Final submissions were made on Thursday in the trial of an educational assistant accused of breaking the leg of a student with autism.

The Crown asked the judge in a Midland court to reject Corey Stibbard's explanations of what happened in December 2014, saying repeatedly that "Mr. Stibbard is not credible. He is Dishonest."

Stibbard previously told the court that Riley Dooley became violent and aggressive while at a Dollar Tree. He said that Dooley attacked him three times and was trying to defend himself.

That’s when he says he blocked a kick with his foot, causing Dooley to fall forward and break his tibia and fibula.  Stibbard originally told a store manager and Simcoe County District School Board authorities that Dooley had tripped and fell.

Meanwhile, the defence argued that a quote heard in a recorded conversation was a reference to aggressive behaviour before the alleged incident.

"He (Riley) was being silly."

Dooley’s mother says it's been difficult listening to the details about her son’s injury.

The judge decided to take some time to review all of the evidence presented during the trial, and will render a verdict in October.
