LE may possibly have their suspect and are simply awaiting testing results, funerals to respectfully be over and more evidence to obtain. It isn't unusual for LE and prosecutors to want an open shut case. That often means gathering more information/evidence and holding off in an arrest with survelance in place. That being said there are countless scenarios that would work with this murder from a motorcycle purposely dumped to offer an alibi and explanation for cuts and bruising to an ex boyfriend or an obsessive person from the past that saw her the night before when she was having dinner with her father at a local restaurant. She grew up in the area and probably knew countless individuals who lived in the area. The burning of her body is gruesome and troublesome but possibly just represents an attempt by someone ,not familiar with forensics to destroy DNA. It sounds like perhaps the perimeters of her body lit (Head, hands, feet ). I have no idea what the extent of the burns were but in my opinion the perp left and the fire went out before she burned completely. Serial Killer ? Perhaps but I think this person knew her or certainly had seen her before, he's local, familiar. Opportunist definitely, random unlikely. That being said there was a serial killer years ago in the South ( Florida I believe ) that would randomly drive around looking for girls walking. A book was written I believe called " When I See A Girl Walking ". Monday Morning Sleuthing is just opinions of would could/ could not have happened. My opinion in no way implies the motorcyclist is guilty of anything but a spill on a bike or that an ex boyfriend targeted this individual. Respectfully Crime Forums are just ideas, people coming together to discuss a tragedy and possibly a resolution. Hopefully the person will be caught, confess and the community can rest. But sadly the Marcotte family may never have that peace again. Thoughts, Prayers and heartfelt condolences to the Marcotte family, friends and community.
