Karl Karlsen arraigned on murder and insurance fraud charges in sonâ??s death

Karl Karlsen

A 52-year-old upstate New York man accused of killing his son in a staged accident to collect his life insurance is due back in court.

Rochester media report that Karl Karlsen will be arraigned Monday on charges of second-degree murder and insurance fraud in Seneca County Court.

Karlsen's 23-year-old son Levi Karlsen was found crushed under a truck he'd been working on at the family's Finger Lakes property in 2008.

Karl Karlsen told sheriff's deputies he'd come home and found his son dead. But investigators learned this year about a life insurance policy taken out days before the death and arrested the father.

After the charges in New York, police in California reopened an investigation into a 1991 fire that killed Karlsen's wife.

Karlsen has said he is innocent.
