Human remains found in the search Aniah Blanchard have been confirmed as UFC star Walt Harris’ missing stepdaughter.
The remains were found in woodland on a county road in Macon County, south Alabamba, after a month of searching.
Investigators are now treating the 19-years-old’s death as murder.
Police have arrested three people over the disappearance of the 19-year-old, who was last seen on October 23 in the city of Auburn.
Her black Honda car was found abandoned more than 50 miles away at an apartment complex in Montgomery, Alabama.
Auburn police detective Josh Mixon said Ms Blanchard’s blood was found in the car and it appeared she had suffered a life-threatening injury.
Mr Mixon said convenience store video footage showed a man buying a beverage look over at Ms Blanchard.
He said sources later identified the man as Ibraheem Yazeed, 29, and a man at the store told investigators he saw Yazeed force Blanchard into her car and drive away.
Police have arrested Yazeed and a second man, 35-year-old Antwain Shamar Fisher, of Montgomery.
In an arrest warrant filed with the court on Monday, police said Fisher helped Yazeed by disposing of evidence and driving him.
Mr Hughes said a third man, David Johnson Jr, was arrested on Monday in Montgomery and charged with hindering prosecution in the case.
The discovery of human remains came after a month-long search for the missing teenager whose face appeared on billboards across the county.
Auburn Police said on Monday that investigators “obtained information regarding the possible location of a body”.
Law enforcement officials searched a wooded area in Shorter, Alabama, and found what appeared to be human remains several feet into the woods.
Auburn Police chief Paul Register reportedly said: “We have spoken with the family, obviously they’re heartbroken, but at least they can now begin to deal with this and move forward and plan for dealing with it.”
