I put the two maps (where body was found plus police map) together, but the police map doesn’t even indicate the location of the body so you have to make a visual guess based on other landmarks like the shopping center and Moller Ranch staging area that looks like a guitar head. It doesn’t look like the area was heavily covered except by the tip of the light blue loop. My best guess is that the body was slightly above the light blue loop. Use the line underneath the shopping center in both maps as a horizontal reference. It looks like the body was almost exactly due west of that line.
For other landmarks, on both maps, there’s a feature that looks like a toolbox above Diablo Canyon Road.
The SF Chronicle republished their map and looks to me moved the dot a little further south just a tiny bit. They changed the name of the nearest road also from Diablo Canyon Road to Dublin Canyon Road. Here is the link I have of it --

To me, on the SF Chron revised map it looks like the location is about due west from the end of Blessing Dr. [Side note: The City of Pleasanton used to call the end of Blessing Dr. by Morgan Dr. but changed the name in the 1990s. It looks like the City of Pleasanton never told the East Bay Regional Park District about the name change because Morgan Dr. still appears as the name of the street in the EBRPD Fire and Public Safety map that shows all of the park's Emergency Vehicle and Maintenance Access points].
Also if you look on the Alameda County parcel viewer here
Geocortex Viewer for HTML5 and search on 11025 Dublin Canyon Road, you can see two parcels divided by a red line. Plug the address into where it says Situs Address and search. You do not need to know the APN.
The termination of the North Ridge Trail ends near the top of the lower parcel (the rectangular parcel in the red box) and that is where the Sky7 helicopter showed the emergency vehicles parked. There is a label called Access Trail Tr on the map in the parcel viewer. It shows where two trails seemingly overlap, but it is one arcing up to the northern direction, and one continuing in the east direction that are at two slightly different levels. This corresponds to the picture CT runspired posted on his instagram and he linked on an earlier posting to Websleuths. He said the single track was about 10 ft away from where he took the photo. I am guessing this might be what law enforcement referred to in the press conference as possibly the 'game trail.'
The Alameda County parcel viewer seems to more or less show an accurate depiction of the trails for this parcel. It also matches the Fire and Public Safety map that you have to zoom in to see details here

On the other hand, the map that the city of Pleasanton has on its website of this parcel is completely wrong as it shows
lines for trails the EBRPD has not even built yet. I'm referring to the section F on the Moller Ranch Trail connection to Pleasanton Ridge that the city of Pleasanton has in its Trails Master Plan that it published on April 16, 2019. On this map, it has on the Legend of the map that solid lines mean existing trails. The lines for trails in the northern section of Pleasanton Ridge are depicted as solid lines on the City of Pleasanton map even though EBRPD has not even built these trails yet.
The map with all of the incorrect trails in the northern part of Pleasanton Ridge Regional Park in on page A-11 and is called the Pleasanton Trails Master Plan from the City of Pleasanton and the upper right corner says April 16, 2019. It is two pages and the section is called: F. THE PRESERVE AND MOLLER RANCH TRAIL CONNECTIONS TO PLEASANTON RIDGE and includes a map. It is on the City of Pleasanton website and I repeat, does not accurately portray the trails in Pleasanton Ridge Regional Park. Please do not rely on this map particularly if you plan to hike Pleasanton Ridge. It is so shockingly wrong, I have no idea how this ever made its way on the City of Pleasanton web page.
It seems to me that it is irresponsible and reckless for a public agency like a municipality to post a map purported to be of EBRPD Pleasanton Ridge trails where they have not had either had: 1) EBRPD review the map of trails for their property that the City of Pleasanton created to make sure it is accurate or 2) City of Pleasanton staff actually walk the trails themselves to make sure they in fact exist.
This City of Pleasanton map is so wrong about the northern grid of Pleasanton Ridge Regional Park that anyone relying on it as fact would get hopelessly lost including me. If Philip saw this City of Pleasanton produced map and used it as a reference, because it is so inaccurate, in my opinion there is no way he or anyone else for that matter could have figured out a way out of there.
