Harvey Guillén

Except Jim said he wanted the shirt to use in his garage, like a shop towel.

Emma's not the only one who helps authorities crack the case.

They also speak to Glenn McSparran, the driver who discovered Molly's body.

They're quite interested in what he remembers because, if you'll recall, he saw a second vehicle there earlier in the night, which means the person he spoke to might be Molly's killer.

Glenn remembers that this person was most likely an older man, but he can't be sure.

That's just his best guess, based on how the person sounded.

It was too dark to see clearly, and he had bright headlights in his eyes.

So he also doesn't know the make or model of this person's car, but if he has to describe it, he says it was like a grandma car.

And yes, that description is a bit subjective.

At the time, Jim is driving a Mercury Sable, a type of car that was discontinued in 2009.

It's your basic sedan, but it's not not a grandma car.

Detectives also get an assist from Jim's wife, Melanie, who, by the way, is a delightful preschool teacher.

Once she has time to process the info dump, Melanie has to admit, Jim does seem like the kind of guy who would resort to murder.

The more she thinks about it, the more it sounds exactly like the kind of selfish thing he would do.

And she still has his real cell phone, so she hands it over to the authorities.

Looking at Jim's phone side by side, investigators find another bizarre clue.

After Melanie hands over Jim's regular phone, detectives realize that shortly before Molly's murder, he sent some bizarre text messages

to himself.

Using his burner phone, Jim texted this to his regular phone.

Have a meeting tonight at 8.
