DALLAS -- Dallas police issued a critical missing alert Tuesday night for two children who have been missing since Sunday.
Investigators say Joshua Portalis, 9, and his seven-year-old brother Jacob were removed from their home in the 19000 block of Dallas Parkway by their 17-year-old half-sister Haley Bean.
Police said the three may be traveling in a white truck.

No Amber Alert has been issued because police say they don't believe the boys are in danger.
