3-year-old girl, infant brother survive for days in home after parents' murder-suicide

A 3-year-old Southern California girl is being hailed as a hero for keeping her infant brother alive for days after her parents' murder-suicide.

"Our little angel was able to keep herself and her brother alive," Los Angeles police Capt. Maureen Ryan said. "The baby is a miracle baby, and the little girl is a hero. She's an absolute hero."

LAPD said the father, identified as 46-year-old David Kooros Parsa, killed his wife, 38-year-old Mihoko Koike. Parsa then took his own life inside the couple's Chatsworth home.

After the murder-suicide, the toddler and her 2-month-old brother were able to stay alive for "several days" and were found on Sunday. Police responded to the home after receiving reports of an assault with a deadly weapon.

Authorities said both children are healthy and in the custody of the Los Angeles County Department of Children and Family Services.
