The recently-arrested mother of a long-missing and presumed dead Texas boy is facing yet another felony charge in the Lone Star State.

In late August, Cindy Rodriguez Singh, aged 40, was arrested on a standing charge of capital murder involving a child under 10 years old, stemming from accusations that have pursued her for years.

Singh is the mother of Noel Rodriguez-Alvarez, a 6-year-old boy with disabilities from Everman, a suburb of Fort Worth, who vanished without a trace in the autumn of 2022. Authorities quickly surmised that the child had likely been killed. In October 2023, Singh was officially charged with murder, a little over a year after Noel was last seen alive.

On Monday, a grand jury in Tarrant County issued an additional indictment against the mother on a charge of abandoning a child without adequate care.

A representative for the Tarrant County District Attorney’s Office clarified in an email that this new charge is a second-degree felony. As reported by Law&Crime, Singh was already facing two counts of causing injury to a child and one count of deserting a child without any intent to return.

On Aug. 21, Singh was booked by authorities in Tarrant County on the murder charge and one count of repeat-offender DWI, jail records show.

Her capture occurred just under a month after she was included on the FBI’s “Ten Most Wanted Fugitives” list, making her the 537th individual to appear on this list.

Since November 2022, various witnesses have provided law enforcement with stories they attribute to Noel’s mother, each attempting to explain the little boy’s whereabouts. These stories and growing concerns drew the Singh family into law enforcement’s attention. However, formal charges were only pressed much later.

Then the family left the country.

Law enforcement learned Rodriguez-Singh boarded an international flight with a layover in Turkey, with India as the final destination, just two days before an Amber Alert was issued about Noel’s disappearance. Joining the defendant on that flight were her six other children and current husband, Arshdeep Singh, authorities say.

Several theories – such as human trafficking – supported the notion the boy was still alive. But those avenues of inquiry were quickly discarded and replaced by the belief he was killed by his mother.

Noel’s body has yet to be found. The cause of his presumed death remains unclear; a potential motive is similarly elusive – though occult-oriented explanations may feature in a criminal trial. Overall, physical evidence in the case has been nonexistent – at least in terms of what has been shared up to the point of her capture.

Noel suffered from a host of ailments that required attention and patience. He had not been seen for months by the extended family at the time law enforcement became involved. When initially contacted by police about her vanished son, Rodriguez-Singh said the child had been living with his biological father in Mexico since November 2022. Detectives later learned that was not true; the boy’s father had been deported before he ever had a chance to meet his son.

Eventually, all signs pointed to intentional homicide.

There is a concurrent civil case filed by Child Protective Services in Texas, according to Dallas-based Fox affiliate KDFW. That case aims to terminate Singh’s parental rights over her six other children. Last week, Singh appeared in family court for a hearing on that sealed dispute.

The defendant’s next court appearance for her criminal case is slated for Sept. 18. Singh is currently being detained in the Lon Evans Corrections Center on $10 million bond.
