The JonBenét Ramsey Case
The JonBenét Ramsey case is one of Colorado’s most widely discussed and debated unsolved mysteries. This case involves a young girl’s tragic death, a complicated investigation, and years of speculation about the killer’s identity.
Details of the Crime
JonBenét Ramsey was a six-year-old girl living in Boulder, Colorado. She was found murdered in the basement of her family’s home after her parents, John and Patsy Ramsey, reported her missing early in the morning on December 26, 1996.
A handwritten ransom note was discovered inside the house. The note demanded $118,000, which matched the exact amount of a recent bonus JonBenét’s father received.
The family found JonBenét’s body several hours after police began searching the home. The cause of death was strangulation and a blow to the head.
She was found with her wrists tied and duct tape over her mouth. These details made the case unusually complex and disturbing.
Investigation and Evidence
The investigation began quickly, but police made mistakes at the crime scene and evidence was compromised. Multiple people, including friends and neighbors, walked around the Ramsey house before police secured the area.
Police collected several pieces of evidence, including the ransom note, fibers, and DNA samples. The ransom note was long and appeared to have been written inside the house, suggesting the killer spent time there.
Forensics found unidentified male DNA on JonBenét’s clothing, which did not match any family member. This DNA discovery added to the mystery and raised new questions about possible intruders.
Over the years, police and outside experts reviewed the case, but disagreements about the evidence slowed progress.
Theories and Suspects
Several theories about the killer’s identity have been discussed. Some believe an intruder entered the home, while others have focused on the Ramsey family.
The Ramsey parents, John and Patsy, were investigated but always denied involvement. They were never officially charged.
Another theory centers on an unknown assailant who might have broken in, but evidence for this idea has not been conclusive.
Main suspects and ideas:
- John and Patsy Ramsey (parents)
- Burke Ramsey (brother)
- An unidentified intruder
Despite years of investigation, no one has been arrested or charged. The case is still discussed whenever unsolved mysteries from Colorado or true crime in Denver are mentioned.

Haunting Unsolved Murders
Colorado has many stories where justice was never served. Families still wait for answers.
These cold cases reveal the challenges of solving crimes, especially when important clues are missing.
The Lynda Avery Mystery
Lynda Avery was a young woman living in Colorado whose murder remains unsolved. In 1975, her body was found in a rural part of the state.
The mysterious circumstances and lack of eyewitnesses made the investigation even harder for police. Detectives followed a few leads and questioned people close to Lynda, but no one was arrested.
Evidence collected at the scene did not provide clear answers. Friends and family remember her as a kind and friendly person who deserved justice.
People in Colorado still talk about the unsolved case, hoping someone might remember something important. The case stays open, and the hope for closure continues.
The Killing of Adolph Coors III
Adolph Coors III, a member of the famous Coors brewing family, was kidnapped and murdered near Morrison, Colorado, in 1960. Investigators found his abandoned car on a bridge, with only small clues left behind.
After a nationwide search, police found his body months later in a remote area. The murder shocked the state and drew wide media attention.
The investigation was complex and involved the FBI, which put pressure on law enforcement to find the killer. Joseph Corbett Jr. was eventually arrested and convicted after escaping from prison.
Questions remain about the full details of the crime and if anyone else was involved. Many people still discuss this tragedy as one of Colorado’s most famous cold cases.
Sing Lee’s Unsolved Homicide
Sing Lee was a respected Chinese businessman in Central City, Colorado, during the late 1800s. He was found murdered in 1880, and the case quickly became one of the earliest and most mysterious unsolved homicides in state history.
Lee ran a laundry business and was well-known in the area. Despite a reward being offered for information, no one came forward with useful evidence.
The investigation struggled because of limited forensic tools in that era and possible racial biases. Community members expressed sadness, but the crime remained unsolved.
Sing Lee’s case is still a reminder of the difficulties faced in historic investigations and the ongoing search for truth in Colorado’s past.
Theodore Coneys and The Denver Spiderman
The story of Theodore Coneys is one of Denver’s most startling and unique tales. The case connects a mysterious murder, a hidden intruder, and the historic neighborhood of Capitol Hill.
A Chilling Intruder
In 1941, Theodore Coneys, a struggling drifter, entered the home of an old friend named Philip Peters. He did this without permission and, when discovered, killed Peters to avoid exposure.
What made this crime so shocking was not just the murder, but what happened next. Instead of fleeing, Coneys hid in a tiny attic space above Peters’ house.
For nine months after the killing, he lived in this dark cavity, sneaking out only to find food when the house seemed empty. Locals and police were baffled by strange noises and missing food.
Some suspected supernatural activity. The story became so strange that Coneys earned the nickname the Denver Spiderman.
When police finally found him, the city was stunned by the idea that someone could remain so well-hidden in a busy neighborhood for so long.
Key details:
- Crime occurred in 1941
- Hidden in attic for nine months
- The case is tied to an unsolved-mystery atmosphere due to delays in his capture
Capitol Hill Connections
Peters’ house was located in Denver’s historic Capitol Hill neighborhood, an area known for its grand old homes and storied past. This location added another layer of fascination and fear to the case.
Neighbors lived so close to an unfolding mystery without realizing it. Capitol Hill became a focus of curiosity as police and journalists tried to piece together what happened.
Residents couldn’t believe that someone could live undetected alongside them in such a well-populated area. This event led to local legends about the old houses possibly hiding more secrets.
The tale of the Denver Spiderman remains one of Capitol Hill’s most bizarre and remembered stories.

Escape and Investigation
After police arrested and charged Bundy for the murder of Caryn Campbell, they held him at the Pitkin County Courthouse in Aspen. In June 1977, he escaped from custody by jumping from a second-story window while left alone for a brief period.
This launched a huge manhunt across western Colorado, with police searching mountain trails, cabins, and rural roads. Bundy broke into cabins to steal clothes and supplies while on the run.
His escape caused panic and frustration for investigators, who struggled to capture him. Bundy was recaptured after eight days, only to escape again later from a jail cell in Glenwood Springs.
These daring escapes stretched police resources thin. They are still remembered as some of the boldest in Colorado’s true crime history.
