BETHESDA, Md. (AP) — A Maryland millionaire will soon be out on bond as he fights charges of "depraved heart" murder in a bizarre chain of events that led to a 21-year-old man's death.

News outlets report that a judge set day trader Daniel Beckwitt's bail at $100,000 in the death of Askia Khafra.

Beckwitt had hired Khafra to dig tunnels beneath his Bethesda home. The tunnels were supposed to part of a bunker.

In September, officers responding to a fire at Beckwitt's residence found Khafra dead in the tunnels. His death's cause was listed as smoke inhalation and thermal injuries.

The 27-year-old defendant is expected to soon be out on bond. His lawyers have describe Khafra's death as a tragic accident.

Prosecutors say Beckwitt was worried about a nuclear war with North Korea.
