I originally posted this message on the Unsolved Mysteries message board, as I could have sworn this was a UM piece, but there's a likelihood that it wasn't on UM and perhaps on another crime show. I know I've seen it somewhere, so if anyone has any details at all, your help is appreciated. thanks.

There was this case where a man, likley a police officer, who was a suspect in a fire of a home that killed his girlfriend. He may have called the fire in himself. Fire took place around 6 or 7 a.m. A convenience store security camera got a picture of him driving by the store at a certain time, and it was later conclued that he would have only had four minutes bewteen the time of driving by the store and setting the house on fire. There was speculation as to whether or not that was enough time. If I'm thinking of the right case, there was some discrepancies in his log for that evening

The only case I can think of that comes close is John Maloney. He is a former Wisconsin detective who was convicted of the 1998 murder of his wife Sandy. The case was presented in a Forensic Files episode called "Burning Desire". It was also featured on the CBS series 48 Hours.

I don't know if this is the case you're actually thinking of, but it's worth a shot to find out.

Wow, the threads in this folder are older than dirt!

I don't know the names of those involved, but I'm pretty sure it's not case of Maloney in Wisconsin. I think they were getting a divorce and he's the guy who set his wife on fire on the couch, trying to make it look like she fell asleep while drinking and smoking and caught herself on fire. But the authorities found that one out pretty quick.

This other case... The cop had a girlfriend and he stopped by her house very early in the morning. One theory was that he had murdered her the night before, then came by in the morning to set the body on fire to cover up the murder. When he stopped at her house early in the morning, he was observed by a neighbor. In fact, I think the neighbors said that it wasn't unusual to see his patrol car parked in her driveway on a frequent basis.

He was also caught on surveillance tape driving by a bank (I think... I don't think it was a convenience store, but who knows). They were able to put together the time frame of when he stopped by her house at 6-ish in the morning, when he drove by the surveillance camera, and how involved the fire was by the time it was called it in to the FD and when they arrived on scene.

They added it all up and determined that he had to have been the one to set the fire. Then they got other evidence on him, too, but I forgot what that was.

I can't remember what the motive was. It seems like the cop was married and she was tired of the being the other woman and told him to leave his wife, and this is how he reacted, but I very well could be mistaken about that.
