INDIANAPOLIS -- The feds are no longer investigating a deadly explosion in Indianapolis.
The National Transportation Safety Board stepped aside Tuesday. They were originally brought in to look into underground gas pipes, but they found no problems.
Two people died in Saturday’s explosion, including an elementary school teacher.
Officials still don't know what caused the blast.
