Susan Schneider and Robin Williams were sleeping separately when he died

Susan Schneider, Robin Williams’ wife of three years, was sleeping in a nearby bedroom at the moment of his suicidal act, the police confirmed.

Robin Williams, 63, was not discovered until the following morning by his personal assistant, after Susan Schneider had left the house to run some errands, believing her husband to still be asleep.

During a police press conference earlier today, Marin County sheriff’s department Lt. Keith Boyd, said that Robin Williams had been last seen at around 10.30 PM on Sunday night by his third wife, Susan Schneider, at their home before she went to bed.

It was not confirmed by the police that it was a normal arrangement for the couple to sleep separately, but the Lt. Keith Boyd said that Susan Schneider did not know what time Robin Williams had gone to bed, and his body was discovered in a separate room in the house.

Susan Schneider returned to the family home shortly after emergency personnel arrived at the house, where they pronounced Robin Williams dead at 12:02 local time. Police officials said that Susan Schneider was made aware of Robin Williams’ death prior to returning to their home.

Police would not confirm if a suicide note was found at the scene, but did say they were carrying out a toxicology report for which results could take up to six weeks.

Susan Schneider paid loving tribute to her ”husband and my best friend” saying: “This morning, I lost my husband and my best friend, while the world lost one of its most beloved artists and beautiful human beings.

“I am utterly heartbroken. On behalf of the Robin’s family, we are asking for privacy during our time of profound grief.

“As he is remembered, it is our hope the focus will not be on Robin’s death, but on the countless moments of joy and laughter he game to millions.”
