(2)(a) The county coroner, upon knowledge that a body is of an indigenous person, shall make reasonable efforts to identify and contact family members prior to entrusting the body to a funeral home, including an attempt to facilitate contact through the regional liaison for missing and murdered indigenous persons pursuant to RCW 43.43.874 within 10 days of the county coroner having jurisdiction over the remains.
