Death at 86th St. R train station???

Did anyone hear what happened Tuesday night at the 86th St. stop on the R line? I was on the R and the conductor announced we'd be skipping 86th St. due to a "police investigation." As we pulled through that station, everyone on the train gasped when they saw a body bag on the platform, about 10 cops, and an MTA worker cleaning the tracks. Even today, there is sand all over the tracks right next to where the body was lying. Anyone hear anything? A jumper? Pushed onto tracks?
