SARASOTA - Prosecutors in the Carlie Brucia murder case released 526 pages of investigative documents Monday but the heavily redacted records offer little new information about the 11-year-old's death.
The documents include interviews with Carlie's stepfather, as well as the suspected killer's wife, roommates and friends.
They show how investigators tracked dead-end leads, including a non-human bone found in a parking lot.
The records do not include the medical examiner's report or investigative details that led to the arrest of car mechanic Joseph Smith.
Smith, 38, faces charges of first-degree murder, kidnapping and sexual battery.
Carlie was abducted Feb. 1 as she walked home from a friend's house in Sarasota. The kidnapping drew worldwide attention because it was recorded on a carwash video surveillance system and showed images of a man leading her away.
Smith was arrested Feb. 3 on drug-related charges, and Carlie's body was found three days later beneath a pile of brush at a Sarasota church.
The night Carlie was kidnapped, Smith visited the home of a friend, Christine Montalvo, for 15 minutes.
Montalvo told investigators Smith was alone and came over to give her a new clutch to repair her Mitsubishi.
"I'm still in shock because I would never have thought that he would do something like that, if he did do it," Montalvo told investigators. Portions of Montalvo's interview were redacted.
Smith was separated from his wife and living with friends near his home at the time of Carlie's disappearance.
Before Carlie was kidnapped, Smith borrowed a yellow station wagon from one of his friends, Jeffrey Pincus. The vehicle was seen in the carwash images.
Smith told Pincus he would be gone 15 minutes but returned 16 hours later. The car had an additional 382 miles on it.
Investigators asked Pincus how Smith acted when he returned the car.
"Like he had a good night sleep or he's real happy," Pincus said. "I didn't ask him... He just looked like he had a wonderful night."
Upon seeing the carwash images, people started calling investigators. They told authorities the man in the images was Smith.
"The white sneakers, the uniform, the back side of the uniform," a friend of Smith's, Ed Dinyes, told investigators. "I didn't even have to see the front side of the uniform. The haircut and the way the person walked. It was his gait."
On Feb. 2, the day before his arrest, Smith visited his wife, Luz Castrillion-Smith, and their children. She told investigators Smith did not act unusual.
"It's just so overwhelming," she told investigators, according to a partially redacted transcript.
