Cleveland man pleads guilty in fatal heroin dose

CLEVELAND (AP) — Authorities say a Cleveland man who sold a fatal dose of heroin last year to a 19-year-old man has pleaded guilty to involuntary manslaughter in his death.

Cuyahoga County Prosecutor Timothy McGinty said that 24-year-old Michael Karkoska was sentenced to four years in prison Monday after pleading guilty to charges that included involuntary manslaughter, corrupting another with drugs and trafficking.

Authorities say Lanny David Gullion III was found dead in October about a block from where the drug sale took place.

McGinty says prosecutors were prepared to present evidence that included videotapes and text messages tying Karkoska to the deadly transaction.

McGinty's office says Gullion was one of nearly 200 people who died of heroin overdoses in Cuyahoga County last year.
