Thank you all for your contributions to this thread. I follow missing persons cases from Missouri and never heard of Gwendolyn until the recent DNA match to her daughter, Alisha Heinrich. It's confusing because the facts state she was "last seen in KCMO" and yet, she wasn't. She was last seen walking along the interstate in Mississippi. Her case seems really under-reported. She's not even listed in the KCPD missing persons even though that's where she was from and last I checked, wasn't on Charley Project either. So I guess she's considered a MS missing person case, not MO.
So various reports state:
Gwen and Alisha were seen walking along the interstate in MS.
Alisha was "partially smothered" before being thrown from the bridge and then ultimately drowned.
A truck driver allegedly thought he saw Gwen's body floating in the same river.
The deceased boyfriend who returned to Missouri without them is a person of interest.
This would be a very plausiable theory... argument occurs car is stopped the woman gets out and takes the child and starts walking ....
1-10 is heavily traveled I'm sure someone saw something but of course you would have had to live locally and see it in the newspaper or on the news. Someone traveling through to another state would not have even known.
I agree that someone had to have been witness to something as well, because they were seen walking, and allegedly Gwen's body was spotted, so a timeline was successfully put together. Is the hypothesis that the boyfriend threw them both off the bridge? It seems like a spontaneous thing to do if there was such a risk of being caught. Otherwise why not just drive them to the woods and kill them there with the convenience of having a car etc..
Since Gwen was never found, maybe she was never near the water. I'm by no means an analyst of how bodies travel down a river but it seems Gwen's would have been found first had she been there. Unless the truck driver was mistaken that is. And if it was the boyfriend, he wasn't even with them when they were seen walking, unless he went back for them like was previously suggested. Just all around strange case.
