An employer may be held liable for vehicular manslaughter committed by an employee after hours. An employee became intoxicated at a company party and then later, after he had returned home and then left again, crashed into another car, killing the driver. The parents of the victim may sue the employer because the employee was acting within the scope of his employment when he got drunk.
