DARIEN - Metro-North says toxicology tests on the Darien man hit and killed by a train earlier this year came back negative.

Kevin Murphy, 55, was waiting for a train at the Noroton Heights station when he disappeared from view last March.

Authorities say he was hit by the train and died from blunt force trauma.

They are not treating his death as a criminal investigation, but are still trying to determine how Murphy wound up on the tracks
