A 14-year-old girl and her 4-month-old sister were found dead inside an Ontario home Tuesday, and their mother was rushed to the hospital.
Investigators said the father called police to the home on Tam O'Shanter Street around 4 p.m. When police arrived, they tried CPR on the 14-year-old daughter and 4-month-old baby girl, but it was too late. The children died.
Details about their causes of death were not immediately available.
Neighbors said the crime scene tape and police cars are simply out of place in their quiet community.
"Nothing like this has ever happened in the 20 years that I lived here," resident Priscilla Roman said.
Neighbor Danny Calderon added, "It's very sad. I wonder what the dad is going through, losing his children and his wife maybe?"
The mother was found hurt and unresponsive and was rushed to the hospital.
"It's sad, especially when you hear about it being kids. It's heartbreaking, sad because it's your neighbors," Roman said.
What led up to the tragedy and how the children died is still under investigation. The father is cooperating, investigators said.
"I just think it's sad. Hug your kids. Tell them you love them. Hold on dearly while you have them," Roman said.
The mother is now in stable condition at the hospital.
A few neighbors said they heard loud bangs that sounded like gunshots Monday night, but investigators have no reason to believe that was related to the death investigation.
Investigators said they are treating the deaths as homicides.
