Nick Figueroa stood outside an American Red Cross center Thursday with worry on his face, hoping his oldest son survived the lower Manhattan blast.
Family members said Nicholas Figueroa, 23, was on a blind date at Sushi Park, the restaurant in the building that collapsed after a suspected gas leak set four buildings ablaze.
His date suffered a broken nose and was at Bellevue Hospital Center on Thursday, the family said. She is among 19 people injured, four critically, in the explosion.
"She can only remember the time of paying and time of waking up in the hospital," said Figueroa's brother Neal, 22.
His father said: "So where is my son?"
The mother of Figueroa's date called his mother, family members said. Family members said they repeatedly called Figueroa's phone.
"I went everywhere, every hospital. We've contacted so many people and nothing," Neal said.
They said they also have contacted police who planned to visit hospitals with Figueroa's photo.
"I just hope everything is OK because I'm going to go crazy," said Nick Figueroa, 52.
The family learned about Figueroa's blind date with a co-worker at Bowlmor at Chelsea Piers from a mutual friend. Family members also looked at Figueroa's bank transactions, which showed a pending charge for $13.04 at Sushi Park.
Family members said Figueroa lives with his family on the Upper East Side and is a recent college graduate.
"I'm praying for the best," Neal said.
