Two teens killed in a train accident outside Baltimore Monday had been tweeting messages and photos from the rail bridge minutes before the train derailed.
Elizabeth Nass and Rose Mayr, both 19 and both from Ellicott City, Md., died when a CSX training haul coal derailed and fell from the bridge in their hometown.
At 11:40 p.m. ET, Elizabeth Nass tweets, "Drinking on top of the Ellicott City sign with @rose_petals," a reference to her friend, Rose Mayr.
Shortly afterward, Rose tweets a photo of the town from the bridge, with the caption, "Looking down on old ec," a reference to Ellicott City.
Then, at 11:51, Rose tweets a final photo, this one showing the girls' feet dangling from the bridge. It has a one word caption: "Levitating."
