I am new to this on-line community and am seeking out any information anyone can offer with regards to helping me understand why some unsolved cases are "cold" while others seems to remain active? Specifically, I was a close friend of Heidi Martin. She was murdered on May 19, 1984 in Hartland, Vermont, at 16 years of age, and her killer has never been identified. I've found her name in a few threads on this forum but the facts (date/year and her age) were off. I am constantly wondering why her murder was not considered part of the "Connecticut River killings" when she was murdered in the same manner (multiple stab wounds and left for dead) in the same area and at the same time as many of the other women who's cases are still listed as active on the Vermont State Police website homicide page. I've read Phillip Ginsburg's "Shadow of Death" book on the unsolved murders of women in this area during this time period and I just don't understand how Heidi's murder, which was highly publicized, differs from the others in the eyes of law enforcement. I was 15 at the time and pretty much powerless. I suppose a part of me now wants to know what, if anything, can I do to move this forward? It's a big step for me to even write this post as some of you will understand. I remember everything about the days surrounding her death as if it were yesterday. Any help, advice or wisdom shared will be appreciated.
