First reactions were inevitably grief stricken, as Williams was one of the most recognizable entertainers in the world, universally beloved for both his gut-busting comedy and his award winning dramatic acting.
Details at first were sketchy, referring to the death as being caused by "asphyxiation", which is just a fancy word for hanging.
Naturally, in such a high profile case, conflicting reports streamed out immediately, but, by Tuesday afternoon, most of the important details had been nailed down, with a timeline of the comedian's last hours loosely established.
That's where things start to get tricky.
After a midday news conference was held Tuesday, some known facts about the Robin Williams suicide were revealed by police and published by The Hollywood Reporter, with this tantalizing detail included:
"Williams was last seen alive by his wife (Susan Schneider) at approximately 10:30 p.m. on Sunday, before she went to bed. Around 10:30 a.m. the next morning, Williams' wife left the house, believing Williams to still be asleep, but his assistant grew concerned around 11:45 a.m. when Williams did not respond to repeated knocks on his bedroom door."
The question is, after 12 hours sleep, wouldn't Robin Williams' wife look in on him before leaving the house? Especially if he'd been "battling depression" lately, as was persistently reported almost from the first moment the story broke.
In cases like this, with a star as big as Robin Williams involved, details and facts will be coming out slowly over the coming weeks and even months. All kinds of forensics evidence will be examined and an autopsy will be performed to find the true cause of the unnatural death of one of the greatest entertainers in history.
But, police should keep in mind, especially in Hollywood, that not all suicides are as cut and dried as they look.
