Investigators are still searching for any leads in the Anthony Lombardi homicide.

Three Hart High School boys found Lombardi stabbed to death and his bloody body slumped in his Honda Accord in his driveway Sept. 16.

Detectives questioned family members and neighbors and collected some clues, said Lt. Dave Coleman of the Los Angeles County Sheriff's Homicide Bureau. Deputies aren't releasing those clues to preserve the integrity of the case, Coleman said.

Anyone with information about the case can call the Homicide Bureau at 323-890-5500.
