CRYSTAL BEACH, Texas (AP) — A man who had been jogging during a thunderstorm may have been killed by a lightning strike.

Galveston County sheriff’s Maj. Ray Tuttoilmondo said a passerby spotted the body of Isaias Lara-Martinez lying facedown on Crystal Beach on Bolivar Peninsula Wednesday afternoon.

Tuttoilmondo said Lara-Martinez had burn marks on his chest and there was no indication of foul play.

Officials said Lara-Martinez had been out jogging during the thunderstorms that rolled through Galveston County.

An autopsy has been ordered.
