My mother in law passed away at home in her sleep without a known cause. Police came and filed a report, someone took her body away (coroner or medical examiner). But they were so busy maybe cause of covid that they didn’t create a death certificate. Now three weeks later we don’t have a death certificate and are having a hard time getting one. She was 89 years old and didn’t have a regular doctor and her heart specialists says they don’t issue one if they hadn’t seen her lately. Her body is stored away and can’t be cremated until we have a certificate. What can we do?
