We know for a fact that Watts disposed of items – including at least one blanket – in a dumpster at or near 6507 Black Mesa, which was under construction at the time.
In the K9 search below, the dog is barking throughout the time they’re in Black Mesa road. At 06:10 in the clip below, the dog handler says: “He’s picking up scent from the house,” which we now know was true.
Notice all the red dumpsters lining the side of the road going down Black Mesa.
At this time when the dog is barking, they’re standing right beside a large, red construction dumpster. They’re also standing right beside a house that’s under construction. The cops don’t seem to know or inquire about the schedule for when the dumpsters are emptied, but it was each Tuesday, possibly in the morning prior to or after the search.
The red arrows denote the route Watts took on August 13th. The green is the route he should have taken home.
In retrospect it’s unfortunate that law enforcement weren’t able to coordinate with the K9 unit while they were out there to specifically look at 6507 Black Mesa, based on the GPS data. From the discovery [page 555] it appears the GPS data was only provided in the late afternoon or early evening of August 14th, by Tony Huskey, Anadarko’s regional security manager.
It appears the cops only inspected the scene properly on August 22nd, more than a week after they’d received the data. Officer Lines’ report neglects to mention the activity along Black Mesa, or the dog handler Jayne Zmijewski ‘s comment about the dog picking up scents from the house.
There appears to be a second alert, or certainly interest, in Bella’s bedroom. It’s at about 19:30 in the clip below.
