(upbeat music) - This was all horse pasture over here. And this was all our yard. At one time, we owned 120 acres here. It was our dream home. Todd designed every inch of that house himself. - Did you love Todd? Oh, I don't even think I ever didn't love Todd. I think I fell in love with him so quickly. And I know that he loved me. - Firefighters found him unresponsive outside the home on County Road 215. He died of smoke inhalation and thermal injuries. - Linda had it occurred to you that you would be a suspect in your husband's death. - It didn't even occur to me that it could even be ruled arson. All I'm thinking was, how did this happen? (dramatic music) - We are right now in our driveway, facing where our front door used to be. - So what was it like on that January 7th? - It was in the low 30s. - It rained and drizzled all day. - He's watching hunting shows upstairs. He's not doing much of anything. I'm doing laundry. I heard a scream like no other scream that ever heard from him. And I just rushed upstairs to see what in the world happened. And as soon as I got around the corner, I could see a fire across the living room. He looked like he was fighting the fire. I just rushed out of the house. - But the house is on fire? You didn't think about calling 911? - That wasn't my first stop. My first stop was to get out Todd's gonna get out. As long as he knows I'm out, he's gonna get out. I thought I've gotta get help. I got in the van and I started to back up and then all of a sudden he's there and he's jumping around and he's patting himself. His skin is burnt terribly. - And I lost sight of him. I don't know where he went to. - Did you know you had run over your husband? - No. (dramatic music) - What do you believe happened?
