Vehicle of missing disabled boy's family found at airport, authorities say

A vehicle belonging to the family of a missing Texas boy who has severe developmental and physical disabilities has been found abandoned at DFW Airport, CBS Texas' Olivia Leach and Alexis Wainwright report.

Authorities say they turned an Amber Alert for six-year-old Noel Rodriguez-Alvarez, of Everman, a Dallas-Fort Worth suburb, into an Endangered Missing Persons Alert on Saturday night.

"I need to be very clear that we currently do not have any physical evidence related to Noel's status as a missing person. What I do know is that we have a six-year-old disabled boy [who] cannot be accounted for," said Everman Police Chief Craig Spencer.

Everman police say they learned Saturday night that Noel's mother, Cindy Rodriguez-Singh, his stepfather and Rodriguez-Singh's six other children had boarded an international flight.

"At approximately 9 p.m. last night, we learned that the mother, stepfather and siblings had all left the country on a Turkish Airways flight to Istanbul that flew out on March 23," said Spencer.

Noel wasn't listed as a passenger on the flight.

Child Protective Investigations (CPI) asked Everman police on Thursday evening to conduct a welfare check on Noel at the family's home, Spencer said.

Cindy Rodriguez-Singh told police Noel was with his biological father in Mexico. But CPI found out that wasn't true. Family members also told CPI they hadn't seen Noel since November.

"It appeared to the CPI investigator that the mother was intentionally avoiding authorities," said Spencer.

"(CPI) informed us that they had attempted to make contact with the mother of the child and had learned that she had taken the children from school and had not returned to school that day. That's when the concern began," Spencer disclosed.

He told a news conference Sunday that CPI had prior investigations and actions against Cindy Rodriguez-Singh.

Police have obtained an arrest warrant for her for allegedly giving a false report about a missing person.
