UPDATED to reflect that the indecent involved a pedestrian, not a motor vehicle as I first thought.
The 9:30pm outbound Kingston commuter rail struck a man near the Essex Street crossing in Whitman Thursday night; the first emergency call was received at 10:06 pm, according to chatter heard on a police scanner. I cannot confirm whether or not that this incident was fatal.
Curiously, I can't find one mention of this in local media - not even the local South Shore papers. I guess T accidents after daylight hours don't give good enough photo ops to make the news.
