 1700 East. Police said they found alcohol in the Jeep.

"He was definitely drunk," said a man who lived in the neighborhood. He identified himself as "Dario."

"He was just laying (there). The cop had his knee in his back for a while. Then the ambulance came," Dario said.

At the scene of the crash, people were trying to help the Williams family. Lee said he saw a woman — who said she was a nurse — check pulses. He looked inside the smashed-up Jetta and saw a child on the floor.

"He was laying face down on the floorboards and just moving a little bit and I thought, 'At least he's moving,"' he recalled.

Lee expressed frustration with how long it took the police and paramedics to arrive at the crash. Minutes felt like hours before a fire engine finally arrived on scene.

"It was an excruciating wait," he said.

Fasting and praying

Police said they booked the 17-year-old into juvenile detention for investigation of driving under the influence. On Saturday, detectives were said to be conducting further investigations into the triple-fatal crash.

"It's just a major tragedy," Tuttle said. "It's a family that's torn apart."

On Saturday night, at least 200 members of Williams' ward gathered at the chapel to pray — just a few hundred yards from the scene of the crash.

Late Saturday while in the hospital, Williams told Michael Hennessy, "'I feel peace.'" Hennessy told those gathered to pray that Bishop Williams was up and walking around about an hour before the chapel meeting. Hennessy added that Sam Williams' vital signs looked good Saturday but that the next two to three days will be critical for the boy's recovery because of swelling in his brain.

A fund is being set up to help the Williams family at Zions Bank, President Wood said.

The crash is eerily reminiscent of two other recent deadly DUI accidents.

In November 2006, a man was allegedly driving drunk in a white pickup going the wrong way on I-80 near Knolls, Tooele County, when he struck a Pontiac Bonneville carrying four people. Three people in the Pontiac were killed, including the driver, Vakataha Mila, 43, of West Valley City and back-seat passengers Sosaio Fehoko, 69, and Valentine Kioa, 50, both of Salt Lake City. Jeffrey M. Harrison, 25, has been charged with three counts of automobile homicide.
