Police who searched the torched home of kidnapping and murder suspect James Lee DiMaggio found firebombs, ammunition, used condoms, and "letters from Hanna," court documents show.
The new details emerged as Hannah Anderson, the teenager DiMaggio took to the Idaho wilderness after killing her mother and brother, arrived at a fundraiser Thursday — her first public appearance since her abduction.
Flanked by protective friends and family, the 16-year-old did not speak as she entered the Boll Weevil restaurant near San Diego.
"Right now, she's with her family and, of course, with some friends, and she's just happy to be here," Hannah's father, Brett, told reporters outside the restaurant. "Hannah sends her love. She’s doing good day by day. We’ll just keep moving forward from here."
Earlier in the week, Hannah answered questions on a social media website Ask.fm, saying she was glad cops shot and killed family friend DiMaggio when they rescued her.
Search warrants unsealed this week show police believe DiMaggio "tortured and killed" Hannah's mother, Christina Anderson, and her 8-year-old brother, Ethan, before burning down his cabin-style home in Boulevard.
Court papers obtained by NBC San Diego cataloged dozens of items investigators seized from the burned-out property as a manhunt for DiMaggio and Hannah began to unfold.
They range from mundane articles like gravel and tape to the crowbar that police believe DiMaggio, 40, used to bludgeon Christina Anderson, and the tarp that they say covered her body.
A DNA swab test kit was found inside Christina Anderson's burned-out car, NBC San Diego reported.
The court documents don't spell out the significance of the items seized from the suspect's house. They include a gas can, empty ammunition boxes, shotgun shells, a handcuff box, incendiary devices, and something described as "arson wire."
No. 37 on the list was "D & C letters from Hanna" — with no confirmation that referred to Anderson or any details of what the letters said.
Police have not revealed a motive for the double slaying and abduction.
When authorities found DiMaggio — thanks to four horseback riders who encountered him and the teen in the Idaho back country — he fired one shot before being killed with five bullets.
Andrew Spanswick, a friend of DiMaggio's family, believes he was suicidal and may have planned to take his own life around the anniversary of the death of his troubled father, who killed himself 15 years earlier.
Spanswick said the family collected skin, hair and blood samples from DiMaggio's body before he was cremated to run toxicology tests that could shed light on his state of mind.
After her rescue, Hannah was reunited with her father and returned to the San Diego area. The restaurant where the fundraiser was held is owned by the mother of one of her schoolmates.

"This is a small community that we're a part of, and the community came together and put on this great fundraiser for Hannah and her future and healing," Brett Anderson said at the event, according to NBC San Diego.
Hannah's father said he has been in touch with the horseback riders whose tip led police to DiMaggio and thanked them.
"It was a chance encounter but it did save my daughter’s life," he said.
