No one did the check ins specified in care plan. Cops were there when my sister got there. Sister called at 1030 no answer, she then called AL staff to check---They said she had probably fallen, got tangled in her gown?.. the staff put her back in bed before the cops and sister came. Now they say she has to go to the medical examiners office to determine cause of death. Is that usual? Also- the routine early am nursing check on mom per her care plan was ignored today- no one came by- Is the Al facility liable for something here?
