Two men were found unconscious in the basement, and another man was found on a porch. Authorities say the three were in critical condition when taken to Nebraska Medical Center.

Two other people escaped from the house and were in serious condition when taken to Creighton University Medical Center.

Another man was treated by firefighters.
