There are currently 21 unsolved and open cases in Weld County right now.

These cases are cold, meaning they are no longer being actively pursued due to a lack of evidence.

However, that doesn't mean they are unsolvable — it's always possible that someone knows something. This is why we'll be exploring these cases in a series for "Tuned In to NoCo." 

But for now, here's an overview of the cases we'll be talking about:

1. Yvonn Rabb

Yvonn Rabb was a prostitute working in the Five Points area of Denver, when her body was found in a ditch near Weld County Roads 8 and 11 on November 15, 1981. She was last seen the night before in an alley near Big Al's Bar in Denver.

A witness heard a gunshot in the alley that night, and authorities suspect that her murder was tied to a drug transaction. Suspects were identified, but no one has been charged with her murder.

2. Margorie Sue Fithian

Margorie "Margie" Fithian was last seen with her 18-month-old son by her uncle at a bus stop in Denver. She was heading to Greeley, but her body was soon found in a ditch in rural Weld County on June 24, 1975.

She had been shot to death. Her son was alive, unharmed, and found near her body.

Witnesses saw a yellow or tan two-door car in the area. Robert Davis, Vern Hudson, Larry Hernandez, and others have been identified as suspects, but no one has been charged with her murder.
