Yes, possibly.
This case was one of the first cases where mobile evidence was used to identify a person's whereabouts:
In addition, this was one of the first cases in which the position of the makers and recipients of mobile phone calls was identified by the location of the cell sites through which the phones had sent or received the call. There was a great deal of factual and expert evidence on this subject at the trial.

It's extremely unlikely Steele would have forensic knowledge re the above.
Someone was calling Tate and Tucker from call boxes on the 5th Dec (bodies found on 6th Dec). Nicholls also received a call on his mobile from a call box. As I said above Tate and Tucker received calls from a call box near Stowmarket and Nicholls from Basildon. All these calls were within 30 mins and yet the geographical distance between the two is 1 hour, 12 mins/63 mins so it could not have been Steele.
Corrupt police officers from Braintree CID were no doubt aware how mobile phone data could be used to identify the approximate location of those who use mobile phones. They would certainly have an awareness of how to communicate with others to avoid detection eg use of phone boxes. An informer would simply add to all this intelligence enabling them to control and manipulate many scenarios.
There's much evidence corrupt officers were able to lure Rolfe, Tate and Tucker to Workhouse Lane on some pretext to have them slaughtered probably because they were becoming too much of a liablility and risk exposing the corrupt officers and crime bosses. If they all needed taking out it had to be done in one hit but taking out 3 wasn't something that would then be swept under the carpet so a scapegoat(s) was needed ie Steele/Whomes.
It's possible the officer(s) told Rolfe, Tate and Tucker to meet at Workhouse Lane on the basis drugs/cash were to be placed in the boot of the Range Rover and they would then ensure safe passage to a storage facility ie advise who was on patrol and which roads to take. They were told a vehicle would back up to the boot and they were not to get out so as not to leave footprints. An officer and the hitman faff around outside with the officer opening the rear driver's door and the hitman steps forward.
The Timeline5th Dec/6th Dec 1995 - It is thought Rolfe, Tate and Tucker were murdered 5th Dec around 7pm with the bodies found 6th Dec
13th May 1996 - Corry, Nicholls, Steele and Whomes arrested. Shortly after his arrest Nicholls asked to speak with DC Bird his request was refused. Bird had also been arrested.
13 th May - evening - Nicholls interviewed - no comment
14th May - afternoon - Nicholls interviewed - no comment
14th May - evening - Nicholls asked to speak with a senior officer and was seen by Det Sup Barrington. He was told Bird was in custody. Nicholls inidicated his willingness to talk about "drugs jobs" and "other more serious things would be disclosed. He asked about protection in and out of prison. He said that he would be giving information about the illegal activities of police officers.
15th May - Used car dealer and former business partner to Tate, John Marshall, is last seen alive around midday leaving a salvage yard in Pitsea, Essex. His home was Little Burstead, Essex. It was rumoured he was involved with drugs. Marshall sold a used vehicle to Kenneth Noye with false papers.
19th May - Noye murdered Stephen Cameron on the M25.
22nd May - John Marshall's body discovered in the back of his Range Rover in Sydenham, Kent. The body and vehicle were there from at least 6.30am 16th May.
It has been said Noye ordered a hit on Marshall to silence him over the car he sold him with false papers which he was driving when he murdered Stephen Cameron. This is clearly wrong since Marshall was murdered 15th/16th May and Stephen Cameron murdered 19th May.
What is interesting is that John Marshall, former business partner to Tate, was murdered only hours after Nicholls made his disclosures re "drugs jobs|" and "illegal activities of police officers".
Did Noye feel the net was closing in and/or was he at risk of being exposed and/or his life was under threat from others? I've always thought it strange that someone who was active in crime but never liked to dirty his hands per se would suddenly lose the plot in broad daylight on one of the busiest roundabouts in the world. Is this the reason he lost it with Stephen Cameron?
