The third of three children who police say were attacked by their mother in Florida has died.

Palm Bay police said in a statement Monday that 5-month-old Christopher Swist was pronounced dead Sunday night.

Florida Today quotes Palm Bay Police Chief Mark Renkens as saying Monday that 33-year-old Jessica Lacey McCarty strangled the infant and 6-year-old Philip McCarty and drowned 7-year-old Laci McCarty.

At the time of the attack, police said the mother had a knife and the children had been cut. On Monday, they said there was no indication the children had been stabbed.

Jessica Lacey McCarty chose to remain in custody under a special medical watch when she appeared in court Sunday. Palm Bay police spokeswoman Yvonne Martinez said she will be charged with three counts of murder.
