Explosion experts joining Mission Ridge Rd. investigation Monday

Posted: Updated:

ROSSVILLE, WALKER COUNTY (WRCB)-- Fire investigators are still trying to figure out what caused a home on Mission Ridge Road to explode Wednesday night.

Saturday afternoon, Channel 3 learned new sets of eyes will examine the case.

Walker County Fire Chief Randy Camp says two explosion experts will be in town early Monday to try and determine a cause.

Friday, State Fire Marshal officials used "sniffer-dogs" to comb the remains, but nothing was detected.

Investigators say the 60-year-old septic tank might be to blame, after a methane detector found chemical levels to be three times higher than usual.

Thankfully, the tenants were not home when the explosion occurred.
