Hassan Sentamu, 18, is on trial accused of of stabbing Elianne in the neck outside the Whitgift Centre in Croydon on September 27, 2023.
The defendant, who declined to give evidence, has claimed his autism spectrum disorder caused him to lose control during the meeting to exchange belongings with his ex-girlfriend, who was Elianne’s friend.
The prosecution says he flew into a rage and had no lawful excuse for having a kitchen knife, having picked it up at home after an earlier incident of perceived disrespect.
At 2.43pm on Tuesday, Mrs Justice Cheema-Grubb sent the jury out to begin deliberating on verdicts.
The jury was later sent home and told to return in the morning to resume deliberations.
Sentamu, of New Addington, near Croydon, has admitted manslaughter but denies murder and having an article with a blade or point in public.
