Celebrity chef Anthony Bourdain hanged himself in French hotel bathroom with bathrobe belt, French prosecutor Christian de Rocquigny tells the AP. Rocquigny, the prosecutor of Colmar in France's eastern Alsace region, also says there did not appear to be much planning in Bourdain's suicide, the AP reports. "There is no element that makes us suspect that someone came into the room at any moment," he says, adding that a medical expert had concluded that there were no signs of violence on Bourdain's body. Rocquigny says toxicology tests were being carried on Bourdain's body, including urine tests, to see if the 61-year-old American took any medications or other drugs, in an effort to help his family understand if anything led him to kill himself. (Bourdain's friends are mourning the loss.)
