A Glendale woman who couldn't swim jumped into a pool to save her 5-year-old son, who she mistakenly thought was drowning Sunday night.

The 37-year-old mother and son were at a home about 7 p.m. near Glendale and 71st avenues when the incident occurred.

"Her son was in the pool splashing so much she thought he was in trouble and she jumped in to help save him," said Eddie Smith, a spokesman for the Glendale Fire Department.

When the boy saw that his mother was drowning, he ran to a neighbor's house for help. The neighbors dialed 911 and pulled the woman from the pool. They performed CPR until officials arrived.

The woman, whose name was not released, had no pulse and was not breathing when medical crews arrived at the house.

She was taken by helicopter to St. Joseph's Hospital and rescuers were able to get a pulse on the way there, said Smith.

Fire officials did not have an update on the woman's condition at the hospital.
