Omaha fire officials have identified the man who's body was found in a burning home at 20th and Vinton Sunday morning.
The death of 55-year-old Dennis Hansen was caused by smoke inhalation, according to preliminary autopsy results.
According to fire investigators, Hansen had a long history of depression.
The cause of the fire was determined to be a mattress in the bedroom that was intentionally ignited.
Investigators found no evidence that anyone outside of the home set the fire and all possible accidental causes were also ruled out.
Fire crews were called to the area of 20th and Vinton around 6:30 Sunday morning after someone saw smoke coming from the home.
After firefighters put the fire out, they found Hansen's body inside.
Most neighbors were not aware of the fire or that Hansen was found dead inside.
“I'm sorry that I did not realize the sirens and everything, there was a neighbor in trouble,” said Laura Harrington-Criger. “I'm sorry because this is the kind of neighborhood where if you see someone having trouble no one hesitates and wants to help and I'm sorry we weren't there. He was a wonderful man. Didn't know his name, but he was very friendly and very helpful to our family."
Harrington-Criger said she she won't soon forget Hansen. “I wish there was something that I could say to the family. All I can say is that I'm so sorry and if there is anything this neighborhood can do, we offer condolences, we offer prayers.”
Channel 6 News spoke with his family. They said he leaves behind two children.
