Attorneys handling the case of a 91-year-old Tucson man accused of critically injuring an El Tour de Tucson bicyclist have worked out a deal that guarantees the driver will receive either probation or less than two years in prison.

William Wilson pleaded guilty to attempted leaving the scene of an accident causing serious physical injury in Pima County Superior Court Wednesday and will be sentenced June 22.

If Wilson had been convicted of his original charge, he could have received up to 12.5 years in prison.

Sixty bicyclists were heading west on Ina Road last November when Wilson, who was heading east, tried to turn north onto Westward Look Drive and collided with 10 of them, according to Pima County Sheriff's Department officials.

Five cyclists were injured; their injuries ranged from stiffness and road rash to a life-threatening brain injury.

Wilson got out of his car to check the damage before getting back in and driving away, witnesses told authorities.

Some of the witnesses said people started yelling obscenities at Wilson after he got out of his car.

At the time of Wilson's indictment, David Berkman, chief criminal deputy county attorney, said that stopped traffic may have blocked Wilson's view of the oncoming bicycles.

Prosecutor Bruce Chalk said Gary Stuebe, the man critically injured in the incident, is still struggling to overcome his “serious life-changing head injuries.”

If Wilson is placed on probation and successfully completes it, his charge could be designated a misdemeanor.
