I talked to a cop who was part of the investaigation last night. He said basically it was over a bad $10 or $20 weed transaction (which is brutal). BAsically the guy ripped her off and so she started harrassing him, but he ended up pushing her off the platform during the scuffle (this was way before a train was approaching.). The he got up and kind of left (started heading down the platform), then just as a train came in, this girl shoved him right into it. So even though he knew the girl was still kind of after him, it sounds like he may not have seen the fatal push coming.
Basically, his body hit the first car and started kind of rolling along it (witnesses said they heard something that sounded like gunshots, the cop then told me this was the sounds of his bones breaking
.) He then fell between the first car and the second car, and 'corkscewed' between the cars. It sounded like a mess, but he said there was actually no blood, as his body hadn't 'split open' anywhere.
On a side note, he said it was discusting how many people were trying to see under the train. That's supposed to be the worst part of his job, and here these people are, doing everything they can to get a glimpse.
