Where Is Fugitive Mom Who Fled to India After Police Say She Claimed She Sold Her 6-Year-Old Son?

Cindy Rodriguez Singh has not been spotted by law enforcement since she took an international flight out of Texas on March 22, 2023

When police knocked on her door on March 20, 2023, asking about her 6-year-old son, Cindy Rodriguez Singh allegedly told officers that he was in Mexico with his father.

Two days later, Rodriguez Singh, her husband and six children boarded a plane to India, according to authorities.

The missing child – Noel Alvarez – was not on the flight. He hasn't been seen since and is presumed dead.

Last week, the FBI and Everman police in Texas announced a $25,000 award for “information leading to the arrest and conviction” of the boy’s 39-year-old mother, who is charged with capital murder in connection with her son's case.

Police Chief Craig Spencer said in a statement that the mother’s “immediate capture” was “incredibly important” not only “in the interest of justice” but also for “the safety of the other children in her custody.”

Katie Chaumont of the FBI Dallas Division tells PEOPLE that the FBI – which is “working to locate” the mother, while the investigation into Noel’s death remains at the local level – has received multiple tips since the award was first offered and “will be vetting each one carefully for any information that may lead to Rodriguez Singh’s location.”

Noel has not been seen alive since October 2022, according to both law enforcement agencies.

The child was seen twice that month: once when his mother gave birth to twins and another time when he appeared “malnourished” and “unhealthy,” PEOPLE previously reported from a press release by law enforcement.

Relatives called police five months later, leading to the March 2023 welfare check.

Investigators claim they later disproved Rodriguez Singh’s claim that Noel had been with his biological father in Mexico since November 2022, PEOPLE previously reported, citing police.

On another occasion, authorities claim the mother allegedly told people who asked about her son that she had sold him to a woman at a grocery store parking lot.

But law enforcement believe the child is more likely dead.

Shortly after the birth of her twins, police have alleged that Rodriguez Singh called her son – who Spencer previously told PEOPLE in an interview had mental and developmental disabilities – “evil” and “possessed,” claiming a “demon” was inside the 6-year-old and that she believed he would hurt the infants, PEOPLE previously reported.

A month after the birth of the twins, the mother applied for passports for six of the seven children in the household — everyone but Noel, according to authorities.

While investigating the child’s disappearance, law enforcement determined that the family of 9 – who lived in a red shed in Everman, Texas – had destroyed a second shed on the property and poured a concrete patio where it once stood, according to Spencer, who characterized the demolition as being reflective of “very suspicious circumstances.”

Carpet recovered from the shed was sniffed out by cadaver dogs, which allegedly signaled the presence of human remains, leading to a warrant for investigators to rip up the concrete patio, according to Spencer, who said that a second set of detection canines alerted them that “there was at one time human remains inside the shed.”

Prior to Noel’s presumed death, the family lost custody of Noel and his siblings, who were placed in foster care, per Spencer, who said Noel was placed apart from his siblings in another foster home equipped for his special needs. Ultimately, social workers returned the children home.

Relatives believed Rodriguez-Singh to be “abusive and neglectful to Noel,” authorities previously claimed in a press release. One relative later reported seeing the mother hit the child in the face with her keys after he drank a sip of water, which multiple people told authorities was “often withheld” from the child – along with food – because she “did not like changing Noel's dirty diapers."

The mother also never enrolled her son in school, according to the police chief.

The United States District Court for the Northern District of Texas issued a federal arrest warrant for Rodriguez Singh on Nov. 2, 2023, after she was charged with unlawful flight to avoid prosecution.

Authorities say that Rodrgiuez Singh – who stands a little over 5 feet tall and has many tattoos – has ties to both India and Mexico.
