And none of the neighbors had reported seeing anything unusual around the time of the explosion that would help them narrow it down.

So now, as Detective Shepard sat down across the interrogation table from Kemp's ex-husband Todd Wenger, he started with some general questions about his relationship with Kemp.

And Todd seemed a little nervous because he kept wringing his hands while he spoke.

He said that he and Kem did fight about child support costs.

And he said he had been very frustrated with her because he didn't feel like she was always fair during their divorce.

But he insisted that that did not mean he wanted to hurt her.

He said their problems were common for most divorced couples.

Shepherd did not put much stock in that assertion because in his experience, divorce or breakup plus money was a very good motive to hurt somebody.

So he asked Todd where he'd been all day on the night of the blast.

And at this question, Todd definitely appeared to relax.

and he launched into a very detailed explanation of all his movements.

He said he'd been with his daughter and his new girlfriend, and both of them would definitely vouch for him, along with several people who had seen them during the day.

By the time Shepard sent Todd home, he really wasn't sure which of the exes, Todd or Dale, he thought was a better candidate for his killer.

Both had clearly been fighting with Cam or had real tension with Cam, but both had alibi witnesses.

So, Kem's fiance, Kurt, might have had the opportunity to plant the bomb if it was set shortly before the explosion, but he had no clear motive.

As for Todd and Dale, they seemed to have plenty of motive, but no real opportunity.

And so Shepard decided his next move should be to talk again to Kem's family.

Maybe they would be able to help him sort out his flawed suspect list.

On Sunday evening, so almost 24 hours after the explosion, Detective Shepard knocked on the door of the home where Kem's sister, Joni, lived.

Now, by this point, another officer had already been there to tell her and their mother, Cricket, about Kem's death.
