The incident reportedly happened Jan. 26 or Jan. 27, inside an Annette Drive home belonging to her mother's family. Riego is originally from Buras but apparently was residing at the home, authorities have said.
The infant's maternal family reportedly told the Jefferson Parish Sheriff's Office she slept with Riego overnight. But early on Jan. 27, a relative who went into Riego's bedroom noticed the infant "was limp, gasping for air," Detective Travis Eserman testified during a March 12 hearing in the 24th Judicial District Court.
She was later reportedly declared brain dead, caused by "unaccidental trauma," Eserman testified. The autopsy confirmed "closed head trauma consistent with shaken baby syndrome," he testified.
Riego was initially booked with second-degree cruelty to a juvenile, then reportedly booked with an additional murder charge after Madison died. The Jefferson Parish district attorney's office declined to pursue the cruelty charge, "because that's encompassed in the murder charge," Assistant District Attorney Sunny Funk said.
Riego reportedly admitted he shook the baby, but only after the autopsy, Eserman testified. "He told us he knew we wound find something at autopsy," Eserman testified. "He knew that he caused it."
Riego is held in the Jefferson Parish Correctional Center in lieu of a $1 million bond, Funk said. His case has been assigned to Judge Hans Liljeberg's court, records show. The case record does not reflect whether he has an attorney. His arraignment is expected to be Friday.
Second-degree murder carries a mandatory life sentence with no probation, parole or suspended sentence.
