UK UK - Claudia Lawrence, 35, Chef, York University, 18 March 2009 #18

Yup - obviously there are other masts overlapping and covering areas within the sectors (each new generation seems to require more masts for full coverage), but with no cell area data prior to 2017 this is a theoretical representation of the areas potentially covered by the antennae, based on the alignment of the triangular masthead frame. The point being that while the red area might extend as far west as Tockwith, this does not exclude Heworth, as is suggested by the Newsquest video.

Question 1 is how do the police know it stayed local till just after 10?
Q2 they can see it moved around Acomb 2 weeks prior to her disappearance - so there must me a way of measuring to nearly pin point accuracy.
Q3 where’s newsquest data from?

We should contact Mark Williams Thomas and ask him questions about the case

Cellmapper doesn't appear to have any data pre-2017, but with the various mobile providers' antennae mounted along the sides of the triangular frame the reception area (or 'view') of each of the three sides would appear to be as shown in the image below. Worth noting perhaps that if extended westward, the boundary of the northern red sector and the southern yellow sector passes pretty much exactly through Tockwith.

Well done!! - great research

Great research - could there be something we are missing which then excludes Heworth?

Aside from the above - I was wondering about hotspots - some cafes, businesses had mobile hotspots in 2009 - could Claudias phone have been connecting to something of that nature in Heworth until 10am and then disappeared off that network - similarly in Acomb?

To pick these up in turn:
1. Tbh I wasn’t aware of any suggestion the phone moved after 10am on the 19th. My understanding previously was only that it pinged the uni mast when it turned off at 12.10pm. If it were possible to ascertain the phone’s location based on calls/texts made to it, there could be other opportunities to do so overnight on the 18/19th and on the morning of the 19th.

2. Not necessarily pinpoint - my impression would be that it was localised to the area by triangulation between at least two masts (within the overlap of arcs based on signal strength/pingback time).

3. IIRC according to the video the suggestion of a 10am connection to the uni mast was made to the Times by someone inside NYP - how they came up with the specific area shown in their graphic I don’t know.

Her works manger left her a message on her phone at 10 am

I wonder why SC didn't contact her after the no show in the NH

Total fabrication by whom ? The police ? Some random prankster ? One of the naughty dozen that had it in for Claudia ( I’m being sarcastic here ) Was it a genuine sighting but not of Claudia and her abductor ?
Has the witness ever come forward?
I think it’s most probably genuine and that is why the female never came forward ( dead ) and obviously the perpetrator would stay silent !

I don't understand the logic of your saying that because the witness has never come forward she

sorry....posted in error

I think it was claimed. that it wasn't completely unknown for Claudia to fall asleep or fail to show up....I don't know if this was true or an invented excuse for. not. contacting her

 

[cortina]

I wish I could find an article I remember where the police said they believed the. whole situation started kicking off...im pretty sure that's the expression or something very similar they used...more or less as soon as Claudia had finished the phone call with her mother.

assuming they do pay attention to their language, kicking off implies some kind of loud argument at the very least....if, for example, it started just with someone calling and asking if she wanted to go for a drink, id have expected them to have been a bit more neutral with the way they put it....I must admit this goes against my gut feeling that Claudia left willingly or at least quietly...I don't think the police have ever clarified what. they meant or have even been challenged on it

Yes, but I had been going on the basis that all the info regarding calls and texts incoming to CL’s phone came from witnesses and hadn’t realised that CL’s phone connected to the uni mast at that point - though I now see this was reported in 2019.

So did it not connect to the same tower when it signed off from the network at 12.10pm? If it connected on either or both occasion, it should have been possible to establish whether the signal strength was consistent with the distance from 46 HR to the mast or not on each occasion. On the same basis the question of whether CL was at home prior to 8.25pm on the evening of the 18th should be easily resolved.

She did apparently send the “How could you stand me up” text on the evening of the 19th and then contacted PL on the morning of the 20th - I would presume she had attempted further contact with CL before doing so.

There is info in this news article showing how they tracked her phone.

Claudia Lawrence's phone was still active near home

Ms Lawrence's March 19 2009 disappearance led to a £1million murder inquiry and the latest disclosure is partly why police believe her killer was someone who knew her.

I think the reason SC didn’t contact her after the no show is straight forward, she thought her phone may of run out of charge and she was having an early night

Hi Shadwell again, good posts and I like your logical thinking. Would it be worth emailing cell mapper and asking them specifically for the information we are after ? Pj3 makes a good point - her employer calls at 10am to find out where she is and leaves a message - so phone will have connected at that point - guess it must still have been close to her home. It connects again at switch off 12.10pm - when it must have moved. Wonder if this is when it’s locations were established?

Did you pick up on this? I think it’s an error as I didn’t know she worked at the nags

“Nine people including several connected to the Nags Head pub where she worked pub have been arrested or interviewed under caution since 2013”

I think if you evaluate it in “theory” take her phone as not having left Heworth till 10am. She’s not at home. Looks like she’s left in a rush - pots in the sink, toothbrush on the kitchen drainer (but bed made) she can’t have travelled far. It must be an option to travel north south east and west from Claudia home and establish how far you have to move to connect to a different sector. Then you’d find where - then it’s just when. 6am there’s no call from her, 8.23pm on the 18th is your last text - there’s your window. She must have been put in a vehicle at some point - when? The suv parked across the pavement at 9.01pm on the 18th has to be a favourite - did it just park up in Heworth and then the following morning move. She could have been in a boot - upon disposal the perp found her phone and switched it off

Replying to myself - o dear! Could someone living in Heworth parked the car on the drive with Claudia in it, slept overnight in Heworth moved in the morning - partner none the wiser
