Tears flowed in the courtroom on Wednesday for the 16-year-old teenager from Vacaville who died in a watercraft collision in July, for the young man blamed for the deadly crash, and for the families left to pick up the pieces.

"I am deeply sorry for what's I've done," said Tyson Dagley, a 20-year-old Australian man who was visiting Hawaii last month.

During his sentencing, Dagley again expressed remorse for what happened at Keehi Lagoon one month ago to the day.

Video was released by Dagley's attorney that showed exactly what happened.  Prosecutor say Dagley was looking to the side posing for his girlfriend when his WaveRunner slammed into Kristen Fonseca.  The California teenager died a day later.

"I go in her bed and smell her pillows and pretend it's her," said Fonseca's mother Evangelina Canton.

In court, Canton's hands trembled as she expressed her grief, pulling out a short poem Kristen wrote as a young girl.

"I dream I had a cell phone.  I scream when I'm afraid.  I'm an 8-year-old girl.  I want a motor scooter.  I wonder if I will ever have kids," said Canton.

Dagley was charged with third-degree negligent homicide.  He spent 12 days in prison before being freed on $100,000 bail.  Dagley pleaded no contest to the charge.

Judge Richard Perkins accepted the plea on Wednesday, gave him credit for time served, and agreed to clear Dagley's record if he stays out of trouble for a year.

It's a sentence Kristen's family compared to a traffic ticket.
