The mother of three children who were found dead at their West Hills home over the weekend has been charged with their murders, according to the Los Angeles County District Attorney’s Office.

Angela Flores, 38, has been charged with three counts of murder for the deaths of her three children who were identified Tuesday afternoon by the Los Angeles County coroner.

Flores is accused of killing her daughter, 12-year-old Natalie Flores, and her two sons, 10-year-old Kevin Yanez and 8-year-old Nathan Yanez.

Police had originally said two of the boys were 8 years old.

Angela Flores was arrested Sunday after the children were found dead inside their home. She admitted to investigators that she killed her kids and was helped by a teenager, the Los Angeles Police Department said Monday.

The unidentified 16-year-old was also detained in connection with the investigation, the LAPD said.

Police were called to the home in the 22500 block of Victory Boulevard around 7:40 a.m. Sunday and found the three children unresponsive. The kids were declared dead at the scene.

No information about the cause of death for the children has been released.

Neighbors said they heard a woman screaming Saturday night while holding a candle and a bible.

“I figured she was just in the wrong place … mentally not OK, but it ends up being she lived two houses down from us,” neighbor Pricila Canales said.

Another neighbor said there was no reason to suspect anything was wrong at the home prior to the incident.

“They have the nicest house on the block. They looked like really nice people. No reason to suspect anything,” he said.

Flores is being held on $6 million bail and is scheduled to be arraigned on Wednesday.

Meanwhile the 16-year-old was arrested on suspicion of one count of murder and is being held without bail at Sylmar Juvenile Hall, according to LAPD.

District Attorney George Gascón said Tuesday evening that prosecutors were “working to hold accountable those responsible” for the deaths of the three children.

“We all grieve for these children. The loss of their young lives is a tragedy that has affected our entire community,” Gascón said.
