Two siblings saved their baby sister’s life after their own mother tried to strangle her, Florida police claim.

Ailenys Carmenate’s 12-year-old son and nine-year-old daughter attacked her in a desperate attempt to stop her choking her own six-month-old baby to death, according to a harrowing arrest report.

The mother had locked her three children in a bedroom before trying to kill her youngest “by pressing her elbow against the victim’s throat,” police said.

The brother and sister bit her arms, kicked her and pulled her hair as they tried to save the infant’s life; the 12-year-old broke free to unlock the door to allow Randy Montano — the baby’s father and the older children’s stepfather — to rush in to try and stop her, having heard the cries for help, official records show.

As he tried to pry Carmenate’s hands from their daughter’s throat, they fell to the floor, causing the baby to suffer a head injury, the report states.

Montano fled the apartment with the baby, after which the other children told police she then tried to strangle her son; he managed to wrest himself free and escape too. FULL STORY HERE
