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 near their parents' bodies. 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.
