Our card this week is Rose Burkert and Roger Ackison, the Nine of Diamonds from Iowa.

In September 1980, a holiday in hotel in rural Iowa became the scene of a shocking double murder.

A couple was found dead in their hotel bed covered in lacerations,

and the scene around them is one of the strangest and most puzzling I have ever come across

in all my work. It's one of the reasons that this case has gained notoriety over time.

I mean, to this day, the hotel where the couple lost their lives

is still visited by true crime fanatics. Despite multiple suspects and three agencies contributing

to this investigation, no one has ever been arrested or charged in connection with Rose and

Rogers' deaths.

The Do Not Disturb sign had been on the door as early as 8 a.m. when her staff checked.

But well, after checkout time had passed, one of Ida

staff members tried entering the room. As soon as she cracked the door open, she noticed clothes on the

floor, so she assumed that the couple were still sleeping and she left. Then, at some point,

she notified Ida, who now had to go be the bad guy and kick this couple out.

So at 1.15 p.m., Ida headed through the outdoor breezeway to room 260 at the very end of the hallway on the second floor.

Back then, digital key cards weren't really a thing, meaning Ida had to use a physical master key to unlock the door
