Our card this week is Blanca Acevedo, the seven of clubs from Arizona.

In June 2010, 50-year-old Blanca was navigating a life of quiet chaos when she was found

murdered in a building set of flame. The brutal case of overkill quickly went cold for the

detectives on the case.

But could a letter found on Blanca's bedside table have held the key to finding her killer all along?

It is one of the several clues that new investigators are chasing down to solve this 15-year-old murder.

I'm Ashley Flowers, and this is The Deck. On the afternoon of June 27, 2010, a man named Robert Williams was leaving a meeting at a church in Phoenix, Arizona, when he looked up and saw smoke rising from a nearby area.

Extra concerning was the fact that where the smoke was coming from was right near where his sister worked.

So Robert jumped in his Buick and drove straight toward the billowing black smoke.

But when he pulled up to 3421 West Orangewood Avenue, he was relieved to see that his sister's

office looked just fine. It was actually the nearby New Way Realty office that was on fire.

As Robert got close to the building, he saw a man beating and knocking on the window in

desperation. He was yelling for anyone inside the office. But Robert knew that they needed help,

so he called the fire department. When firefighters arrived shortly before 5 p.m.,

they discovered more than just smoke and flames.

In fact, when the first firefighter entered New Way,

he tripped and stumbled on something, or rather, someone.

Just a few feet inside of the building they could see what looked like a person laying on the floor, unresponsive.

She was removed from the structure.

She was covered with a blanket right there in the front of the business.

She's pulled outside through the front main door,

out into sort of a grassy area, or actually right out front.
