SUNRISE, Fla. -

A 1-year-old boy and his twin sister remain in critical condition after they were found floating in an apartment complex community pool Thursday in Sunrise.

"At this time the children are still alive, in critical condition, at Plantation General Hospital," Sunrise police Officer Michelle Eddy said a statement Friday morning.

The children, almost 2 years old, were identified as Jada and Henry Roman. Their mother, Althea Bradford, is the property manager for the complex.

According to police, the children were under the care of a resident at the complex.

"There's two dead children in the pool," Bradford can be heard screaming in a 911 call released Friday.

Bradford was not aware the children were her own at the time of the call.

Police said that the investigation is ongoing and no further information is being released.
