Overview
- The guilty verdict, returned Tuesday 10 November after a nine-day trial at Harrow Crown Court, found Leon Douglas guilty of murdering 40-year-old Khalid Marchoud.
- Police say Marchoud was found with a fatal stab wound outside a ninth-floor flat in Tollgate Gardens after an altercation on 19 December and later died in hospital.
- Court testimony described Douglas arriving to visit a former housemate, arming himself with a kitchen knife, confronting Marchoud and then following him out of the flat before the fatal stabbing.
- Detectives used CCTV, mobile-phone enquiries and witness accounts to piece together Douglas’s movements; he tried to evade capture by discarding clothes, shaving and dyeing his hair and was traced to Cricklewood and arrested on 23 December after attempting to flee through a ground-floor window.
- Sentencing is pending and police said the case shows how digital forensics and witness cooperation can be used to reconstruct violent incidents and secure convictions, a step that may influence how similar investigations are pursued.
