A witness told deputies that a Naples man stabbed her children as they slept Wednesday after his withdrawal from synthetic cannabis.

Collier County Sheriff's Office reports that deputies arrested Trevor Hooper Kilian, 47, on two counts each of attempted murder and child abuse charges.

The incident occurred about 10 p.m., an hour after the children went to bed, in the Ibis Cove community off Immokalee Drive, in Naples. 

A woman in the home told deputies that Kilian had used synthetic cannabis but had stopped approximately two weeks ago. He began having manic episodes and wasn’t eating or sleeping.

About 10 p.m. Kilian left the couple's bedroom and moments later she heard the children screaming. She went to them and saw Killian standing in the hall with a knife.

“I stabbed them, I stabbed them. What have I done,” he told her, according to the arrest report.

She barricaded the children and herself in the bedroom, calling authorities.

Deputies arrived and secured the scene, an arrest report indicated. One child was stabbed twice in the back, the other stabbed once in the chest, with both having collapsed lungs.

“Deputies quickly responded, entered the home and pulled the injured children out to the ambulance that was waiting,” Sheriff Kevin Rambosk said. 

Deputies found Kilian on the floor of the master bedroom with what appeared to be severe self-inflicted lacerations on both arms, according to the arrest report. Deputies found knife in the room.

Kilian and the children were hospitalized with serious injuries. Emergency personnel flew the children to Gulf Coast Medical Center in Fort Myers, the report indicated, where they were "stable". They took Killian to North Collier Hospital, where they placed him under arrest.

Deputies did not release the names or ages of the children or the witness.

According to the National Institute on Drug Abuse, synthetic cannabis, also known as synthetic cannabinoids, are manmade mind-altering chemicals that are smoked or sold as liquids to be vaporized and inhaled, the sheriff's office reported.
