Investigators on Sunday were interviewing several people, but no suspects had been named by late afternoon. Detectives were checking out tips that had come in to the sheriff's office, including possible leads from outside the county, officials said.
"It's just terrible," resident Paul Gschweng told Sacramento television station KCRA. "What can I say about it, it's just a tragedy."
The station reported that a neighbor told police that a man was running from the girl's home after the attack.
Investigators were asking area residents to call authorities if they had any information, knew of anyone who had unexplained injuries or may have left the area unexpectedly after the girl was killed.

The boy reportedly said he found his sister as the intruder who stabbed her to death was leaving his house. Police said the boy is not a suspect "at this time, but we are continuing to talk to him."
Cpt. Jim Macedo said investigators collected fingerprints and what they believe to be DNA at the scene.
The station reports two other witnesses gave the same description as the victim's brother, describing the suspect as wearing blue jeans and a dark shirt.
