Officials still do not know what caused a Dec. 14 fire in Glendale.

The blaze burned so hot that it leveled an apartment building that was under construction and melted vehicles parked across the street.

A team of investigators spent five days on the scene and interviewed numerous witnesses, but officials have not been able to determine what started the blaze, according to a news release issued Monday.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), the Denver Fire Department, the Glendale Police Department, and the Colorado Bureau of Investigation participated.

"If information is developed in the future to indicate or warrant further investigation, the finding of undetermined can be changed," the release said.
