Thanks for the link, just a thought, but could Leah have encountered any problems/relationships (not Mr X) with customers or whomever she dealt with at the FINANCE company she worked at?
Also wondering if Leah had a "type" of guy she was attracted to, ie. older, established, artistic, athletic, white, brown black, rocker, hippy, conservative, religious, punk, ect ect?
Just because L may have had something happening with X, does not mean there is not a Y or a Z
somewhere,imo, speculation.
From link..

8am. Leah, 19, sets off for work as normal. She has an admin job with finance company DFC in Davy Avenue, Knowlhill and walks the two-mile journey to and from work every day, often going via Furzton Lake.

5.45pm. Leah walks home from work. Strangely, the location settings on her Samsung phone were switched off in the Furzton Lake area. Nobody knows why. It could be that she was downloading another app that disabled them. But the mobile phone company has confirmed Leah had never turned off her location settings before.
6pm. Leah arrives home from work. She changes into tracksuit bottoms and a long-sleeved top with the logo 'I solemnly swear that I am up to no good' (a quote from her favourite Harry Potter books) and leaves the house on foot. She tells her mum she is going to visit a friend.
7.15pm. Leah arrives home again. She doesn't fancy the meal her mum was cooking so she ordered herself a Chinese takeway. Her mum asks if her friend is okay and Leah replies with a yes.
Leah ate her meal and went to her room to watch a film. Her behaviour that night was totally normal, say her parents''
