I'm not referring to the Aileen Conway case. I'm looking for information about a case that occured in 1987 and was probably profiled on UM in 1988-1989 or so. This lady was found dead in her burned car. Police knew that she had some problems with her son, and suspicion had landed on him, but they could never prove anything. Does this ring a bell to anyone?

Hey! It may be the Kathy Bonderson case you're referring to. One of my all time favorites UM segments. Anyway Kathy's son was out way past curfew so she called in sick to work and took off driving looking for him in the middle of the night. He claimed he even saw her car on his way home. She was found shortly after dead and her car engulfed in flames. Is that the one? If so here is fairly recent post about her:

Yeah, that's the one! Thanks!

This is a brief overview of an article that appeared in a South Dakota newspaper in Nov. of 2005.

A newly formed team of state investigators will look into old, unsolved homicide and missing-person cases, with hopes that new witness interviews and technology will generate fresh leads. The "cold case" group's first project is the reopening of an investigation into the October 1987 death of a New Rockford woman, Kathy Bonderson, 35, whose body was found in her smoldering car just west of town. :)

This is good because her case definitely seemed to be an unsolved mystery with few leads.
