Mo. Missouri man dies in accidental explosion

BOONVILLE, Mo. (AP) — A central Missouri man has died of injuries he suffered in the unplanned detonation of a homemade explosive device earlier this month.

The Cooper County sheriff told the Columbia Daily Tribune  that 60-year-old Earl Fredrich died Monday night at University Hospital, where he had been taken after the blast on June 7.

 Sheriff Jerry Wolfe says Fredrich was the longtime owner of Fredrich Electronics in Boonville. He lived in rural Cooper County and had a hobby of building remotely triggered explosive devices.

Wolfe said investigators have concluded the blast was accidental and occurred when a device with which Fredrich was experimenting accidentally detonated earlier than planned. The sheriff says no one else was hurt.
