OKLAHOMA CITY - Authorities say they have arrested two teenagers for murder related to the disappearance of a Piedmont girl.
Investigators arrested 16-year-old Chadd Raymond and 17-year-old Chloe Thomas for first-degree murder related to the disappearance of Anne Hill.
Hill was reported missing in April after she never returned home one night.
Hill's mother spoke with NewsChannel 4 one week after she vanished.
“Vivacious, outgoing, never met a stranger,” said Lori Hill in April. “That’s not a kid that’s planning on running away. That’s not a kid that doesn’t want to be with her family. That’s my Annie Jo.”
From the moment Hill disappeared, her mother knew the teen had not simply run away.
"They have so many kids that decide they're better off away from home and leave, but Anne was not one of those," said Lori Hill.
For several agonizing months, Anne's fate remained a mystery.
Friends and family held several candlelight vigils, desperate for answers.
Last month, private investigators even drained a pond in Edmond looking for the missing teen.
Despite the search, police say Anne is presumed to be dead.
Now, investigators are getting a little help from the alleged suspects.
Court documents explain how one of the alleged suspects confessed to the murder.
Prosecutors now believe Anne was choked to death inside an apartment complex near downtown Edmond.
The break in the case came when Thomas turned herself into police and confessed to taking part in the crime.
"Thomas came down to police headquarters, was interviewed and was arrested for first-degree murder," said Sgt. Jennifer Wardlow, with the Oklahoma City Police Department.
According to court records, Thomas told police Chadd Raymond "attacked Anne and strangled her until she died."
Initially, the two suspects told police that Hill came to the apartment "trying to purchase drugs" and added that "Anne watched a movie with them before she left."
Thomas now allegedly admits she "helped Raymond dispose of Anne's body."
Calls to Anne's mother now go straight to a recorded message meant for Anne.
"Annie, I hope that's you. I love you. I miss you. We all want you home," says the voicemail.
Edmond Public Schools issued the following statement after learning that a current and former student were arrested in connection with Hill's disappearance.
