MONROE — On top of the sentence of a decade in prison and another 10 years on probation for reckless homicide in Rock County, defendant Mark D. McCoy, 51, will serve an additional 5 years behind bars, following his conviction on multiple felonies for weapons and drugs in Green County.
As part of a plea agreement, the defendant was found guilty Thursday by Circuit Judge Jane Bucher of possession of a firearm by a felon, possession with intent to deliver cocaine; and possession with intent to deliver methamphetamine.
The remaining counts against him — mostly additional drug felonies — were dismissed but “read in” to the court record.
He was one of three charged following an investigation by the State Line Area Narcotics (SLANT) team into a potential marijuana grow operation in the 500 block of 21st Street on the southwest side of Monroe.
He lived in a two-story, brick home that was raided on Feb. 10, 2022. Authorities claim in a statement that they have discovered a separate psilocybin mushroom grow operation in addition to the marijuana grow and 17,000 grams of marijuana, 50 grams of probable cocaine, and almost 3 grams of heroin. The garage at that location also housed a separate grow facility.
He was accused on the Green County charges of running a drug trafficking operation, producing THC and psilocybin, and possessing cocaine with intent to deliver, among other offenses.
McCoy caused a crash in 2023 killing a 55-year-old woman.
He was convicted for “two different theories of homicide,” according to court officials there. He was driving his 2020 Dodge Durango north on South County Road D near West Hanover Road in Janesville when he crossed the center line and collided with Susan Hohmann’s vehicle. She was pronounced dead at the scene.
During McCoy’s trial, it was discovered that he had alcohol in his system in the very early morning of the day of the homicide. Witnesses, however, did tell the jury that McCoy had sleeping issues and mentioned he had prior accidents while driving tired without alcohol.
He was found guilty of negligent homicide by operation of a motor vehicle and second-degree reckless homicide. Rock County Judge Ashley Morse sentenced McCoy to 20 years of prison — the first 10 years in prison and the remaining 10 under extended supervision.
He is currently incarcerated at the Dodge Correctional Institution, a maximum-security prison in Waupun, according to state Dept. of Corrections records. He is set for release there in 2043.
