House Explosion Investigation

Authorities have wrapped up their on-site investigation into Thursday's house explosion on Whitemarsh Island. Around noon Thursday, a house on Mapmaker Lane went up in flames, killing at least one person.

Savannah Chatham Metropolitan Police, the ATF and Savannah firefighters spent Friday sifting through the rubble. They still don't know what caused the blast. They've sent their findings to the ATF Crime Lab, but they don't expect any results for several weeks. Investigators have tentatively identified the body, but won't release the name until they notify the family.
