Louisiana foster child death investigation

In late July 2026, the death of 18‑month‑old foster child Melanie Trahan in Beauregard Parish, Louisiana, prompted a multi‑agency investigation. The child was transferred from a local hospital to a Baton Rouge facility, where she died after autopsy revealed multiple brain hemorrhages at different stages of healing, suggesting prior abuse. The investigation involved the Beauregard Parish Sheriff’s Office, the Calcasieu Parish Sheriff’s Office, and the Louisiana Department of Children and Family Services, which examined staffing and management issues within the state child‑welfare system.

A week later, authorities arrested and charged Alberto Marin, a 31‑year‑old Utah resident serving as a foster father in the parish, with second‑degree murder and obstruction of justice. Prosecutors cited the same autopsy findings and noted a prior incident at Marin’s home in August 2025 involving an infant with severe respiratory distress that had not been reported to law enforcement. The case continued to be handled by the Beauregard Parish Sheriff’s Office, with Detective Sylvester Denmond confirming the ongoing investigation.
