(CBS) - The FBI and Department of Justice officials are aiding an investigation into the death of 13-year-old middle school student Genelle Allen-Conway, whose naked body was found at a California park Friday, Fairfield police said Wednesday.
Police released little new information at the news conference, but did clarify what they called "misinformation," CBS Sacramento reports.
Fairfield Police Chief Walt Tibbet said a previous report that detectives are looking for a silver minivan connected to the crime is not accurate and neither is a report that police were prepared to provide a sketch of the suspect.
Tibbet also said releasing the cause of death of Genelle Conway-Allen would be "hurtful to the investigation" and "devastating to the family."
According to the San Francisco Chronicle, Tibbet would not label Genelle's case an abduction, saying he didn't want to create panic.
Genelle was reported missing Thursday evening by her foster home guardian, CBS San Francisco reports. Police said her naked body was found in a parking lot near Allan Witt Park around 6:45 a.m. Friday, a few miles away from an intersection where she was last seen.
Investigators previously released a video image that captured Genelle minutes before she disappeared, Sgt. Matthew Bloesch said. The image showed Genelle at the Fairfield intersection wearing a gray sweater, blue jean-style leggings and a pink backpack.
Genelle was a student at Green Valley Middle School, CBS San Francisco reports.
At the news conference, police released a statement from Genelle's family.
"This has been a devastating tragedy for our family and community. We need to thank everyone for the outpouring of support at the memorial site," the family says in the statement.
Anyone with information in the case is urged to call the 24-hour tips line at (707) 428-7345.
