What are your thoughts on how a teen could have done this? I have a hard time believing a teen would be an organized killer as some experts have suggested. I think a teen would be very sloppy, leaving clues all over the place.
The killer appears to have been careless and appears to have left clues all over the place.
But that's not why I believe the killer is young. The cross just looks like what a young person would wear, and the way the perp appears to have marked his item with his first initial, but not his last makes it look like he still lives with his brother and maybe even his mommy. It also looks like he and his brother are still immature enough to argue over a crooked one dollar wooden cross, hence the need to mark it with an inititial.
