Police believe a couple found dead in a suspected chemical suicide pact met only hours before after making contact on the internet.
Stephen Lumb, 35, from Sowerby Bridge, West Yorkshire, and Joanne Lee, 34, from Great Notley, near Braintree, Essex, were found in a car parked near an industrial estate on Monday.
It is understood the pair made contact on an internet suicide forum.
Truck driver Mr Lumb then drove 200 miles to Braintree to meet Ms Lee.
The Sun reported that Ms Lee wrote on the forum on September 4 that she was "desperate" and wanted to "do it ASAP".
She wrote: "I haven't the strength to do this alone. I'm not a cop, a cannibal or a murderer, just desperate. I have all the ingredients and want to do it ASAP."
The bodies were found in the fume-filled car, which had notes placed on the windows warning of the toxic chemicals inside.
The Sun said Ms Lee, who reportedly had a severe eating disorder, had used the forum to ask advice on concocting a toxic mix to take her own life.
A source close to the investigation said: "We believe they met a few hours before this tragedy."
