The mother of a 5-year-old girl was arrested after her daughter’s decaying body was found in a closet inside a Houston apartment, according to police.

Priscilla Torres, 27, was charged Tuesday with tampering with evidence in connection with the death of her daughter, Sierra Patino, who was discovered dead Monday when visiting relatives smelled a sickening odor inside the residence.

Torres is suspected of “having a role” in the girl’s death and could face additional charges, police said in a statement.

The relatives stopped by Torres’ apartment after not seeing her daughter for several days. When they noticed the foul odor, Torres acknowledged that the girl’s body was inside the closet, police told the Houston Chronicle.

Investigators are awaiting results of an autopsy to determine the cause of death. It’s unclear whether Sierra died from an accidental or deliberate act, but Torres allegedly confessed that her daughter died Aug. 27 after ingesting chemicals — some six days before she was found, police told KRIV.

Torres initially said in court Tuesday that Sierra died after drinking a bottle of toilet bowl cleaner, but then switched her story to implicate her boyfriend — saying he was giving the girl a bath as she prepared dinner and returned to find her body covered with chemical burns, according to the station.

Torres said she kept the girl wrapped up in blankets and inside a closet for four days before she died, because she was afraid she’d lose custody of her daughter if she sought medical help, the station reports.

“No matter how the child died, whether it was accidental or an intentional death, you know for a body to be in a closet for several days, it’s just, it’s pretty unthinkable,” Houston police Lt. Larry Crowson told the station Monday. “We’re not sure of the circumstances.”

Firefighters who responded described the girl’s body as being in a state of decay and blocked it from the view of witnesses, KTRK reports.

A spokeswoman for the Harris County Institute of Forensic Sciences said the girl’s autopsy was scheduled for Tuesday, but a cause and manner of death was not available early Wednesday, records show.

Child welfare officials have not had any prior contact with Torres’ family and Sierra had no siblings, according to the Houston Chronicle.

Torres’ Facebook profile identifies her as a stay-at-home mom and features video of her daughter dancing with another young girl in June.

“Sierra Makayla Patino is my everything,” the profile reads.
