Heathrow hotel receptionist Attila Ban has been jailed for a minimum of 26 years for the murder of two workmates.
Ban, 32, was given two life sentences at the Old Bailey after being found guilty of killing fellow receptionists Tibor Vass and Alice Adams, both 20.
His lawyer Michael Birnbaum QC said he did not know why he killed his friends and cannot remember what triggered the murders.
Both were stabbed in Ban's flat at the Heathrow hotel where they all worked in August last year.
Police were called after the receptionist wrote on Facebook "I would like to wake up from this nightmare" and all three failed to turn up for work.
He was found after he spent two days hiding under a bed where Mr Vass's body had been laid.
Ban's victims Tibor Vass and Alice Adams The Hungarian, voted employee of the year in 2010 at the Radisson Edwardian Hotel, had cut his way out of the divan and attempted to kill himself.
He was found lying on another bed in the room after the body of Mr Vass had been removed.
Richard Whittam, QC, prosecuting, said: "It became apparent that he had been hiding in the divan base of the double bed.
"He must have been there throughout the attendance of the pathologist, the removal of the bodies and the examination of the scene by crime-scene examiners."
The mothers of both victims begged Ban to tell them what happened after he was found guilty of the murders last month.
Doctors had suggested that openly gay Ban may have harboured an infatuation for Mr Vass who could have been starting a relationship with Miss Adams.
