Seems like she was a very interesting girl, suicide by train seems so harsh.
From an article interviewing her cousin (http://www.boston.com/sports/baseball/redsox/articles/2008/03/13/in_terms_of_popularity_casey_runs_unopposed?mode=P F)
But while Casey waited outside the clubhouse, there was no Uncle John. He checked his cellphone and realized his wife, Mandi, had tried to call him numerous times. He called her back. "Are you sitting down?" she said. "Emma committed suicide."
Emma was Casey's youngest cousin, a 15-year-old who that day had sat down in the path of an oncoming subway train, her back turned to the onrushing lights. Uncle John, Emma's father, had received that news in a call from his son on his way into the ballpark.
"That was one of the toughest nights of my life," Casey said. "One of my worst moments ever, and it was at Fenway Park. The next day I told [manager Dave] Miley that I didn't think I could play in the field because my mind was a wreck. I DH'd; that game was like a fog. Everybody loved Emma. She'd just come down to visit us that spring in our house in Jupiter [Fla.]."
