Union County major crime team investigates infant death in La Grande

A 3-month-old infant’s death on Q Avenue drew more than 10 investigators, state police detectives, county prosecutors and child-welfare officials into one La Grande case. Officers with the La Grande Police Department and medics from the La Grande Fire Department responded to a 911 call from a residence in the 2300 block of Q Avenue at about 9:57 p.m. June 17 after the infant was reported not breathing.

The Union County Major Crimes Team was activated under established death-investigation protocols, moving the case beyond a routine emergency response and into a broader inquiry that can bring in multiple agencies and specialized resources. In this case, the team included personnel from the Oregon State Police, the La Grande Police Department, the Union County District Attorney’s Office and Child Protective Services, with more than 10 investigators involved in the initial response and follow-up work.

Investigators were interviewing witnesses, preparing search warrants and coordinating an autopsy as the inquiry moved forward. At that stage, officials had not determined the cause or manner of death, leaving open whether the death was accidental, natural or involved criminal conduct. No arrests or additional public details about the infant or family had been announced.

The case fits the county’s formal death-investigation structure. Oregon law assigns the district medical examiner and the county district attorney responsibility for deaths that require investigation, and each Oregon county must maintain a child death review process. In Union County, the district attorney’s office administers the county medical examiner program and chairs the county multidisciplinary child abuse team, which is why a case involving an infant quickly draws in law enforcement, prosecutors and child-welfare partners.

The Union County Major Crimes Team is a standing regional unit made up of the Union County Sheriff’s Office, La Grande Police Department, Oregon State Police and the Union County District Attorney’s Office. Oregon State Police detectives are stationed across the state to support local agencies in major criminal investigations, and the county’s child-death review system is designed to bring those findings together after the immediate investigative work is complete. In the days ahead, residents can expect updates tied to the autopsy, witness interviews and any warrant-related findings, with prosecutors positioned to decide whether the case remains a death investigation or moves toward court action.
