A Windsor man has pleaded guilty to two out of the four charges he faced in his impaired driving trial on Friday.

Calvin Crosby, 25, pleaded guilty to dangerous driving causing bodily harm and dangerous driving causing death.

On Thursday, Justice Stephen Rogin ruled blood and breath samples would not be excluded.

Crosby was the driver of an SUV in April 2014 that collided with a sedan on Lauzon Road, claiming the life of 20-year-old Katie Robson.

"It's been a long time coming, but they finally got to a point where the evidence was going to stand against Mr. Crosby, and the defence decided to try to plea it out," said Katie's father Paul Robson, after the trial concluded.

"We just want to get it over with.and move on. It's all we can do" added Robson.

John Sitter, Crosby's defence lawyer, told CTV Windsor, "I know he feels terrible about Miss Robson, absolutely terrible. They were friends, it's a horribly tragic situation, an insoluble situation that there's really no solution."

Sitter said he wanted his client to go to trial, but Crosby felt responsible and let his conscience guide his decision to plea.

"Mr. Crosby is comfortable with his decision, he's ok, there's still the unfortunate tragedy that took place, and there's nothing we can do about that right now to make anyone right," said Sitter.

Crosby remains out on bail until sentencing. A hearing to determine the date will be held on May 12.

Meantime, a separate trail about the same crash was taking place down the hall in superior court on Friday.

Kyle Colthurst, 28, was the driver of the other vehicle in the crash that ultimately killed Katie Robson. He's pleaded not guilty to five charges, including dangerous driving causing death and failure to stop at the scene of a crash.

An accident reconstructionist, who disputes the police report, was cross-examined by the prosecution on Friday.

His trial is now adjourned until May 1 when final submissions will be heard.
