Colin Ratiu admitted in court on Tuesday that he was drunk behind the wheel when he ran over 24-year-old Andrew Prior last year. The 24-year-old Northeastern graduate was riding his scooter near Roxbury Crossing when he was hit last November.

Witnesses said Prior was thrown 150 feet.

WBZ-TV’s Alana Gomez reports.

While police investigated the accident, Ratiu went on with his life, according to prosecutors.

“During that time period of three months, Mr. Ratiu got married, went on a honeymoon. He continued celebrating his life all the while during the time when the Prior family was hurting, and really wanted to know what happened,” said the prosecutor.

But, an anonymous tip led police to Ratiu.

They found Ratiu’s SUV parked at his mother’s house with pieces of Prior’s scooter still embedded in the front end.

“Mr. Ratui’s family did the unconscionable thing of putting us through hell, looking for the coward that killed my son. This family had to have been aware of what he did,” said Prior’s father in court.
