The cause of the propane tank explosion at Crocker Park earlier this month was deemed "undetermined," according to Bill Krugh, spokesperson for the Ohio State Fire Marshal.
Fire officials never said what sparked the initial fire that caused one of two propane tanks to explode, damaging three floors of the American Greetings building that is under construction.
A spokesperson for AmeriGas confirmed that the company had two 1,000 gallon propane tanks on the premises for temporary fuel during construction. The tanks were then leased by Walsh construction company.
Westlake Building Commissioner Don Grayem told newsnet5.com that the tanks were no longer being used and were scheduled to be removed from the site.
