AUS - Khandalyce Kiara Pearce (Wynarka) and mum Karlie Pearce-Stevenson (Belanglo) #8

I think we should note that we are talking about phone pings and not GPS tracking.
GPS tracking is obviously very accurate, but pings rely on triangulation from towers and only indicate an approximate area.

I know, but if Karlie's phone would have been in Canberra while DH was pinged in Belanglo forest that could be quite remarkable.

 

[DutchTreat]

Does anyone know if the explorational drilling was for oil or for minerals?

 

[JaneSA]

I'm also wondering about Karlie's phone. Was it pinged in Belanglo too?
Or was it in another location when DH was pinged in Belanglo Forest. Cause that could be an indication that she either didn't die in Belanglo Forest, that it could have been planned etc.

Interesting - a ping only tells you where the PHONE is (approximately).
How do you prove the person was with the phone?

Department of Human Services (Centrelink included), have very much tightened up identity requirements since July 1 this year. I have very recently been 'thru the mill', spending hours on the telephone and attending twice in person (2 1/2 hours each time) trying to identify a relative for whom I am the administrator. . Unbelievable! This person has never held a driver's licence, passport or any form of photo id. Medicare card is no longer acceptable as part of id as DHS issue this card themselves. Full birth certificate is also not enough on its own. All this person held was a Disability Support pension card and a Medicare card. Not good enough. However, after all those hours, on my last attendance, the staff member was informed by another area that no other id was required, as all I was trying to do was to change the relative from DSP to Age pension due to their age now qualifying them for Age pension. The relative had been a client since 1982 on DSP. There was no change in pension rate involved. I could not believe what I had to go through though.
If the rules had been this stringent in 2008 to 2012, a certain person may not have got away with fraudulent attendance at Centrelink office in SA.

BBM.

Definitely, that's why I included the complete series because I have little doubt that Karlie's photo ID wasn't used in the frauds.

My guess would be that they obtained the phone records from Telco's when Karlie's remains were found.

The request was probably for phone tower records as far back as the Telco's had, which would have been less than 2 years in 2010 not the 7 that everyone is thinking.

Until Karlie was ID'd they were unable to connect any of those pings.

 

[inkpink]

Do they first need a phone number to see where it has pinged or can they see what phone numbers are pinging in a certain area at given times?

[h=2]Locating the baddies[/h] The data exchanged as part of this process can be of great use to law enforcement agencies since it can provide information as to the approximate location at certain times of the owner of the mobile phone.
At the very least it can tell an investigator which cell the mobile device (and hence the owner of the device) was located in at a particular time. But if the investigator is prepared to analyse the data, much more accurate location information can be obtained.
To manage handover between cells, the base station monitors the signal strength from the handset. This can give an approximate measure of the distance from the base station.
Also, since most base stations use directional antennae, the base station can give a good estimate as to the location of the mobile device. Multiple base stations may be monitoring the signal strength, making it possible for an investigator to pinpoint the location of the mobile phone to a particular house.
It is worth pointing out this method of estimating location is quite distinct from GPS used for location aware apps in smart phones. Apps in smart phones may include GPS data (such as location services in mapping applications or geotagging in images) but accessing it by law enforcement agencies is not straightforward.
In contrast, determining location using tower data is much simpler since the method relies only on monitoring who is connected to the base station and what their signal strength is.

Would it be possible to establish if DH could have been with other people on the 14-15th? To see if he can be paired with other phones on the 14th and 15th. Like he has been with other phones pinged at the same locations, except for Belanglo State Forest because the other person(s) were smart enough to switch their phone off.

Mobile phone forensics (Wikipedia):

'Mobile device forensics can be particularly challenging on a number of levels:[3]

Evidential and technical challenges exist. for example, cell site analysis following from the use of a mobile phone usage coverage, is not an exact science. Consequently, whilst it is possible to determine roughly the cell site zone from which a call was made or received, it is not yet possible to say with any degree of certainty, that a mobile phone call emanated from a specific location e.g. a residential address.

• To remain competitive, original equipment manufacturers frequently change mobile phone form factors, operating system file structures, data storage, services, peripherals, and even pin connectors and cables. As a result, forensic examiners must use a different forensic process compared to computer forensics.

• Storage capacity continues to grow thanks to demand for more powerful "mini computer" type devices.[4]

• Not only the types of data but also the way mobile devices are used constantly evolve.

• Hibernation behaviour in which processes are suspended when the device is powered off or idle but at the same time, remaining active.'

Anecdotally, years ago, one well-known method to simply anonymise your mobile phone/movements was to take your SIM card out of your mobile phone and turn it off.

Fairfax Media has confirmed Australian law-enforcement agencies are using a technique known as a "tower dump", which gives police data about the identity, activity and location of any phone that connects to targeted cell towers over a set span of time, generally an hour or two.
A typical dump covers multiple towers, and mobile providers, and can net information about thousands of mobile phones.

I am curious too about medicare fraud. Doctor shopping and all that. health card cheap drugs etc.

 

[inkpink]

Deleted - Nothing to do with anything....

Do you mean in this case, plongi, or more generally?

Generally, If someone was either accessing medical services, or self-medicating with drugs obtained by them through a prescription from a medical practitioner; using someone else's Medicare card, I think it would lead to, at the very least, fraud charges. It could also be a nice little earner if that person was on-selling prescription drugs or restricted over-the-counter medicines; especially the particular drugs which are used as 'precursors' to illegal ones.

I'm not sure about the relevance in this particular case though. If so, talk about 'taking someone for all they're worth'. Disgusting.

Reminds me of our Fig Tree Pocket sleuthing, and when the phone was connected to the charger and removed :moo:

I think it is about a reasonable assumption that a person is with their phone …. especially if there is other corroborating data such as sightings/ petrol receipts/ CCTV footage/witness statements that match the signal data and lead to that same assumption.
