Police say a gunman killed two people and wounded four others, including three police officers, before taking his own life at a house in a Dallas-Fort Worth suburb. Haltom City Police Sgt. Rick Alexander identified the gunman Sunday as 28-year-old Edward Freyman. Also dead are 33-year-old Collin Davis and 32-year-old Amber Tsai. Phillips said the three were known to one another, but their relationship was unclear. Police say officers were sent to the residential neighborhood to answer a domestic disturbance call. Security video showed officers approaching the house from which the call came when gunfire erupted, wounding three officers.
