Eric Richens' sister approached one of the investigators in the driveway and said,

I think Corey had something to do with it.

Really?

They assumed that she was involved in his death, so they had to build their case.

When you have a family member pointing out a spouse right away, that is a big red flag.

A big red flag.

Another red flag?

That huge property, the so-called Midway Mansion.

This 20,000 square foot mansion that sits on 10 acres at the base of the Wasatch Mountains was one of the properties Corey wanted to flip.

But that would cost millions of dollars and was apparently a big source of contention between Corey and Eric.

Remember, Corey said they were celebrating the Midway Mansion deal the night before Eric died with those Moscow mules and lemon drop shots.

The family told investigators Eric was reluctant to buy that home.

Corey was really hot on getting that property and flipping it, but Eric, not so much.

Eric's sister was stunned when she learned Corey was going to close the deal just hours after his death.

The family was also troubled by Corey's initial story, that Eric died of a lung fungus, just like the one that killed his mother.

She told even Eric's dad that they found this same fungus in Eric's lungs, which was a complete lie.

Even Eric had been suspicious of Corey.

He told his family about that Valentine's Day sandwich that made him sick just two weeks before his death.

I spoke with a number of people who he had contacted regarding his health condition that day.
