The Louisiana State Police Bureau of Investigations – New Orleans Field Office received a request for assistance from the Mississippi Bureau of Investigations on Jan. 6, 2022, regarding a cold case homicide investigation. The case in question involved the discovery of a female infant’s body inside a garbage bag in Picayune, Mississippi, on April 17, 1992. The Mississippi State Medical Examiner determined that the cause of death was perinatal asphyxia due to smothering, and the case was classified as a homicide.
The Picayune Police Department initiated a homicide investigation and collected various pieces of evidence, some of which were linked to associations in Gretna, Louisana. All evidence was preserved by the Picayune Police Department.
In August of 2021, the Picayune Police Department and Detectives with the Mississippi Bureau of Investigations Detectives reopened the investigation. With the help of advanced technology, DNA profiles and fingerprints were developed from the preserved evidence. Through investigative means, detectives were able to identify the infant’s parents as 50-year-old Andrew Carriere and 50-year-old Inga Johansen Carriere, who were living in Louisiana at the time of the death.
As a result of the investigation, LSP Detectives obtained an arrest warrant through the 24th Judicial District Court for both Inga Johansen Carriere and Andrew Carriere for First Degree Murder. On Feb. 28, 2023, Inga Johansen Carriere was arrested at her residence in Avondale, Louisiana. On March 9, 2023, Andrew Carriere was arrested in Galliano, Louisiana and ultimately booked into the Jefferson Parish Correctional Center.
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.
