You cannot try to murder your ex-wife and then avoid a judgment against you for compensatory or punitive damages by filing bankruptcy.
The Court of Appeals for the Seventh Circuit rejected the effort of David Larsen to use the bankruptcy system to avoid his financial obligation to his former wife. Larsen tried to kill Teri Jendusa-Nicolai and, although his effort was unsuccessful, she suffered a miscarriage and the amputation of all of her toes. The toes were amputated secondary to frostbite – the jerk beat her with a baseball bat and left her in a garbage can filed with snow, secreting the can in an unheated storage facility.
A civil suit was filed, resulting in a judgment of $3.4 million for her and $300,000 for her (then) husband and daughters for loss of consortium. Larsen then filed a Chapter 7 proceeding seeking to discharge the judgment debts.
