A Brooklyn judge has thrown out a murder conviction for a man accused of taking part in the 1991 shooting of two corrections officers, citing the “false and misleading practices” of a retired New York City police detective tied to numerous vacated convictions.

“Evidence of guilt, other than the unreliable testimony of a sole witness, does not exist in this case,” Acting Brooklyn Supreme Court Justice ShawnDya Simpson said in court Tuesday, ordering a new trial for John Bunn.
