An Emporia man has died after a large tree limb fell on him.

Officers were called to the scene in the 2000 block of Road M just before 9:30 a.m. Monday. The Lyon County Sheriff's Office says two men were hosing down a tree that had caught fire. Investigators believe a lightning strike started the blaze.

A large limb fell on top of the men while they were working. Kenneth Fuller, 86, received minor injuries and refused treatment. Gary Fuller, 49, was taken to a nearby hospital with critical injuries.

Gary died a short time later.

The Lyon County Sheriff's Office is investigating the case.
