Two toddlers who nearly drowned were hospitalized Friday afternoon after being found in their grandmother's swimming pool in Richardson.

The grandmother brought the girls home from mosque services and began cleaning up the house, said Richardson police spokesman Kevin Perlich.

She did not know that the girls had gone into the backyard pool area until two of their uncles came in the back gate and saw them at 2:50 p.m. They performed CPR until paramedics arrived.

One girl was transported to Children's Medical Center Dallas. The other was taken to Medical City Hospital in Dallas.

At the hospital, the girls had a pulse but were breathing with ventilators, Sgt. Perlich said.
