Investigators are still trying to figure out what started a fire that destroyed a house in Holden Tuesday.One of the owners was home when the fire broke out.As Meghan Hayward tells us, he has some good samaritans to thank for his safety.”I’d gone to Lowe’s to pick up some stuff. Came over the Whiting Hill and saw the smoke near here.”Ronald Treat followed the smoke until he ended up on Balsam Drive in Holden.”When I drove in, I could see him standing on the roof and he had the dog with him and was waving his arms at me.”Treat called 911. Another person who had also noticed the smoke arrived at the home.”She ran up and he told her where to get a ladder and she got a ladder over there. By the time that happened, I drove up the rest of the way and went over and helped him get the dog down the rest of the way.”Treat says there was a lot of fire coming out of the basement.He was relieved when they got the homeowner and the dog on the ground.”He was pretty upset. I think he had a lot of smoke in his lungs. Really smokey inside the house, the whole house was full of smoke.”The homeowner, Shane Geiser, was taken to the hospital to be treated for smoke inhalation.Treat says he’s gotten a lot of phone calls from folks who have heard what he did but to him, it’s no big deal.”It’s encouragement to do things like that. I think a lot of people would do the same thing that I did.”The first floor of the home eventually caved in, forcing fire crews to back out.The Fire Marshal’s Office says it may be a few days before they can determine the cause.
