DETROIT -- Former Michigan State Police trooper Mark Bessner was sentenced to 5-to-15 years in prison Monday after being found guilty of involuntary manslaughter in the death of 15-year-old Damon Grimes.

This comes after a mistrial was declared in Bessner's first trial.

Bessner was in patrol car with his partner driving when they saw Grimes riding an A-T-V in his Detroit neighborhood in August, 2017.

It turned into a pursuit when the troopers tried to stop him for what was said to be a traffic violation. Bessner claimed Grimes reached for his waistband two times leading him to think there was a weapon.

The trooper tased Grimes who then crashed into a parked pickup truck and died from blunt force trauma to his head.

Dezanique Grimes -- Damon's older sister -- commented.

"We can't move on. Everyday we wake up and it's like he's not there. We walk past his room -- he's not in there."
