I haven't delved too much into the cases in the Wilmington area but I have read reports and heard locals recount that upwards to three woman have been dumped by the side of River Rd and College Rd, IIRC. One or two of the woman were found near Monkey Junction, IIRC, one just off the road and either in or near the parking lot of a pool hall. River Rd is a desolate rd that cuts from downtown Wilmington, along the river's edge toward Carolina Beach Rd (which is also called College Rd in different stretches.) It begins as I40 and once you near UNC Wilmington it becomes College Rd and then Carolina Beach Rd. I was under the impression that Amber C had lived in the Wilmington area before going to Florida and then onto LI, NY.
Many here have wondered about the Daytona Beach, AC, and LI being connected.
Philadelphia also has, as recently as last December, a string of unsolved prostitute murders. All of these places are along I-95. Even Richmond, VA has quite a few woman dumped along I-64 E & W of Richmond. I-64 cuts over I-95. There has been speculation that the LI SK commits these murders in relation to the seasons or just before or after holiday weekends which could mean that the SK travels perhaps via the I-95 corridor.
I think I know who you are considering, as a person of interest in the AC murders, and if it is who I think it is I have been concerned about him since he first spoke publicly. One article even said that his kids were in foster care in the Philadelphia area. Other articles said they were in foster care in NJ. But either way that gives him good reason to be in both NJ and Philadelphia. The comment that never sat right with me was that he said he, "was certain that it was someone she knew." (paraphrased) and the other comment that they were supposed to hook up again in a week (the week after it is said, she hopped on a bus and out of LI and back to AC) "but it was a week too late." Something about that comment and finding out that before going to LI with her that they stay at the Motel where she was likely murdered really bothers me. I wonder if they stayed in room 101.
