SARASOTA, Fla. -- A man accused of giving a victim a sort of opioid some 10,000 times more potent than morphine will spend at least a decade in prison.

John Michels, 39, was sentenced Tuesday to 11 years in prison and three years probation for manslaughter and sale/delivery of carfentanil in the March 2017 death of an Englewood man, according to a Sarasota County Sheriff's Office news release.

Gas station surveillance video is credited for helping to find Michels, leading to his conviction.

WWSB-TV reports from law enforcement Michels sold the victim the drug, promising to ease his pain. The two men did the drugs together, and it wasn't long before the victim began to overdose. Michels dragged him out of his car, leaving him at the side of the road in the area of Egerton Circle and Wexford Lane.

The video showed Michels with the victim a few hours before his death.

Deputies say Michels later admitted to providing the victim with carfentanil.
