Cellphone As Key Police Evidence

There's a good look at how cellphone triangulation works in the Daily News today, in relation to how police were able to determine that the Imette St. Guillen murder's "prime suspect" Darryl Littlejohn was in the vicinity of where her body was eventually found. We'd been curious about how the technology works (sure, we'd seen it "used" in TV shows or mentioned and got the basic idea), but we didn't realize locations can be determined even without phone calls being made. And that seems to be the difference with Littlejohn's cellphone information - the NYPD hasn't outright said he made calls in that area because they may have pulled his whereabouts by overalls pings to cell towers. We wonder if the police used that technology in the murder of Catherine Woods, the Upper East dancer-stripper, in which her boyfriend was arrested (he had made multiple cellphone calls to her before her death and, then, suddenly nothing).

In other St. Guillen case news, the NY Times says the police have been unsuccessful as yet with tying Littlejohn to the other rapes in Queens and Brooklyn. And Brooklyn Assemblyman Felix Ortiz proposed "Imette's Law", which would require any establishment with a liquor license to install cameras at all entrances. Bar owners are upset, because that's an additional cost in the thousands, but the politicians feel that the fact many violent disputes occur at bars outweighs that complaint. It'll be interesting to see how bar security changes in the next year - some bars actually scan licenses after incidents.

Note to self: Turn cell phone OFF before committing any crimes.

Or leave it at home. But, really, the plethora of information about crimes available through the media and TV programs makes me wonder about the whole "is media/TV helping criminals" angle.

RE: "Is media/TV helping criminals" angle...

Totally agree. Next time we'll just get a psychopath who remembers to turn his phone off and even though the police have a hunch he did it, they won't be able to prove it. And he'll get off...

Then again, is it the media's fault, or ours for our endless need to hear every gory detail about these types of crimes? After all, if those stories did not sell and we did not buy those papers, the media surely would be writing about different things.

So maybe (sadly) we are getting what is coming to us...Maybe in the end the monster is us and not the media.

That may very well be the case.

Sometimes MacGyver used household chemicals to create poisons, explosives and what not. To describe how he did it in detail would be dangerous just in case a fan copied something from the show.

The details were intentionally fudged so the viewer didn’t know how MacGyver concocted the chemicals. TV shows these days should do the same. (In regards to the CSI criminal strategies anyway)

But then it would take away at the coolness of the show if the criminals were dumbed down.

dont kid yourselves. if reality were anything like CSI, these guys would have already burried Littlejohn under the jailhouse. as it is, they were lucky to find that speck of blood because without that, there would have been nothing to convict him. carpet fibers would never have been enough.

I certainly agree that media should not publish every detail that help criminals or terrorist (NYTimes publishing all interception details..key senators from both parties knew those already and now Al-Qaida knows it..good work NYT). Thousands of people may die because of this (and it was probably illegal to publish those, hope NY Times editors go to jail for that)

My cellphone manual tells you that you are sending out a signal for E911. It's not exactly a secret.
Trianglulation is nothing new, even with analog signals with time they'll find you.

I wonder if Cellphone GPS has been fully implemeted in NYC?

Wonder how long until the police just ask cell phone companies for a list of every phone that was within a few hundred yards of the scene of a crime. This isn't too practical in Manhattan, but could prove rather fruitful in some parts of the country.

Nextel has a GPS system on their phones (motorola) that allows the user of that phone to track the phones whereabouts if stolen or lost. i've used it before with great success.

as for Littlejohn's phone, kudos to the NYPD. Perhaps some information that the NYPD did not release to the press is that the victim's phone and his phone were being tracked in the same triangulations, meaning, maybe they know for sure that her pings were next to his pings thus they were traveling together.

I wonder if the police got a warrant for the cell phone tracking or if TMobile just simply gives them this information when they ask...

And what the hell is up with this guy:


"It's a way to track people that is stronger than relying on witnesses," a police source said.

Yes, it's another way to gather information, but quite a stretch to imagine it's better than someone placing a criminal at a crime scene. All you can tell from the phone records was that the phone was at the scene.

Good question, jayson.
From what we've seen from all those L & O series, it appears they get them mighty quick.
Anyway, I don't have a cell phone. Just like the old days, you show up late and find me not there, not my fault. Life should be easier not more difficult.
(as shown by J. Stossel on 20/20, life is easier nowadays and people have much more free time)

I don’t use cell phones either. My tribe relies on smoke signals to contact each other from a far.

It is not as efficient or useful, but it keeps the white man off our backs.

the police do not need a warrant, they can subpoena cell records as evidence. sadly, on a civilian level, cell phone customer service reps have given out records to people claiming to be P.I.'s.

witnesses arean't always good enough for "visually" witnessing crime scenes. casse in point, a cracked out homeless women claims she saw the victim enter Littlejohns van... that testimony will never fly in a court of law, she's a drug addict, she was impaired. another homeless person, a man, claims he saw (from across the street, 30 yards away) the victim enter Littlejohns vehicle and allegedly described jewlery that she was wearing, "he was a spot on match" NYPD claimed... the police never revealed to the press what her jewlery looked like, so this could be good testimony in court.

the blood on the plastic ties is allegedly a match and will be presented at the grand jury hearing. cat hairs also allegedly from Littlejohns home were recovered on the blanket that was used to wrap the body, also good evidence... if he's not the only rapist/killer, why has he not come forward with anymore information? why? his lawyer said he will plead not guilty, so he's covering his ass.

I bet the NYPD has placed her cell phone records (pings) with his cell phone records (pings) and they match on a positioning level.

Turning off your phone won't help. You have to take the battery out of the phone to prevent your phone from syncing up with the tower. All the good criminals already know this. Trust me.

Since police can tell that Littlejohn was in the vicinity of where her body was eventually found by tracking his cellphone, why can't they track Imette's cellphone to find out where Imette have been during the 16 hours after she left the Falls?

Have the police tracked the second bouncer's cellphone?
