The gunman who killed 50 people at an Orlando, Florida, nightclub in the deadliest mass shooting in U.S. modern history was emotionally and mentally disturbed with a violent temper, yet aspired to be a police officer, his ex-wife said on Sunday. Sitora Yusufiy, the former spouse of Omar Mateen, 29, identified as the shooter slain by police at the end of Sunday's massacre, also told reporters in a news conference aired on CNN that she was "rescued" by family members from her ex-husband after four months of a stormy marriage that ended in divorce. http://english.ahram.org.eg/News/222882.aspx
