A man has been jailed for life for the murder of a man and woman in west London.
Receptionist Attila Ban, 32, hid in a bed base after stabbing two colleagues to death at a hotel in Heathrow last year.
Ronke Phillips sent this report from the Old Bailey:
Rozalia Vass, the mother of Tibor Vass, has also made a statement following the sentencing of her son's killer.
The following is a series of extracts:
"On the 11th August I got to know that two innocent 20-year olds, my son Tibor and his friend Alice, were murdered. I got to know that their lives were taken away by Tibor's friend. It was impossible and devastating to believe something like this could happen.
"Previous to that, it was comforting for me to know that Tibor found a good friend in London who was mature, friendly and intelligent.
"His friend promised me personally to look after my son and not let anything happen to him. I trusted him and regarded him as one of my own. That is another reason why the news about my son's murder was so devastating.
"I cannot describe the feeling I have in losing my son in such a tragic way. There are no words to describe the agony and the loss we as a family live with for the rest of our lives."
Sarah Adams, the mother Alice Adams, has made a statement following the sentencing of Atilla Ban.
The 32-year-old hotel worker has been handed two life terms for murdering Alice and another of his colleagues at the Radisson Edwardian Hotel at Heathrow Airport.
The following are extracts from Mrs Adams's statement:
"My heart is broken. My life will always be tinged with sadness. I miss Alice so much. I would do anything for one more Alice squeezy hug, one more smile…
"Every single person I love and care about is carrying the burden of incredible grief. My daughter Caroline is 19, just a year younger than Alice.....Alice's murder has changed her view of human nature and she says she doesn't want to live in a world where things like this can happen.
"She has nightmares every night, panic attacks and is scared of people she doesn't know. She has a constant nagging fear that someone else she loves is going to die. She has lost her best friend."
"Alice loved and cared for everyone she ever met, friends and strangers alike. It breaks my heart to know that the last thing she knew was hatred and violence.
"Alice's death has created extreme emotions, grief, anger and overwhelming sorrow within my family and have changed our family forever. As a mum, you are supposed to protect your children, and every day and every night I have to deal with the knowledge that I failed."
