Russell Square 'knifeman', 19, was 'quiet, shy pupil who was bullied at his London school' as victim is named as Florida professor's wife who was due to fly home TODAY

Retired teacher Darlene Horton, 64 (centre), was due to return to America with her professor husband today but died after being brutally stabbed by a crazed knifeman in Russell Square last night. 


The keen tennis player has spent the last few weeks in the UK with her husband, psychology lecturer Richard Wagner, as part of a summer study programme and was due to return to the US today. However, she died in the mass stabbing at about 10.30pm in Russell Square last night when the Somali-born attacker walked up to his unsuspecting victims and slashed them with a kitchen knife. Ms Horton's last words were 'he's still here' as she tried to warn others of the attacker. Witnesses said her shocked husband sobbed nearby as her body lay sprawled on the pavement overnight (bottom right). Tonight, it emerged that the man accused of stabbing Ms Horton to death and injuring five others was a 'quiet, shy pupil who was bullied at his London secondary school'. Zakaria Bulhan, 19, moved to the UK from Norway in 2002, and was said to be suffering possible 'mental health issues'. As well as killing Ms Horton, the knifeman also injured Israeli holidaymaker Yovel Levkowki, 18 (left and inset), who was slashed across the hand as she approached him to offer help after believing he was a victim. She said today she was 'lucky to be alive'.
