Dec. 27, 2000-- A family in Orem is dealing with a double tragedy.

Last night a father and his six-year-old son were killed as they tried to cross one of the city's busiest streets. News Specialist John Daley has details.

An investigation into the cause of this accident is continuing. But for now, police say it appears the father and the son never saw the truck coming, and the driver of the truck never saw them.

On the day after Christmas, a tragic combination of circumstances for thirty-one-year-old Lloyd Marble and his six-year-old son Casey.

They were crossing State Street in Orem together on a bike about 8:00 p.m. under dark skies. The busy state road they were on is dimly lit, and to make matters worse, police say the overhead light there is out and there is no crosswalk.

A tow truck barreled into them. The driver apparently didn't hit the brakes until after Marble and his son had been hit.

Lt. Ned Jackson/Orem Police Dept.: "THE TOW TRUCK DRIVER WAS UNDER THE SPEED LIMIT OR CLOSE TO THE SPEED LIMIT BUT NOT OVER. JUST DOESN'T LOOK LIKE HE EVER HAD THE CHANCE. BY THE TIME HE COULD SEE HIM, THERE JUST WASN'T TIME TO STOP AND AVOID THE ACCIDENT."

Police say Marble's wife and their other children, traveling home after shopping, came upon the accident just after it happened.

Lt. Ned Jackson/Orem Police Dept.: "REALLY TRAGIC TO HAPPEN THE DAY AFTER CHRISTMAS. UH, IT'S GONNA BE SOMETHING. YOU KNOW, CHRISTMAS IS A HAPPY TIME AND YET TO ASSOCIATE THIS WITH A DEATH OF A HUSBAND AND SON, OR A FATHER AND BROTHER, IT'S GOING TO BE DIFFICULT."

A neighbor tells Eyewitness News Lloyd Marble had a reputation as being very safety conscious with reflectors.

Jessica Darrington/Neighbor: "IT WAS A SHOCK. A COMPLETE SHOCK. I MEAN, THE DAY AFTER CHRISTMAS. ESPECIALLY SO MUCH A SHOCK BECAUSE LLOYD HAS ALWAYS BEEN A SAFETY FANATIC."

Lloyd Marble is survived by a wife and three daughters age 8, 4 and 2. A trust fund is being set up to help with funeral arrangement in the names of Lloyd and Casey Marble, through Key Bank.

Meantime, police are still trying to figure out exactly what happened. Anyone with any information is asked to call Orem police.
