A man abandoned by his brother after their speeding car crashed in Queens has died of his injuries, police said Wednesday.

Their mother “is distraught — one son passed away, and the other is accused of leaving him alone,’’ said Steven Scordio, who owns the construction company where victim Angel Camacho, 21, worked.

“She is hysterical. She can’t talk to anybody,’’ Scordio told The Post.

Camacho and his little brother, Aiden Camacho, 19, lived together in Queens.

“[Angel] took his brother under his wings . . . They were best friends. I asked Angel, ‘What does your brother look like,’ and he said, ‘He looks like me without the beard.’ He said it with pride,” Scordio said.

Angel was riding shotgun in a 2008 Acura sedan driven by his brother when the car suddenly spun out of control and slammed into a parked vehicle in Woodhaven around 4:15 a.m. Sunday, police said.

The car then careened off the parked vehicle and into a tree before it finally crashed through a fence near 85th Street. The wreck happened about a mile from the home where the two men grew up, neighbors said.

The younger brother took off on foot, leaving his older sibling critically injured inside the car suffering from severe head trauma and internal injuries, officials said.

Angel Camacho was taken to Jamaica Hospital and died Monday. Aiden Camacho jumped into a passing car when a good Samaritan stopped to help, cops said. “He left his brother,” a police source said of Aiden. “Effectively left him for dead.”

Aiden was dropped off at Interfaith Hospital but also fled from there, according to police. Police were able to get a photograph of him leaving the hospital and are searching for him, cops said.

But Scordio said he doesn’t believe that Aiden would abandon his beloved sibling.

“He would have never left his brother behind,’’ Scordio said. “Aiden looked up to Angel. He’d go to him for advice, guidance. They looked out for each other.”

He said the family believes that Aiden “was pulled from the car by a pedestrian.’’
