BOULDER -- Investigators say 43-year-old Sean Marino was driving up to 90 miles an hour in a 30-mile-an-hour zone Monday night when he caused a chain-reaction crash that sent ten people to the hospital.
Automobile wreckage was scattered for blocks.
Police say Marino's pickup truck slammed into the rear of one car with two adults and an infant inside, and then he smashed into a string of other vehicles with children inside.
"I'm shocked that we don't have someone seriously injured or dead out of this because, as you can see, it's a pretty horrific scene," says Boulder Police Commander Carey Weinheimer.
Of the ten people who went to the hospital, a little girl who needed 12 stitches to her head was hurt the most seriously.
"I've lived here for about 20 years and there have been a couple of other big accidents, but none that compare with this," says Pollyanna Demitro.
Marino first told police he didn't know what had happened.
"He also said at one point that the accelerator was stuck," says Boulder Police spokeswoman Kim Kobel. "Then later when he talked to another officer he said that the brake wasn't working."
Officers on the scene said Marino's speech was slurred. Court records show he has a long arrest record for domestic violence and assault, also told investigators he didn't know he was hitting other cars.
"He told a number of different stories as he was talking to us, at first denying remembering anything or denying being on any drugs or medication," Kobel says. "But then later he admitted that he had taken Percocet.''
Marino sustained broken bones and cuts in the crashes.
He was being held on a felony charge of vehicular assault along with reckless driving, DUI, and hit-and-run. Bond is $50,000.
Marino is scheduled to make a court appearance Thursday.
