NEW YORK (CBS 2) — Police made an arrest in the case of a Queens man who was stabbed to death while trying to help his younger brother.

Dario Paiva,27, of Woodhaven died Friday night on the Forest Parkway J train platform. He was home when he got a frantic phone call from his younger brother, Khristian Paiva, who said he needed help fending off four attackers outside a video store on Jamaica Ave. near the subway station.

“One pulled me to the side and tried to pull a knife on me,” said Paiva. “That’s when my brother showed up.”

Benjamin Moreira, 19, of Elmhurst was charged with murder and weapons possession.

Police said a description from a witness helped them track Moreira down.

When Dario arrived to help his younger brother, the suspects ran up the stairs, and the two brothers followed them so they could get a description to give to police.

But the suspects’ knives came out, and Dario performed a heroic act. Unfortunately, it would bet he last act of his life.

“Dario told me to run,” Khristian said. “He pushed me out of the way and they stabbed him right in the heart.”

Dario had a long-term girlfriend, no kids, and recently left a job in banking. “We just want Dario’s memory to stay alive,” said Santiago. “And not to happen again to anyone else.”

“He had a good heart,” said Gloria Santiago, the victim’s cousin. “He was family oriented. He didn’t deserve this.”
