Lawrence Trujillo said he can't remember much of the night that changed his life, and the life of Frank Bingham, forever.

"There is so much to say but there (aren't) words in the dictionary to explain what I've done," Trujillo told 9News from the Denver jail. "The 'sorry' isn't enough. It's the correct thing to say but it's too easy. There needs to be more and I haven't found those words yet."

Last week, Trujillo pleaded guilty to all 13 charges he faced in the devastating Nov. 10 hit-and-run that destroyed a family and shocked a city.

Bingham was out for hot chocolate with his wife and two young children when a drunken Trujillo ran a red light and mowed the family down, injuring Bingham and killing his wife, Becca, 39, and their two children, Macie, 4, and Garrison, 2.

In the interview aired Sunday, Trujillo talked for the first time about living with the accident and why he never hit the brakes after hitting the family.

Trujillo said that he didn't realize he ran a red light, and while he knew he ran into something, he didn't know what.

"You think a parked car, newspaper stand, a light pole or something. You don't think a family," he said.

It wasn't until he was in an interview room at the police station, Trujillo said, that he realized it was a family he hit.

"I heard detectives talking and this is when I really put it together," he said. "I remember them talking . . . 'Yeah, that is him with the mother and two children, the fatal accident.' And I was sitting there thinking, 'I really hope there is a guy next to me.' "

Trujillo said he doesn't blame those who think he is a monster.

"What people don't realize is I think about that family every day, every night," he said. "I actually have a picture of that family in my room. So it's tough being a dad and then manning up to what I did to a family. It's tough. It's the worst thing you can imagine doing to a family, and I did it."
