DES MOINES, Iowa -- A Clive man was sentenced Wednesday after being found guilty of second degree murder earlier this summer.

Stephen Jonas, 50, was sentenced to 50 years in prison for the death of Zachary Paulsen, 21.  Jonas must also pay $150,000 in restitution to the victim's family.

Jonas sat in silence Wednesday morning as Paulsen's family spoke on the impact his actions have caused their lives.

"You have broken our hearts.  You have no understanding of who the person Zachary was; he was generous, thoughtful, kind, smart and loving," says Paulsen's Mother Patrice Paulsen.

Patrice spoke about her only child and his bright future as a diesel mechanic being cut short.

"We watched Zach grow to be one of the kindest and most giving persons we could imagine.  My wish for you Mr. Jonas is you will find the strength to be a man and admit your horrible sins, it will be your only salvation."

Jonas was convicted in July of second degree murder.

Authorities say on August 23, 2014 Paulsen was found dead along the Clive Greenbelt Trail, he'd be stabbed 35 times.

Jonas claimed he killed Paulsen in self-defense.

During the trial the prosecution argued Paulsen rejected attempts at a one-night stand and kicked Jonas off his family's property.

Jonas confronted Paulsen again a week later.

"We had a son and then you a sick predator,  who couldn't have your way with him, had to end his life. Not once have you shown any remorse for what you have done to our son," says Zachary Paulsen's Father Kurt Paulsen.

Kurt said his life has been forever changed because of Jonas' actions that day.

"May your days in prison be long and horrible, may you suffer for stabbing our son and leaving him to die, damn you for coming into our lives. May God have the ultimate vengeance on you."

Jonas will be required to serve 35 years of his 50 year sentence before being eligible for parole.
