QUEENS, N.Y. (CBS 2) — Kristian Paiva recounted his brother’s final moments Saturday as police were gathering evidence in Queens , hoping it will lead to an arrest in a fatal subway stabbing that killed 27-year-old Dario Paiva.

“Somebody’s life was just lost for no reason,” Kristian Paiva told CBS 2’s Jay Dow. “I’m never going to see my brother again.”

Paiva said the deadly encounter occurred around 11:30 p.m. Friday, when four young men surrounded him on his way home from the video store near the 85th Street station.

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

Paiva said when his brother arrived, the young men ran, but they then followed the group upstairs to the station stairs in order to give police the suspect’s description. But they were waiting.

“Then everybody pulled out knives,” Paiva said. “The one skinny one put on Latin King beads. They came running up to us. And Dario told me to run.”

Paiva accounted his brother’s final moments with tears in his eyes.

“He pushed me out of the way, and they stabbed him right in the heart.”

Dario Paiva, 27, was later prounounced dead at Jamaica Hospital.

Residents told CBS 2HD they noticed a decline in the neighborhood, which they attribute to kids walking around with weapons, harrassing innocent strangers, and the perceived scarcity of police at night.

“It doesn’t seem like it’s very good. There’s been some issues around the neighborhood lately too, around here,” said resident Glenn Innace. “There’s been some robberies, some hold ups.”

Police are still investigating what sparked the fatal confrontation.
