Death By R Train: Anyone Got the Scoop?

News 12 reports that a man was hit and killed on the Bay Ridge-bound R tracks at Union Street on Monday morning.  A FIPS reader tipped us off after her commute from hell, and wants to know if anyone has any details:

I was waiting at the 9th St stop trying to get to work in Bay Ridge, got to the platform around 8:35 yesterday. And waiting. AND WAITING! At 9:50 (there's usually a train every 5 mins so it was clear something was really wrong) there was an announcement that the Bay Ridge bound R train would be running express from Pacific St to 36th St due to problems at the Union St station and there would be no fucking R train coming to pick up the very large crowd of people that had accrued until further notice. I had to get a car service to get to work and was still late grumble. My co-worker came in at 11:00am and said her R train from DeKalb was still running express from Pacific to 36th and they had told her it was a police investigation. I searched the internet hardcore today to find out what the deal was and all I could find was one measly 20 second news clip from a Long Island station that just said a man was hit and killed by the R at Union St. Anyone in the FIPS world know more info??

Know anything?  Comment, SVP.
