Ex-wife says Orlando gunman was 'one insane person'; Mayor 'uplifted' by community reaction

Orlando mayor Buddy Dyer has said he is uplifted by the way the community has come together during a city-wide prayer service for the 49 people who were killed in a nightclub shooting.

More than 1,000 people - including many clergy and local, state and national civic leaders - met at First Baptist Orlando to hold a vigil for the victims of the Sunday morning shooting at the Pulse nightclub.
