The Dallas Police Department is searching for two brothers who have been missing since Sunday.
They are asking for help finding 9-year-old Joshua Portalis and his brother, 7-year-old Jacob Portalis.
Joshua Portalis is approximately 5 feet, 4 inches tall and weighs 85 pounds. Jacob Portalis is approximately 4 feet tall and weighs about 50 pounds.
The two boys are believed to be with their half-sister, 17-year-old Haley Bean. Bean reportedly took the boys from their home without permission and now they cannot be located.
Police believe Bean is traveling in a white truck with 17-year-old Chelsea McNatt.
Police said an Amber Alert has not been issued because it is not believed that the boys are in imminent danger.
Police are asking anyone with information to call 911 or the Dallas Police Department at 214-671-4268.
