Four people were shot, three of them critically, in a terrifying drive by shooting on the city's east side overnight, 1200 WOAI news reports.

  At least one gunman, and maybe more, opened fire from a passing car at a house in the 800 block of Morningview, police say.   Police say a total of 33 rounds were fired.

  Three woman and a man were hit by the gunfire.   All were rushed to San Antonio Military Medical Center, and three had wounds which were considered critical and potentially life threatening. 

 Detectives tell 1200 WOAI's Morgan Montalvo that one of the victims is a 16 year old pregnant girl.

  No immediate word on a motive for the shooting.
