An eastern Missouri man has died from injuries suffered when he picked up an explosive device in his yard earlier this month.
Authorities say 51-year-old Michael Keen of St. Charles was doing yard work on the afternoon of July 5 when he found a mortar shell. He picked it up and it blew off part of his hand and caused several other injuries, including internal injuries.
Keen died Monday at Barnes-Jewish Hospital.
Police don't know what the device was doing in Keen's yard. An investigation continues.
