In the recording, you hear the car door opening and Holly and Will getting inside.

You hear the car's engine turning on, but then you hear Will yelling, what the F, which is immediately followed by several gunshots.

As the shots are going off, you hear high-pitched screaming with Holly yelling, please God help me, help me.

You hear Holly continuing to scream and yell while Will's voice suddenly goes silent.

Then you hear the car drive away while the sounds of Holly screaming get more faint until they completely fade away.

This footage was incredibly upsetting for anyone who viewed it.

Even the investigators who watched that footage were disturbed and had a hard time listening to it.

It was just horrible.

Based on what they heard in this footage, it's obvious that someone came to the apartment where Holly lived and somehow knew that both her and Will were going to be there.

They were then confronted by this person as they got in their car and were shot.

Then the shooter most likely got into the car, then drove them off the road and into a ditch, maybe in hopes that it would take longer to find the car.

Now, like I said, early in the investigation, detectives started looking into the text messages and social medias of both Holly and Will.

There, they discovered Holly's work as an escort as well as how Will reacted to this information.

They found that Holly had a whole list of clients and they saw how Will was reaching out to these men, all threatening to expose what they were doing to their wives.

Well, there was one client in particular who stood out to investigators.

This client was 46-year-old Eric Charles Mund.

Now, Eric Mund was raised in a very well-off family who owned and operated a Toyota car dealership out of Austin, Texas.

His grandfather, Charles, built up the family business from nothing back in 1957, then went on to expand and grow the business into an empire of multiple dealerships, earning the family wealth that expanded multiple generations.

The Mund family is very well known in the area not just for their vast wealth, but also for their social status, involving themselves in the highest social circles all around that area.

Eric was married to his wife of 22 years, Sherry, and together they had two children.
