Wednesday's deadly house fire near the intersection of Dakota Avenue and South Niagara Street was preceded by "three big flashes" and "coinciding with all of them, there was a very loud pop."

That's what a neighbor told a Denver TV station.

An elderly couple, described as "two lovebirds," died in the blaze.

The man's scorched face was covered in 1-inch lesions and "I’m thinking it must’ve been something combustible to blow up right in his face,” the neighbor, quoted by Fox 31, said.

"I hope they are doing a very thorough arson exam,” the neighbor said.
