Former NFL Player Aaron Hernandez Found Dead Inside Prison Cell
Former NFL star Aaron Hernandez was found dead in his prison cell April 18, only days after his acquittal in a double homicide. He says Hernandez would have been transferred to a mental health unit if there was any concern about his well-being.
Fans crowded the brief ceremony, hugging and posing afterward for pictures with Switzer, a women's running pioneer.
Running the 1967 Boston Marathon changed the course of Switzer's life. Having registered under the name KV Switzer, her gender went unnoticed by officials at the start line, but a few miles in she was attacked by an angry official who tried to pull her off the course - creating an enduring image of women's right's history.
Pictures of that splashed across newspaper front pages, and Switzer somewhat inadvertently became a symbol of the women's movement.
Switzer went on to win the New York City Marathon in 1974 and successfully campaign for the women's marathon to become an Olympic sport in 1984.

"Fifty years before, it was so freezing", she said. I don't make the rules, but I try to carry them out. It was extremely validating. But anytime I doubted myself, the crowd wouldn't let me stop.
"I expected victory since I had trained well for this race", said Kirui, who drew motivation from Kenyans who had won the race before like Korir, Geoffrey Mutai and Robert Cheruiyot.

Clinton apologized solemnly during the call, saying she was sorry to have let him and the party down. In the ad, Sanders would tout Clinton for her education, healthcare and minimum wage proposals.
Kathrine is just one of a handful of courageous women who entered races when it was forbidden, but what makes her so special is what she's done with her notoriety.
