PI Uses Metro Card as Witness

When Jason Jones was arrested in a fatal shooting in the Bronx in May, he told the police that he had been nowhere near the scene. He said he had left work, ridden the bus with some co-workers and cashed his paycheck, and later had taken a subway to see his girlfriend.

Federal prosecutors charged Mr. Jones and his older brother, Corey, in the shooting, saying they had killed the victim because he had been a government witness in drug and gun cases. Both men could face the death penalty if the government decides to seek it.

But in recent weeks, the case has taken an extraordinary turn — because of Jason Jones’s MetroCard.
