Investigation and Scene Details

During the investigation at the South Carolina property, authorities recovered blue pressed pills and a straw that subsequently tested positive for fentanyl (TMZ). Additionally, officers discovered white powder stored inside a sunglasses case at the location (Extra). Following the coroner's findings, the Drug Enforcement Administration (DEA) initiated an active investigation into the source of the fentanyl (NBC News).

Prior to her passing, Panettiere had completed a stint in rehab just weeks before the incident (Hola). Public records and reports note that she also maintained a documented history involving addiction and postpartum depression (E! Online).

Family members have since released statements describing Panettiere as a fighter while openly acknowledging her struggles with substance use (The Nightly).

Ongoing Federal Inquiries

The Drug Enforcement Administration and local authorities continue their active investigation into how the controlled substances were acquired, with official findings pending further federal review (NBC News).
