Rawlings died on the night of January 11 at Sivia's home in Southmoor village. An inquest heard this week that Rawlings had been mentally ill for a year and died as Sivia defended himself during a violent psychotic attack.
Rawlings' final words were: "goodbye cruel world." But, in a surreal twist, Sivia thought he was playacting.
"This is a line from a Pink Floyd song, Goodbye Cruel World, from their album The Wall. I thought this might be a ploy to release him because it was so melodramatic," said Sivia, who came to Britain from India at the age of five.
