The Wisconsin 14-year-old accused of luring, killing and then sexually assaulting 10-year-old Iliana "Lily" Peters in April waived his right to a preliminary hearing Thursday before his attorney announced he is looking to have the case transferred to juvenile court.

The juvenile suspect is being identified only with his initials, CTB-P. and was initially charged as an adult. He has pleaded not guilty.

Preliminary hearings are held for prosecutors to convince the court they have enough evidence to go to trial.

Defense Attorney Michael Cohen did not immediately respond to messages seeking comment. In court Thursday, he said he would be filing a reverse waiver, records show. The reverse waiver filing would ask the court to send the 14-year-old's homicide case to juvenile court.

Lily vanished on the way home from her aunt’s house on April 24. She left on her bicycle, headed for her father's house nearby.

CTB-P allegedly told police he lured her off the trail home and into the woods, then punched her in the stomach and beat her with a stick or club before strangling her, according to prosecutors. Then he allegedly sexually assaulted her body.

He allegedly went home, changed his clothes and then returned to conceal the body under some leaves.

Search teams found her bike discarded in the woods, and then on April 25, investigators discovered her remains nearby.

"The suspect was not a stranger," Chippewa Falls Police Chief Matthew Kelm said during a news briefing after CTB-P’s arrest. "The suspect was known to the victim. We do not believe there is any danger to the community at this time."

The juvenile suspect has been charged as an adult with intentional homicide and was being held on $1 million bond.

"Protection of [the] community also is necessary in this case given his statements regarding his intentions and his statements regarding that when he did get off the trail, he punched the victim in the stomach, knocked her to the ground, essentially strangled her, hit her with a stick, before strangling her to the point of death -- before he then sexually assaulted her," Chippewa County District Attorney Wade Newell told the judge at an April 27 bond hearing.

Newell’s office said it had no additional comment after Thursday’s appearance.

The suspect was being held in a juvenile detention facility and appeared in court remotely.
