(NBC News) — The search for a missing 6-year-old Texas boy who has not been seen for months is now a death investigation, police in Everman said Thursday.

The boy, Noel Rodriguez-Alvarez, was last seen in October at a hospital when his mother, Cindy Rodriguez-Singh, was there to give birth to twins, police said.

Police conducted a welfare check March 20 at the family’s home, but Noel was not there. Two days later, Rodriguez-Singh, her husband, and six other children got on a plane and traveled to India, Everman Police Chief Craig Spencer said.
