|You can see two distinct tracks leading up to the left side
of the main two blue tarps
“The two trenches are symmetrical and exactly the same distance apart. We measured the distance between the tracks and I called my friend at a machine hire rental place to ask what kind of machine has tracks 67 inches apart. He said it would be a Bobcat. There is a quarry just up the track from the site so a Bobcat would not raise a red flag. The guy would had to have had a four-wheel truck that could drive a trailer into there.”
I started asking around and doing a lot of researching to figure out what would leave tracks 67″ wide.
Please keep in mind I do not know if Michael measured from the far side of the track to the other far side, or from inside to inside or even middle of the track mark to the middle of the other track mark.
A Bobcat track width, meaning the measurement from one tire to the other is 40 to 50 inches depending on what type of Bobcat. There is one a S175 Skid Steer Loader that has a track of 5.5 feet which comes out to 65 inches. This is pretty close to the 67 inches but you would have to put it on a trailer to get it to the location. If the trailer was backed into the shallow grave location the tracks would be too wide. So, the trailer would have had to have been parked elsewhere and then the Bobcat driven over to the area where the graves where made.
I still wanted to check out different vehicles to see if it was a vehicle that made the tracks. I kept finding that most vehicles were not wide enough. See the list below for Fords:
1965-1966 Mustang 57.25 inches

More digging and I find that most four-wheel-drive pick up differentials are 65 inches wide. Getting closer, but not 67 inches.

You can see that these are not quite large enough, and a lot of vehicles can be eliminated as the cause of the tracks. So, I checked on some super trucks.
A Toyota Tacoma 2011 track width is 63 and a Ram truck conventional cab is 65.7 front and 63.4 rear, 65.3 or 65.6 front, and a 64 for single rear wheels, and 68 for duals. All under the 67 inches.
A Ram club crew cabs, w150 is 65.7 front, and 63.4 rear, w200’s are 65.3 for club cab, and 65.5 for crew cab, and 64.0 rear for both, which is also under the 67 inches.
They I checked on a new Chevrolet Silverado and it has a front track width of 68.8 and a rear track width of 67.3 (finally something that is pretty darn close). A 2010 Chevrolet Silverado front track is 68.1 in and 67.0 in. rear track. (The rear track is an exact match.) Then the Ford 250, and 350 front wheel tracks are 68.3 and the rear is 67.2 inches.
Then I started thinking about Joey and Summer’s vehicles. A 2002 Isuzu Trooper’s width is, front 59.6 and the rear 59.8 so we know that this vehicle was not the one that left the tire tracks, but what about their truck. What is the track width for those tires?
The McStay’s truck was a Dodge truck, so I looked at the track width for those vehicles. The track width of a 1991-1996 Dodge truck is 69.4 inches.
So it looks as though the closest match is a Chevrolet Silverado or a Ford 250 or 350.
If we go by what Michael is saying, could the person responsible for the deaths of the McStay family been driving a truck with a trailer in back with a Bobcat sitting on it?
Checking on an average trailer that would be used for a bobcat, they are 18 foot in length and the width is average about 77 to 80 inches. As I mentioned above, this is too wide for the 67″ wide tracks.
The SkidSteer Bobcat would be exactly the right width for the 67 inch tracks, but the the trailer hauling it would have wider tracks. The only way this would be a great match if we assumed the trailer and the truck towing it was parked elsewhere and the Bobcat was driven off the trailer and it made the tracks as it was digging the graves. But this leaves another big question. Why were the graves so shallow if someone was using a Bobcat to dig them. With a Bobcat it would have been easy to dig the graves so deep that nothing would have ever been found. I believe because the graves were so shallow they must have been dug by someone using a shovel.
This leads me to the conclusion that it was probably a Silverado or F250 truck, possible white (as a neighbor mentioned seeing a white truck) that was used to transport the McStay’s.
Whether they were transported in the cab of the truck or the bed is still unknown, but if in the bed there would have had to have been something in the bed of the truck to cover them, like firewood or a tarp. I do remember hearing there was sheets and blankets missing. Could Summer have been attacked and strangled to death in the home, then her body was put into the bed of the truck wrapped in sheets and blankets. To get Summer into the bed of the truck unnoticed, the truck would have to have been parked in the McStay garage but we know that was not possible because the garage was full. Maybe the person would have had to have waiting until dark to put her body in the truck or possible early in the morning before the sun came up.
I heard that one person had been found in the grave with their hands tied, if this is true, could it have been Joey because Summer had already been killed? With Summer in the back of the truck there would be room for the two boys and Joey in the cab with a driver.
If we assume the act was not premeditated but maybe someone that got angry, the person had a limited amount of time to get back to their home and establish their routine before anyone noticed they were gone. If they left the McStay house by nightfall (in February 2010, the sun sets around 5:20 p.m.) and drove to Victorville, which is an hour an 40 minutes a way (with no traffic) is there a possibility they could get back in time to drive the Trooper to the border at 7:47 p.m., when the surveillance video show’s it leaving the neighborhood? Not likely. They would not get to Victorville until at the least, 7:20 p.m. and then they would have to dig two holes, with a shovel, which would take at least an hour to do, and then drive back to the McStay’s home to pick up the car. By then it would be after 10 p.m. But let’s also consider that the graves could have already been dug.
Note: on 6/11/15 – Defense attorney Mettias stated there were two different set of tracks left at the graves. Is it possible that one set was made when the graves were dug and the second set was made when the bodies were put into the graves? Thus, two different vehicles?
Add on the time to park the truck several blocks away and get out and walk to the McStay home in the dark and jumped into the Trooper and drive it to the San Ysidro border it would be at least 10:30 p.m. by then and we know the Trooper left earlier that evening. The murders could have happened much earlier in the day than was first thought.
|I wonder if the police thought to check the trolley station video for anyone getting on the trolley the night
the Trooper was left at the border.
Was the whole family together or is it possible that Summer and the boy’s were abducted sometime that evening and the person used Summer’s phone via a text to tell Joseph to meet them at a location? Maybe.
Now that we can rule out a Bobcat was used, then a shovel would have had to been obtained. Has anyone checked to see if the McStay’s had a shovel and if it was missing?
If the tracks were caused by the killer’s vehicle, because we know the track width of both of the McStay’s own vehicle does not fit, then we can only hope that the police hurry up and obtain search warrants so that vehicles can be searched for evidence and DNA. We can also probably cross some people off the list that do not own a vehicle, let alone a truck, unless they borrowed someone’s truck during the time.
Lastly, many people have commented on how in the world could tire tracks still be embedded in the ground after 3 years. I believe rain may have helped. On average, February is the wettest month for Victorville, but in January 2010 it rained more than February 2010. Add in the weight of the truck with five people and possible firewood and that ground could have been soft enough so that tire tracks left an impression, that have remained to this day.
