Police are launching a new investigation into the unsolved murder of JonBenet Ramsey

Police are launching a new investigation into the murder of 6-year-old JonBenet Ramsey in Boulder, Colorado, nearly three decades after she disappeared.

Investigators will consult with a state cold case team as they continue to investigate the 1996 murder of the little girl.

Authorities have received more than 21,000 tips, letters and emails about the case and have traveled to 19 states to speak to more than 1,000 people, but the murder remains unsolved.

“This crime has left a hole in the hearts of many and we will never stop investigating until we find JonBenet’s killer,” Police Chief Maris Herold said in a press release on Wednesday, ahead of the 26th anniversary of JonBenet’s death.

The Colorado Cold Case Review Team is made up of professional investigative, analytical and forensic professionals from across the state.

Police said the team was “another tool to assist further investigations into cold-case homicides.”

JonBenet was found beaten and strangled to death in the basement of her family’s Boulder home on December 26, 1996.

At the time, the only other people known to be in the home were her parents, Patsy and John, and her brother Burke.

Nobody has ever been charged.

Police have often been criticized for their initial handling of investigations, and JonBenet’s father this year showed support for an online petition calling for the governor to step in by hiring an outside agency to run DNA tests.

For years, theories have circulated that JonBenet, who has spent much of her life competing in beauty pageants, was killed by an intruder who broke into her home, or by a member of her family.

Initially, the Ramseys were reluctant to be questioned by the police or to allow their then nine-year-old son to be questioned.
