Miranda Kerr Intruder Delivered Love Note Before Attack

The intruder who was shot at Miranda Kerr's home left a bizarre calling card/love letter at the house 2 days before his bloody confrontation ... TMZ has learned.

Our law enforcement sources tell us Shaun Haywood hand-delivered a letter to an employee at Kerr's home, and it was filled with nonsensical phrases. We're told the only thing that was clear from the "jibber-jabber" was Haywood had a thing for Miranda.

The employee who received the letter alerted security, which was immediately increased at the home ... leading up to the bloody confrontation with Kerr's security guard. Our sources say Haywood told cops he believed he was a spirit traveling for thousands of years, and wanted to meet Miranda because she's also a free spirit.

A judge has since issued a protective order for Haywood to stay away from Miranda. He won't be a problem for now, as he's still in police custody. He's been charged with 3 felonies.
