The parents of a baby killed in 1992 are in custody after newly developed DNA evidence led investigators to them, state troopers said.

A farmer in Picayune, Miss., looking to feed his animals, found the infant’s body on April 17, 1992, in a trash bin inside a bag wrapped in a towel with other garbage. An autopsy showed the baby was most likely born the morning on which it was found. It also revealed the baby was around three weeks premature and lived a few minutes before being smothered.

The cause of death was determined to be perinatal asphyxia because of smothering, and the case was classified as a homicide.

Picayune Police reopened the case in August 2021. With advanced DNA technology, officials were able to develop their first suspects, building profiles and fingerprints from preserved evidence.

Inga Johansen Carriere, 50, of Avondale and Andrew K. Carriere II, 50, of River Ridge, are facing charges of first-degree murder. They are being held without bond at the Jefferson Parish Correctional Facility and await extradition to Mississippi. It was unknown if either of them has an attorney who could speak on their behalf.

The investigation between the Mississippi Bureau of Investigation, Louisiana State Police and Picayune Police determined that the crime took place in Louisiana and the body was dumped in Mississippi. The unidentified infant was buried at Lee’s Chapel Baptist Church with a headstone donated by the community that read “Heavens Angel.”

“This breakthrough in the case is a testament to the advancements in forensic technology and the dedication of law enforcement agencies to bring justice to victims and their families,” state police said in a news release.
