MADISON, Wis. (AP) — A Wisconsin man who was convicted of killing and dismembering his parents was sentenced to life without parole. A judge saying his obligation to protect the public required the stiffest possible sentence for Chandler Halderson. The 24-year-old was convicted in January of first-degree intentional homicide, mutilating a corpse and hiding a corpse in the July deaths of Bart and Krista Halderson. Investigators said Halderson killed his parents after his father discovered he had been lying about attending a technical college. Prosecutors said it was one in a web of lies he told about work, school and being on a police scuba dive team.
