An Oklahoma woman has been charged with child abuse after she allegedly tried to drown her daughter and a nephew at a public pool earlier this summer.

Court documents say that a lifeguard found the children unresponsive at Will Rogers Aquatic Center. They were revived and taken to a local hospital, but police noted that 34-year-old Flor Ontiveros appeared unconcerned with officers arrived on the scene, KOKH reported.

The documents say Ontiveros held her 6-year-old nephew’s “entire body and head underneath the water and multiple people were yelling at her.” They further say that the 4-year-old girl told investigators that her mother “pushed her face underwater” and “that her eyes were open and she was breathing water.”

Both children were unresponsive when they were taken out of the pool. The lifeguard administered CPR.

Ontiveros was reportedly “smiling and speaking calmly about the incident to police” and that witnesses said she was smiling while holding the children under water.

When she was interviewed about the incident several months later, the documents say, she was “adamant” she didn’t try to drown the children, although she said it was something she could have done.

She has been charged with two counts of child abuse and is being held on a $250,000 bond.
