Does anyone remember these stories or if there have been any updates on them?

The first - A man living in a small town in Montana (I think) starts telling people he is going on a journey into the ominous mountains nearby. So, he tells people he is going in, and is never seen again. He had no supplies with him of any kind, and was only wearing a jacket, jeans and boots. They searched the mountains for him, but when I last saw the case, it was still unsolved. The guy was kinda hippie-looking, with long grey hair and a black and grey beard.

The second - A man is killed in his house by his girlfriend's ex-boyfriend. The ex-boyfriend left a little pile of cigarette butts about 70 feet from the house. The family of the victim thinks the girlfriend had something to do with it, but she maintains her innocence. The murderer (I think he was indian) hasn't been seen since.

The third - A group of teens are hanging out at a park late at night when a car drives by and shoots at them with an AK-47. Three (I think) of the teens died, and only one survived. The suspects were later identified as two known gang members and have not been captured.

If anyone could provide more details about these cases, I would appreciate it :)

I remember the second one. The murder victims name was Todd Kelly I believe and the girlfriends name was Kristi/Christi sp? The murderer was originally from Bangladesh. I have never heard an update on this one.

Did the third case take place in Houston? It sounds familiar...except i thought that their were 3 teens hanging out at the park and only one (girl) died. In this case, i think they believed that the gang members fled to Mexico...not sure about any updates.

Yeah, that may be it...sorry, my details are kind of sketchy :)

The girls name was Kristi Martin. My recollection is that she was out on a double date and the 4 of them went to a local park. This gang thought the park was their turf and no one else could go there and started shooting at the car. It seems like it did take place in Houston.

Does that first case sound familiar to anyone? It's an older one, I believe.

Yes, the man's name was Keith Reinhard. If you look at the post titled "unaired segments" more detail is given on the story. Hope this helps!
