CNN) -- Authorities have arrested a "possible suspect" in the decade-old JonBenet Ramsey murder investigation, law enforcement sources told CNN on Wednesday.
An investigator with the Boulder County, Colorado, District Attorney's office traveled to Bangkok, Thailand, and is bringing a suspect back to the United States, CNN Denver affiliate KUSA reported.
The suspect was arrested Wednesday morning and has confessed to certain elements of the crime that are unknown to the general public, KUSA reported.
The man already was already held in Bangkok on unrelated sex charges, sources told The Associated Press.
Prosecutors have not confirmed the identity of the suspect, but expect to hold a press conference later today.
JonBenet's beaten and strangled body was found in the basement of the family home in Boulder, Colorado, the day after Christmas in 1996. She was 6.
A grand jury investigation into the death of the child beauty pageant winner ended without charges in 1999.
The investigation focused a spotlight on the child's parents, John and Patsy Ramsey. Patsy Ramsey died in June of ovarian cancer. She was 49.
The Ramseys said an intruder committed the crime, but they remained the subject of suspicion and speculation.
In 2003, a federal judge dismissed a lawsuit against the Ramseys, blaming the police and the FBI for bungling the investigation. The Boulder County District Attorney's Office concurred with the judge's opinion the following month, saying there was little evidence against the couple
The Ramseys left Colorado and had a house in Charlevoix, Michigan, where John Ramsey unsuccessfully ran for office in 2004, and in Atlanta, Georgia
