A man accused of trying to shoot another man to death in downtown Sudbury two years ago has pleaded not guilty to all of the charges against him.

During a court hearing in a Sudbury court Thursday, Alex Klem enter a plea of not guilty.

The hearing currently underway is expected to determine if Klem is mentally fit to stand trial.

Alex Klem is accused of shooting Sudbury business owner Tony Monteleone in October 2010.

The shooting happened in the middle of the day and was followed by a dramatic arrest in New Sudbury a few hours later.

The hearing is expected to last two days.
