The Bedford Police Department earlier confirmed they were investigating a possible unattended death at an address owned by Robert F. Kennedy Jr. Authorities found a deceased individual inside "an out building" on the property, police said in a statement. Regarding her marital status at the time of her death, Mary Kennedy wasn't divorced from Robert F. Kennedy Jr., her family attorney, Kerry A. Lawrence, told CNN. Details of the couple's private lives were exposed after Robert F. Kennedy Jr. filed for divorce in Westchester County on May 12, 2010. The next evening, according to police records, Bedford police responded to a 911 call. When police arrived at the Kennedy residence they found the couple in an argument over taking their four children to a carnival at St. Patrick's School. According to a "domestic incident" report filed by the officer on the scene, "Mr. Kennedy stated that his wife was intoxicated and was acting irrational so he took the children to the carnival to remove them from the situation." No one was injured, the report said. Two days later, Mary Kennedy was arrested for driving while intoxicated. At the time, Bedford Police Lt. Jeff Dickans told CNN that Mary Kennedy was arrested around 9:15 p.m. on May 15, 2010. Dickans said that a Bedford police officer saw Kennedy's 2004 Volvo swerving onto the curb of Greenwich Road in Bedford and asked her to pull over. Kennedy had slurred speech, and a blood-alcohol content above 0.08 percent, the legal limit in New York. She was charged with driving while intoxicated.
