DENVER (KDVR) — Thursday marks five years since Maggie Long was found dead in her home. To this day, her murder remains unsolved.
In fact, there are hundreds of unsolved homicide cases, long-term missing person cases, and unidentified remains cases in our state where at least three years have passed since the crime happened.
The Colorado cold case task force created a list of those cases dating back to 1970. The Problem Solvers are working to highlight cold cases in our state.
Here are 10 of the cases we have highlighted this year:
Maggie Long
On Dec. 1, 2017, 17-year-old Maggie Long was found dead in her Bailey home after it was set on fire. The fire was declared an arson and Long’s death was ruled a homicide.
Many are still desperately searching for answers.
The incident started around 7 p.m. when deputies with the Park County Sheriff’s Office were called to a house fire at 3763 County Road 43 in Bailey. According to a 911 call, people were reportedly inside the home causing damage.
The sheriff’s office said a man was on the property. After the fire was put out, Long’s remains were discovered by firefighters.
Days later, the El Paso County Coroner’s Office ruled her death a homicide.
Investigators said that the scene showed that a physical altercation took place between Long and assailants before the fire started.
The suspects stole a Beretta handgun, an AK-47-style rifle, 2,000 rounds of ammunition, a green safe, and jade figurines, the sheriff’s office said.
The FBI released sketches for three possible suspects in the investigation:
On May 18, 2021, the FBI announced it is investigation Long’s death as a hate crime.
Investigators said whoever killed Long has either told someone or will tell someone. The truth, they say, will surface.
Police are asking anyone with information to contact the FBI or the Park County Sheriff’s Office at 303-239-4243.
JonBenét Ramsey
It has been 25 years since JonBenét Ramsey was found dead. Her murder is considered by many to be one of the most notorious cold cases.
The 6-year-old was found dead in the basement of her Boulder home on Dec. 26, 1996 after her family reportedly found a ransom note inside the home. An autopsy revealed Ramsey was strangled to death.
As of Dec. 2021, the Boulder Police Department said they processed more than 1,500 pieces of evidence related to the murder of Ramsey.
At that time, the Boulder Police Department said “it was actively reviewing genetic DNA testing processes to see if those can be applied to this case moving forward.” BPD said nearly 1,000 DNA samples have been analyzed.
In 2019, Burke Ramsey, the brother of JonBenét, reached an undisclosed settlement in a $750 million lawsuit against CBS. The lawsuit said that Burke Ramsey’s reputation was ruined after a television series suggested he killed JonBenét.
In 2008, then-Boulder County District Attorney Mary Lacy wrote a letter to John Ramsey, JonBenét’s dad, saying new DNA evidence had cleared him, his wife and son. She formally apologized for the cloud of suspicion the Ramsey’s lived under for years.
“We believe at this point it is unlikely there will ever be a prosecution,” Boulder police said in 2008
Ramsey’s mom, Patsy, died of ovarian cancer in 2006.
