This case was built primarily on four factors:
1) Robert and Cristin were mistaken as to exactly where they were when calls came in from Becky 9/17/2018-between the times of 6:53 & 7:34
2) They turned their phones off (or didn't ping a tower, for whatever reason), and then their phones ping again, close to the same time
3) There was a business card found over 200 yards from the Friedli home that had DNA which excluded Robert, but could not exclude Cristin
4) Phone pings place Robert and Cristin at a location where they might have driven to the Friedli residence. if they continued to Highway 74, and ascended up that highway
Because this is a website for sleuths, and I have read some great analysis here, I'll give those interested, something to ponder.
Regarding 1):
Robert and Cristin were mistaken at to exactly where they were when the calls came in from Becky
This error in recollection was actually very small. It was just a mile, or so, difference between being at Cristin's home in Cathedral City and driving in route to Sacred Heart Church (Palm Desert). And if they were driving, and talking to one another while this was going on, it seems it would be easy to confuse.
But here is a question: How often do any of us recall where we were when a call comes into our cell that we choose to ignore?
[Of the calls that Becky made to Robert and Cristin that night-from 6:53 and after (and she made all the calls except one-Robert initiated NONE of the calls), all the calls went to voicemail. And the phones pinged towers for all but the last call. So these calls could not have been received while the two were ascending 74-there is no cell service there.]
And why would Becky, who had made that drive from Palm Desert to her home hundreds of time, continue to call Robert and Cristin if she thought they were headed to her? She knows there is no cell reception on 74 once you ascend-and there won't be service from that point forward, because there was no cell reception in Pinyon Pines either.
It seems much more likely that there was a cancellation of the plans to hike (during an earlier call), Becky kept calling because she knew that Robert was in a location where there was cell reception, and Robert and Cristin turned off their phones because they didn't want to talk to her anymore.
Regarding 2):
Robert and Cristin turned their phones off and on again, around the same times
Basically the resolve to this is to be had in the response to number 1.
If you look at the phone log (I post this below) Becky called Robert and Cristin a combination of 8 times. And seven of these calls occur after 6:53, which would have been too late for Robert and Cristin to get to her home for a hike. The sun set around 6:30ish that night. Becky had to work that night. Is she really going to go on a hike that starts at 7:30 or 8:00? She was more likely calling for another reason. And we'll never know what the reason was, because Robert and Cristin, being teenage boys, just let the calls go to voicemail.
Key aspects of Robert and Cristin's alibi were never looked into by LE. Including the timestamp on the x-box game they said they played. They also said they stopped at an AM/PM, and LE waited 13 days to get the surveillance recording. It was taped over by then. In addition, no one in the family who could have verified that Robert and Cristin went to certain homes, was ever questioned. (One of those witnesses passed away in 2008.)
But all the above would explain why their phones were off together, they were busy, playing xbox, etc. And it wasn't until later that they chose to check their messages. Not really all that suspicious.
Why give an alibi that could be so easily negated? Robert and Cristin would have zero way of knowing the cops wouldn't follow up.
Regarding 3):
There was a business card (the purpose of which was to recruit volunteers, interested in pro-life endeavors) found over 200 yards from the Friedli home. It contained DNA which excluded Robert, but did not exclude Cristin
There was DNA on the wheelbarrow handles and Becky's socks, as well. This DNA, is on items where there is no question that they are at the scene of both the murders and the fire.
The business card, which is the only DNA that comes close to matching either Robert and Cristin, (and seems out of keeping with ownership by a 17 year old boy), is one that comes from Diocese of San Bernardino (
Diocese of San Bernardino: About the Diocese). That card is distributed to parishes in the cities listed below, plus Palm Desert, Sacred Heart:
Adelanto, Chino, Alta Loma.Chino Hills,Anza,Coachella,Apple Valley, Colton
Banning/BeaumontCorona, Barstow, Crestline, Big Bear, Desert Hot Springs, Bloomington, Eastvale, Blythe, Fontana, Cathedral City, Grand Terrace,Guasti
There were two labs that found no match, the third could not exclude Cristin. Then suddenly at trial, that match is more exact. But how? There was no retesting. The DNA sample had been exhausted. How suddenly is there a new outcome, when no re-testing was performed? I can't figure it out. If you know, please enlighten me.
But the real question is, when and how did that business card even arrive at that spot? No one knows. So DNA on Becky's socks and the wheelbarrow handle, that isn't a match to either Robert or Cristin, is ignored, and a card--that could have dropped from a pocket a day before, a week before or even a month before--takes center stage. Why?
And then there is this little thing that everyone in forensics is talking about: Touch DNA! That doesn't appear to have been factored into the equation of possibilities by investigators, at all.
I don't get it.
Can someone here sleuth this for me?
Regarding 4):
Phone pings place Robert and Cristin at a location where they might have driven to the Friedli residence, if they had continued to Highway 74, and ascended up that highway.
But there is no proof that they did continue onto 74. None.
And as I mention above, alibi evidence that could have easily been followed up on, wasn't.
And sector data (that basically shows from which direction a person pings a tower) was never asked for by LE. So no one has any idea from where these pings originated: north, south, east, west, who knows?
Gladiator Forensics generated some fancy looking, multi-colored maps, intended to show the coverage of each tower pinged; but without sector data, what do they really indicate?
These maps do not appear to delineate the coverage of each individual sector, of the antennas being tested (the method used to generate these maps is commonly known as a "drive-test", and was designed to monitor subscriber coverage. The use of this "drive-test" for criminal trials and is different than the type of map more commonly used. The accuracy of this type of testing as it relates to historical ping data does not seem certain. In real-time, it appears to be accurate, but with all the factors that go into why a cell phone pings a given tower, looking back 12 years, by way of a test designed for real-time measurements-seems a little iffy. At least it does to me.)
AND, did Gladiator check to see if any of the antennas in question were either manually or digitally down-tilted, in a small or big way, in the past decade?
Alter the down-tilt of an antenna, even slightly, this will alter the coverage. (This isn't something that necessarily requires a building permit.)
I'm afraid this post is getting too long. So more on the ping evidence later. And then there was some very iffy witness testimony...
This case is rife with contradictions.
Maybe there is still a mystery to be solved here...
