Adoptive mother concealed 9-year-old daughter’s remains in attic as other children endured abuse

The investigation eventually led to Maribel Loera’s guilty pleas and a 32-year prison sentence for murder and child abuse.

PHOENIX, Az. — The criminal case that ultimately sent Maribel Loera to prison for 32 years did not begin with the discovery of a body or a homicide report. It began Jan. 20, 2020, when an 11-year-old girl called 911 from a west Phoenix home and told police she had been left alone, was hungry and needed help. Within days, children were removed from the home, the house burned and firefighters found another child’s skeletal remains in the attic.

Nearly seven years later, Loera, 57, has been sentenced for second-degree murder, concealment of a body and nine counts of child abuse. Maricopa County Superior Court Judge Brad Astrowsky imposed the 32-year prison term on Oct. 16 after Loera entered guilty pleas in September. The victim is identified in the latest court coverage as 9-year-old Charisma Marquez, also known as Ana Loera after her adoption. The sentencing resolved Loera’s prosecution but left a separate case against her husband, Rafael Loera, pending.

Police responding to the 11-year-old’s call in January 2020 encountered allegations that immediately raised concerns about the safety of children in the household. The girl told authorities she had been left without adequate care and described physical abuse. The Arizona Department of Child Safety removed her. Investigators continued looking into the home, and on Jan. 28 child welfare officials removed two additional children. That intervention came only hours before the next event transformed the investigation.

Smoke was reported at the family’s house near 59th Avenue and Camelback Road later that day. Fire crews entered the home and worked on the structure. During the response, firefighters discovered what appeared to be human bones in the attic area. Police were called back to the scene, and the remains were eventually identified as those of a child who had been missing from the household for years. The fire was determined to have been intentionally set.

The discovery forced investigators to reconstruct a period that had passed without a reported death. Rafael Loera told investigators that the adopted girl had become ill and that he waited before attempting to obtain medical attention, according to accounts based on court and police records. He said she died while he was taking her toward a hospital and that he brought the body back to the house instead of notifying authorities. He told investigators that the death was concealed because he feared the other children would be taken away.

Investigators did not simply adopt that account as the final timeline. Rafael had placed the death in 2017, but witnesses had reportedly last seen the girl earlier, and prosecutors later alleged that Charisma died sometime between May 1 and Nov. 24, 2016. The differing accounts contributed to uncertainty in early public reporting. Authorities initially described the remains as those of a 13-year-old girl. More recent reporting from the plea and sentencing proceedings identifies Charisma as 9 years old. The later reports also identify her by both her birth name and her adoptive name, Ana Loera.

As detectives worked through the death investigation, they also documented allegations involving the children who survived the household. Police and child welfare findings led to arrests and child abuse charges against Maribel and Rafael Loera in 2020. In 2021, authorities announced murder charges in connection with Charisma’s death. The case then moved through years of pretrial proceedings while both defendants remained tied to separate allegations concerning what occurred before and after the child died.

Maribel Loera’s case changed course in September 2026. Rather than proceed to a trial where she had faced a first-degree murder charge and the possibility of capital punishment, she entered a negotiated guilty plea to second-degree murder, concealment of a dead body and nine child abuse counts. The agreement established a lengthy prison term and lifetime supervision. It also meant prosecutors would not have to prove the charges against her to a jury, because Loera admitted guilt as part of the plea.

The Oct. 16 sentencing hearing returned the case to the children whose removal had helped expose it. Surviving siblings described severe abuse and lasting trauma. Angelina Ariza remembered Charisma as an older sister who tried to comfort and protect younger children. Joseph Marquez described seeing Charisma being attacked and recalled hiding afterward. Their statements gave the court a picture not only of the criminal conduct admitted by Loera, but also of the effects the household had on children who were still young when police first entered the home in 2020.

Charisma’s birth mother, Priscilla Marquez, addressed the judge as well. She opposed the agreement that removed the death penalty from consideration and spoke about the life her daughter did not get to live. Marquez said she had lost custody of her children during an earlier struggle with addiction and had believed the placement that followed would give them greater safety. She said she later learned of her daughter’s death through news coverage and carried deep guilt about what the children experienced after leaving her care.

Astrowsky said the case involved aggravating circumstances including the age of the victim, the presence of multiple victims and the violation of trust created by Loera’s position as a parent. He nevertheless said he believed her acceptance of responsibility was genuine. Loera spoke through an interpreter and apologized to the victims for the physical and emotional damage she caused. The judge sentenced her to 22 years on the murder count and another 10 years tied to child abuse convictions.

Loera received credit for 2,453 days she had already spent in jail, according to reporting from the Arizona Republic. The plea also calls for lifetime probation after imprisonment on applicable counts. The sentence means one branch of the prosecution has reached a final judgment. It does not establish the criminal liability of Rafael Loera, whose case continues independently and whose statements to investigators have appeared throughout police and court accounts of the investigation.

Rafael Loera has pleaded not guilty and is expected to face trial in March 2027. He has been accused in connection with the homicide, abuse, concealment of the body and the intentionally set fire, but those allegations remain unresolved in his case. The distinction matters because Maribel Loera’s guilty pleas cannot substitute for a verdict or plea concerning her co-defendant.

The investigation therefore remains unfinished even though Maribel Loera has been sentenced. Its path can be traced back to a single emergency call from a child in January 2020. That call brought police into a home where children reported abuse, led child welfare officials to remove others and set in motion the scrutiny that preceded a fire and the discovery of Charisma’s remains. The next major court proceeding is expected to be Rafael Loera’s trial in 2027.
