"(They) almost killed my son and his father, could have," said Victim's mother Annika Dean. "They are so lucky."

It was unbelievable -- a hit-and-run driver knocked a father and son from their motorcycle.

"And this car ran a red light and he smashed into the front of the motorcycle," said 8-year-old Alex Doyle. "And then the next thing I knew we were on the ground just laying there."

Their helmets saved their lives, though Alex's father was knocked senseless and can't remember anything.

We reported the exclusive story from the Lakewood intersection last week. This case went unsolved for days, but after our story aired, the suspect's girlfriend became alarmed. She tried to get him to give himself up. When he didn't, she turned him in.

"We're attributing that to the media attention," said Lt. Bret Farrar of Lakewood Police. "We got a phone call from somebody who was actually in the car who tried to convince the driver to turn himself in, but that wasn't quite working itself out."

When police arrested 19-year-old Jacob Hyneman of Kent, it came out that during a fight with his girlfriend as she pointed to the motorcycle, he intentionally hit it.

"They were fighting and she said: 'Wouldn't that be funny if that was my ex-boyfriend?' " Annika Dean said. "That made him mad and he ran right through the red light and purposefully hit them and took off."

Lt. Farrar says, "He may have an anger management problem and that's probably one of the things the court will discuss."

Hyneman is in jail charged with vehicular assault and failure to stay at the scene of an injury accident.

"It's horrible," Annika Dean said. "It's disgusting to me that somebody would purposefully hit a motorcycle because they were mad. It's disturbing."

She shudders to think what could have happened to Alex and Pat just because police say a jealous boyfriend took his anger out on innocent victims.
