Jason McDermott

One by one, investigators had cleared all the other potential suspects, Colin McCauley, David DiNarda, and Morgan's boyfriend, Jason Skarnackia.

Jason McDermott pleaded not guilty, and Morgan's family knew a circumstantial case might be a tough sell to a jury.

No DNA?

No video of him committing the crime?

Were you worried?

Prosecutor Dennis Barr tried the case.

What picture did you paint of Jason McDermott in that trial?

Somebody who was seeking, in every way, shape, and form, a romantic relationship with some female individual.

Barr says the true magnitude of that obsession became clear when investigators did a deeper dive on Jason's phone.

Detectives also found images of Morgan.

that Jason had recorded secretly.

Some of those were at the facility, and one of those videos actually was at her house, and he was recording her behind during the whole conversation.

The prosecutor says it was Jason's obsession that drove him to look through Morgan's phone.

That was the straw that broke the camel's back for Morgan.

Barr told the jury Morgan's rejection and withdrawal of her friendship pushed Jason from obsession to homicide.

His co-workers said Jason went into this downward spiral.

Around this time, Jason texted a co-worker, I haven't been this bad in years.

I feel like I'm constantly holding on by a thread.

Over the next couple of weeks, he attempted to reconcile with Morgan via text.

He even wrote her a letter.
