A community continues to mourn after the deaths of 5-year-old twins in the Bronx.

“I couldn’t believe it. I was in shock. I could not imagine feeling that,” said a neighbor, Yuni Fermin.

A makeshift memorial stands outside the building on East 175th Street where the boy and girl lived and were found dead Monday. Two bouquets of flowers are on either side — one tied with a pink bow, the other with a blue bow.

“As a mother, when I heard about that, I just wanted to cry, because I have two kids of my own and I cannot imagine going through that. That must be hell,” Fermin said.

Residents in Mount Hope came out to pay their respects to the family Wednesday, lighting candles and joining together in prayer.

Sources told NY1 the brother had been sick for over a week with cold-like symptoms, while the sister had an ear infection and was vomiting. They said the mother last saw the twins alive at 5 a.m. Monday morning. She thought they were sleeping, but when she went to check on them around 11 a.m. they were foaming at the mouth.

“I was very sad, because I don’t know what happened,” said another neighbor, Nadina Tutubaa.

Sources said the mother called 911 and tried to perform CPR, but could not save them. Police said Monday they did not expect any foul play was involved in the twins’ deaths.

“I wish they knew what happened. I think that will help them recover or be happier somehow, but it’s not easy. For you to lose a baby, not even a baby, but babies. It’s too much,” Tutubaa said.

Sources said no drugs were found in the apartment, and there was no indication of carbon monoxide poisoning. The medical examiner will determine the cause of death.
