The 31-year-old, originally from the NSW Central Coast, reportedly 'appeared surprised' when Judge Susan Speer told him if found guilty, despite his claim of being insane, he could spend the rest of his life locked up in the California state hospital system.
"Still?” Haywood replied, news.com.au reports.
The court will hear that Haywood went to Kerr's home to deliver a letter, where he confronted a security guard.
Hayward is accused of grabbing the security guard’s knife and slashing the guard in the face.
The guard responded by shooting Hayward, according to authorities.
Kerr, who has since married Snapchat billionaire Evan Spiegel and welcomed the couple's first child, no longer lives at the Malibu residence.
