A weekend explosion and fire left as many as 100 people homeless in Des Moines. The blast and blaze destroyed an entire apartment building at Willow Park Apartments on Saturday afternoon, gutting some 30 units.

Des Moines police suspect the explosion was sparked by two men who were cooking methamphetamine. They were the only people injured in the fire. They’re identified as 21-year-old Jerraun Smith and 28-year-old Rodney Mellows. Both are being treated in Iowa City for severe burns.

No condition reports are being released. As yet, no charges are filed.
