FAIRBANKS - The Department of Public Safety continues to offer few details about what caused Sunday's explosion at a home on Chena Ridge - other than to say it did not involve a meth lab.
The home of 20-year-old Dane Koponen was been cordoned off and secured after Alaska State Troopers found numerous hazardous chemicals.
Authorities have declined to name the chemicals, but say the public is not at risk.
Koponen suffered burns and has been listed in satisfactory condition at Seattle's Harborview Medical Center since Monday. He's the grandson of former state Rep. Niilo Koponen.
