TIMELINE UPDATED with presser info - no timestamps yet, since I was watching live.
MOOs
With the latest info, I suspect that they may either have phone pings, surveillance video, and/or witness testimony of MomLS at the location of this "specific dumpster." Taking a quick look around Google Maps, I noticed there are dumpsters at the
Pal's Mini Mart 1.4mi away. There's an
apartment complex 2.0 miles away with a dumpster in their parking lot. Hwy 17 is also about 2.0 miles away, and there's many more businesses there with dumpsters (Taco Bell, Dunkin Donuts, McDonald's, All-American Liquor,
etc), but since it's a busier area, you'd also run a greater risk of being noticed.
