Let's review what we have seen with the law enforcement response in this case.
1. On Monday, December 10, WPPD had the initial press conference. CoP was asked if they were going to search PF's property, and he said to the effect of... "Oh hey, that might be a good idea. We'll have to consider doing that."
2. Tuesday through Thursday of that week, December 11, 12, and 13, there was some bad weather: it snowed and there were high winds and cold temperatures.
3. On Thursday, December 13, probably in the late afternoon or evening, LE applied for and obtained a SW of PF's property. It was sealed so as to keep it a secret.
4. On Friday, December 14, at first light (around 6am) and on a day with very nice weather, LE swarmed PF's property with 75 officers from WPPD, Teller Co Sheriff, CBI, FBI, animal control, etc.
Now you don't just get a search warrant one afternoon at the spur of the moment and have 75 officers magically appear the next day---these things are coordinated and planned better than a community theater production of Death of a Salesman.
So we can discern that:
1) LE is not dumb, even though they play dumb at times (Acting like the thought of searching PF's property had never occurred to them. The Chief of Police needs to work on his acting skills.);
2) LE was already making plans to search PF's home when they had the press conference on Monday;
3) any execution of a search warrant is going to be a well-coordinated effort, probably among several agencies, and there will plenty of manpower. You will not have any doubt that they have arrived. (If law enforcement shows up to the landfill with only one or two police cruisers, then you can bet they are still in the planning stage); and
4) they will look at the weather forecast when deciding what day to do any search that will take place outdoors.
It is supposed to snow in Colorado Springs tomorrow. Weather is kind of up and down over the next week. They might show up on Saturday, Sunday, or Monday, but then it is supposed to snow again on Monday night and be cold on Tuesday.
UPDATE: I see on Twitter that a couple of news sources are saying LE is looking at the landfill or is searching the landfill, but from what I can tell, LE has not actually shown up to start searching yet.
