Ty Carey, Margot's grandfather, told the news station he was grateful authorities decided to put her "back where she belongs -- with her family."
"A child needs to be -- especially at that age -- needs (the) voices and smells of familiarity," he said.
Authorities have arrested a 33-year-old woman once described by Broussard as her "best friend" on charges believed to be connected to the Texas mother's disappearance, according to the Austin American-Stateman. Magen Rose Fieramusca is facing two counts of kidnapping and one count of tampering with a corpse.
Officials told the American-Stateman that Fieramusca faked a pregnancy concurrent to Broussard's and kidnapped her and her daughter after Margot's birth. Authorities have not officially identified Fieramusca as a suspect in Broussard's death.
