Victims of Sri Lanka Easter Sunday attacks

Nicholson, his wife Anita, 42, and their two children Alex, 11, and Annabel, were on vacation in Colombo when the attacks happened.

The family was having breakfast at the Shangri-La Hotel on Sunday morning when two suicide bombers came into the restaurant.

The blast left Nicholson injured as well, but when the shell-shocked father came to, his only thought was for his family.

Pushpa Zoysa, who is in charge of emergency triage at the National Hospital in Colombo, told MailOnline that the father came into the hospital "covered in blood," searching for his family.

"He spoke to me twice, asking about his family. He had blood all over him but he was not injured, apart from a small cut to his ear. He was not running or crying, he was shocked. We wondered whether he was confused but he seemed in control. He just kept asking about his family members.

"He was walking around completely alone and I feel sorry for him but there were so many dead and dying people here, I didn't have time to speak to him more. Eventually he left," Zoysa said.

The Times reports that Nicholson eventually found his son's body at the mortuary. His wife and daughter have since been confirmed dead as well.

According to their LinkedIn profiles, the Nicholsons worked as lawyers in Singapore.
