A 25-year-old man who appeared on NewsChannel 5 in May to discuss his experience with Flakka is now missing and considered endangered by the Palm Beach County Sheriff's Office.
Tyler Etue has been missing since the end of July.
A Palm Beach County Sheriff's deputy found remains Wednesday near where he was last seen, but it is unclear if the remains are connected to Etue.
"My greatest fear is something has happened. But I still have the hope and cling to the hope that he is going to come back," Etue's former girlfriend Anna Anderson said.
Anderson is carrying Etue's baby.
"We had already named her. He wouldn't say the baby. He would say her name. He would say little baby Natalia," Anderson said.
The human remains found Wednesday were in a trash can on South L Street in Lake Worth.
A Palm Beach County Sheriff's Office spokeswoman says investigators have discovered three sets of remains over the last several weeks. It is unclear who the remains belong to.
The Palm Beach County Medical Examiner's Office is also investigating.
If you have any information about the whereabouts of Etue, call the Sheriff's Office or Crime Stoppers at 800-458-TIPS.
