In 2008, Beal's wife died after she fell down the stairs and a heavy piece of furniture landed on her. A coroner called the case "mysterious" and named several factors in her death, including high levels of lead in her body.

Beal dated and was business partners with 48-year-old Ildiko Karjnyak, who died Tuesday after a device in a package exploded in her day spa.
