Two brothers, ages 9 and 11, have died five days after a pool accident at a suburban Dallas apartment complex that also left their 10-year-old sister dead.
A statement from the Irving Police Department says 9-year-old Treshawn Smith and 11-year-old Anthony Smith died Sunday night after five days on life support at Children's Medical Center of Dallas.
The 10-year-old sister August Smith died hours after the Wednesday afternoon incident.
Irving police say the children's mother summoned help Wednesday afternoon when she noticed her daughter and her sons under water at their apartment complex. Police say the mother, who can't swim, was at the shallow end of the pool with two younger children, ages 3 and 6, when she realized she no longer heard the older children.
