HETH, AR - St. Francis County authorities say the source of an explosion in Heth that killed a man this week appears to be an acetylene tank that was stored in a shed.
The bomb squad of the Arkansas State Police is investigating the blast, which killed 40-year-old James Boles.
The blast broke windows a quarter-mile away. Investigators say the valve was open on the tank.
The explosion destroyed the shed and a couple of nearby travel trailers, in addition to the damage to nearby homes.
