None of the victims, seven men, one woman, and a 15-year-old girl, were killed.

Until June Adan had worked as a part-time security guard on weekends at Electrolux, a home appliance shop, in the mall. He was an employee of Securitas, the security firm.

Adan wore a security guard uniform when he carried out the stabbing frenzy on Saturday night.

He was foiled by a heroic former local police chief, Jason Falconer, who happened to be shopping there.

Mr Falconer, who now runs a gun range, was praised for his "bravery and quick action" by President Barack Obama.

CCTV footage showed Adan falling and getting up three times, continuing to lunge at Mr Falconer who was shooting at him.

During the attack Adan made references to Allah and asked at least one victim if they were a Muslim.
