A man has been sentenced to life in prison for killing his father with a crossbow and hiding the corpse in a freezer inside a northeast Missouri home.

The Hannibal Courier-Post reports that 32-year-old Carl Goldberg, formerly of Las Vegas, was sentenced Thursday. He pleaded guilty to second-degree murder in February.

The body of Carl Maxwell was found in October 2015 inside a freezer in a Hannibal home, but authorities believe he was killed in February 2015.

In a written confession, Goldberg said he and Maxwell were involved in an argument, after which Maxwell fell asleep in a chair. Goldberg said he used the crossbow to shoot Maxwell in the chest as the older man slept. After about 20 minutes, he shot Maxwell a second time in the head.
