Authorities found Mike's abandoned boat and truck at Lake Seminole, and it was initially suspected that he had probably had a fatal accident there.
But Cheryl Williams, Mike's mother, didn’t believe it. She was right not to.
Mike had been the victim of a planned murder between his wife Denise and his best friend Brian Winchester.
They had been having an affair since 1997, and just six months before Mike disappeared, he purchased a $1.75 million life insurance policy from his friend.
The pair seemed to have gotten away with it, until Brian was arrested for pointing a gun at Denise in 2016 as their marriage began to fall apart.
From there, Brian made a deal with prosecutors and agreed to immunity in Mike's death in exchange for revealing what happened that day.
His confession revealed that he pushed Mike from the boat and shot him after he was able to swim to a stump and attempted to hold on.
"He was panicking and I was panicking," Brian testified at the time. "None of this was going like I thought it was gonna go."
