Patricia Lang was 36 years old when she took a job in Des Moines, Iowa, to be closer to her family.

She was relocating there from Denver and needed a place to stay until our new apartment was ready.

So, in August of 1993, she booked her room for a week at the Holiday Inn in West Des Moines.

When Patricia didn't show up for work on Monday, a member of the housekeeping staff was sent to her room to make sure she was okay.

Patricia was not okay. The housekeeper found her body in the hotel room. Patricia had been murdered.

There was also a piece of cloth tied around her neck.

Patricia's body was on the floor, and the room had been ransacked.

Investigator Bush tried to make sense of what he saw at the crime scene and determine a

In the room was the victim's purse or clutch wallet, and I think there was over $200 yet,

There was no indication of a robbery-type situation.

Bush continued to process the crime scene.

and the blanket she'd been wrapped inside.

He was accompanied by Agent Jim Saunders from the Iowa Division of Criminal Investigation.

Agent Saunders wanted to determine how the killer had entered the room.
