Investigators looking into the cause of a gas explosion that killed five people in Allentown last week are focusing on an “imperfection” in a pipe near the blast site.
An Associated Press report states that on Saturday, investigators told The Morning Call of Allentown they were zeroing in on an abnormality in a section of pipe.
Fire Chief Robert Scheirer said workers were to dig up the section of pipe Sunday and take a closer look. The Pennsylvania Public Utility Commission will then send the pipe to a forensics expert.
A spokesman for UGI Utilities Inc., says the PUC is running the inspection and will report to the National Transportation Safety Board.
