Minutes before he ticked off a bomb at Sri Lanka's Cinnamon Grand hotel on Easter Sunday, the suicide bomber stood in a queue for breakfast buffet, reports AFP.
The man who was responsible for the attack at the high-end hotel booked a room under the name of Mohamed Azzam Mohamed on Saturday night.
In the serial blasts, 290 people lost their lives.

Suicide bomber gave false address during check-in
The bomber, who carried a plate at the time, was Sri Lankan and checked in using a fake address. He told hotel officials he was in Colombo for business.
A manager of Cinnamon Grand Hotel said, "He came up to the top of the queue and set off the blast. One of our managers who was welcoming guests was among those killed instantly."
Buffet was serving families when bomber attacked
The hotel's Taprobane restaurant was having one of the busiest days of the year, courtesy Easter. The manager said the attack happened around 8:30 AM when the buffet was busy catering to families.
