Ernestine Perea was found dead in her bedroom of a single gunshot wound.

The gun was by her side.

After examining the forensic evidence, her death was ruled a homicide.

But could that same evidence be interpreted differently?

One man's life hung in the balance.

In 1979, Martin Freyaw's entered the United States illegally from Mexico looking for work.

More opportunities for the rescue family, better way to educate your kids, or better life.

Freyaw's landed a job at a local marble processing plant in the rural town of Wheatland, Wyoming.

Two years later, he met 24-year-old Ernestine Perea, a divorcee with a young daughter.

They had two children of their own, a boy and a girl.

Ernestine and Martin decided to live together and rented a mobile home on the edge of town.

But they also fought, mostly over insignificant matters, says Martin.

On July 5, 1984, Ernestine spent the entire day out with her children and didn't arrive home until 10.30 that night.

Martin put the children to bed while Ernestine went to sleep in the couple's bedroom.

That night, Freyaw slept on a sofa bed in the living room.

Around 1 o'clock in the morning, Freyaw's was awakened by one of the children crying.

She was like, same mommy, mommy, get up.

Turned a lot on, and that's when I saw she was laying in the road right down the floor.

I actually had the gun next door.

Ernestine was dead from a gunshot wound.

I see blood in her stomach.

You know, when I was walking out with Freyaw, I saw also blood as blood in the wall.
