I personally found a lot of debris: cigarettes, water & soda bottles, trash, and other debris <modsnip - hinting at add'l info> at PTL during the week that the initial search was performed.
I was baffled as to WHY the specific area around where HE's car was found was not spotless from all the potential trace evidence scattered about the area was not collected!!! All in plain sight!
HCDP was focused on the Waccamaw River and in the river itself when I was there.
This has always been a big irritation with me during the start of the search/investigation.
