Channel 11 News is learning more about a fatal house fire that erupted in Mercer County on Monday.

An 88-year-old man whose name hasn’t been released died in the three-alarm blaze along Route 19.

Firefighters told WPXI they had trouble getting into the house because the man who lived there was a hoarder.

Inside the house, there was only a small walking path, which made it difficult to battle the blaze, firefighters said.

The victim was found dead in the basement of the home.

The cause of the fire is under investigation.
