My wife had a friend who passed away at home, from cancer. By law (Illinois) the coroner had to come to her house and pronounce her dead. Alright, so far but while there he also confiscated every medicine in the house that had her name on it.
One would think taking the meds would be theft. Her estate should have demanded to see that law.
Was she in hospice? When my FIL was in hospice at home, the company provided all the morphine and valium. A dosage log was kept and they retrieved both the unused medication and the dosage log when he passed. Perhaps that’s what was happening here.
