Dallas police say a man has been slain and two women wounded by a gunman who fled after the shootings near a lake.
Police on Monday searched for the suspect and tried to determine what sparked the attack.
Investigators say the shootings happened Sunday night in a parking lot along Bachman Lake.
Authorities say some men and women were talking when another man drove up, apparently began upset and opened fire before fleeing.
Police did not immediately release the name of the man who was killed. Authorities say the women suffered gunshot wounds that are not believed to be life-threatening.
