Live Updates: Suspected Brooklyn Subway Gunman Is in Custody

The shooting left at least 23 people injured, including 10 who were hit by gunfire. Several of the victims were initially listed as critically injured, but none of the injuries were considered life-threatening. In addition to wounds from bullets, injuries resulted from falls, smoke inhalation and panic attacks.

On Wednesday, two gunshot victims remained hospitalized at Maimonides Medical Center, both in good condition, according to a spokeswoman for the hospital. Five victims were still at N.Y.U. Langone Hospital in Sunset Park in stable condition, according to a hospital spokeswoman.

The police have not yet released the names of the victims. Here’s what we know so far.

Several of the victims were children and teenagers.

During a visit to Maimonides Medical Center on Tuesday night, Gov. Kathy Hochul said that she had met an 18-year-old victim who had been on his way to school at the Borough of Manhattan Community College when the shooting took place. He was awaiting surgery from either a bullet or shrapnel wound, Ms. Hochul said.

“He seems to be doing well, and he’s in very good spirits, as well as his mother and grandmother who are there as well,” she said.

The hospital was also treating three other young people, ages 12, 13 and 16, the governor said.

She recounted a “challenging encounter” with the mother of the 16-year-old, who had undergone surgery to restore use of his thumb and was expected to be discharged on Wednesday.

“His mother does not speak English, she is Chinese, she is there alone. And it was so sad to hear her through a translator talk about her anxiety,” Ms. Hochul said, adding that the woman had just lost her job as a home health care aide.

“All she has is her son and it’s just the two of them,” she added. “So I had a long hug with her and let her know that we send the love of all New Yorkers.”

10 were hit by gunfire.

Hourari Benkada, 27, said he was sitting next to the suspect on the N train at the time of the attack. When the shooting began, Mr. Benkada told CNN, he was trying to help a pregnant woman as people rushed through the subway car trying to get away from the shooter.

As he was helping her through the car, a bullet went through the back of his knee.

As of Wednesday morning, Mr. Benkada was still at N.Y.U. Langone Hospital recovering from surgery. Doctors told him he would be able to walk using crutches in a few weeks.

“I’m in serious pain,” Mr. Benkada had said in a text message with a New York Times reporter on Tuesday night. “And I was sitting closest to the gunman — closest one to him was me.”

After he was shot, Mr. Benkada called his brother, Mehdi Mohammed Benkada.

In a text message on Wednesday, Mehdi, 32, told The New York Times he could hear screaming, shouting and an M.T.A. announcement urging riders to get back on the trains in the background of the phone call. He immediately gathered the family and rushed to his brother’s side at N.Y.U. Langone.

“It was really a sudden state of shock for us,” he said.

Mr. Benkada, speaking from his hospital bed Wednesday morning with CNN, said he may never ride the train ever again.

“All I remember is all the blood leaking out of me, to be honest,” he said.

Rudy Pérez, 20, got on the N train on his way to his construction job in Manhattan when the subway car he was sitting in suddenly began to fill with smoke. He didn’t even feel it, he said, when a bullet struck him in his left leg.

“I was scared,” Mr. Pérez told a New York Times reporter on Tuesday in Spanish. “I just wanted to get out of there. It’s all I wanted. Everyone was in a panic.”

There was one passenger he remembers in particular, he said, a young man who was shot in the hand. He looked like he had lost his fingers, Mr. Pérez said.

Mr. Pérez had to be helped off the train by another passenger. In the hospital, doctors told him he should be able to walk again in about a month. Until then, he’s not sure how he will be able to work.

“I’m afraid it’ll happen again,” he said, adding, “I’m worried about everyone else.”
