The mother of a 10-year-old boy who died after being found unresponsive in the family's home in Lancaster was arrested Friday, and both she and her boyfriend have been charged in the homicide, authorities announced.
Heather Maxine Barron, 28, has been charged with one count each of murder, torture and child abuse, according to the Los Angeles County District Attorney's Office.
Her boyfriend, 32-year-old Kareem Ernesto Leiva, was also charged with murder, torture and one count of assault on a child causing death, a news release from the DA's office stated. He was arrested Wednesday on suspicion of murder.
Both are expected to be arraigned on the charges at the Antelope Valley Branch of Los Angeles Superior Court, prosecutors said.
News of the new arrest and charges came hours after family members held a news conference to demand transparency from officials in the investigation into the death of Anthony Avalos.
Attorney Brian Claypool, who represents the family members, appeared at the news conference asking the Los Angeles County Department of Children and Family Services to release all records reporting abuse of Avalos at his home, all findings resulting from those investigations, and any other reports of abuse of any other children at the home within the past five years.
"We are here today on behalf of Anthony to demand 100 percent transparency in the investigation of his death," Claypool said.
Claypool also asked the Los Angeles County Sheriff's Department to release all reports regarding abuse of any children at the home over the past five years and are demanding to see the autopsy findings from the Los Angeles County medical examiner.
Avalos was found unresponsive after his mother called 911 saying he had suffered a fall in their apartment in the 1100 block of East Avenue K on June 20. Avalos died the following morning.
Barron and Leiva are accused of torturing the boy in the days before he died, according to prosecutors.
The DCFS director said in a statement Tuesday that Avalos had evidence of "being a victim of physical abuse, including signs of being severely beaten, as well as malnourishment."
Sheriff Jim McDonnell said the description was "grossly overstated," but did confirm that investigators believe the boy died from abuse.
Family members want to know why Avalos was allowed to remain in the home despite years of documented abuse. Twelve referrals to the department were made for Anthony between February 2013 and April 2016, beginning with an allegation of sexual abuse that was later substantiated.
At one point Avalos was removed from the home and placed with relatives, but was later allowed to return.
Avalos recently told family members he liked boys, the Los Angeles Times reported, but investigators said homophobia has not yet come up as a motive.
"Anthony's dreams of becoming a police officer or a firefighter will never be fulfilled. But rest assured my sweet baby boy that you will always be loved … Anthony, you will always be in our hearts," Maria, who is an aunt of Avalos, said Friday.
Officials have confirmed that Leiva has a criminal history and gang ties, but said they were not enough to warrant the boy's removal from the home.
Eight other children have since been taken from the home.
If convicted, Barron could be sentenced to 22 years to life in prison, while Leiva faces a possible maximum sentences of 32 years to life.
