 ASAN's chapters work collaboratively with the national branch on nationwide projects; an example of this is Day of Mourning, an event on March 1 where local chapters of ASAN, as well as independent groups, host candlelight vigils in remembrance of disabled people murdered by their caregivers.The first campaign was suggested by Zoe Gross of California, who had heard of a case where a young autistic man was murdered by his mother, who later committed suicide.The vigils honor people with all kinds of disabilities.
