In February of last year 37-year-old Tyler Meier made a simple decision to head to a local Neillsville tavern to play pool. The subsequent decision to punch a man who later died from his injuries, will haunt Meier for the rest of his life.

On Monday Meier is being sentenced in Clark County Court, and could face years in prison.He pleaded no contest to felony murder charges last December.

On Sunday, we talked to Meier in his mother's home in Neillsville, surrounded by his wife Nicole, and their three children.

Tyler Meier's life story is spotted with trouble involving alcohol and drugs. But in the last six years he says he's cleaned up his act. In 2004 he began working with the Neillsville Police Department as a confidential informant reporting on drug activities.

His motivation was noble, to stop drugs from destroying others lives, but many of the people in Neillsville felt differently about Tyler's activities.

He describes how he’s lived the past few years, “First of all your scared, I’ve been looking behind my back for years, not visiting my mother, staying away from my own family.”

It was his involvement with the police department that sparked an argument at the Brickyard Bar & Grill, on that fateful night more than a year ago.

Tyler describes what was going through his mind during an argument at the bar, “Call it presumption, call it fear, call it panic at the totality of the circumstances.”

Feeling closed in and afraid of getting hit, Tyler punched Keith Young, who fell to the ground and later died of his injuries, “For a tragedy to come out like that, that I can't take back, that punch, I can't take back none of that,” Tyler says.

Tyler says the last year has been painful, every day reminded of the man who died by his hand. But he says he's not a murderer, and he wants to make amends for his actions, by teaching others about the dangers of drugs. Monday he's hoping that wish will be granted.

Tyler says, “First off I want the lords presence in that courtroom. I'm a good guy and I know that I can go the schools and make a difference. I've learned one thing out of this whole thing, humility.”

Meier says as a family man he cannot begin to apologize to Keith Young's widow and child, he says he wants to pay reparations to her, for his actions last year.

Monday Meier will be sentenced in Clark County Court.
