Heather Lamperd

On a crisp autumn afternoon in Minneapolis, Heather Lamperd finished her workday and began a journey home that she would never complete. The 26-year-old female was a reliable employee at the Northern States Power Company, located in the city's bustling downtown on Nicollet Mall. On Thursday, November 2, 1989, she left the office around 3:30 p.m., just as she always did. Heather did not own a car and relied on public transportation for her daily commute. Her usual routine involved taking the number 16 bus to her apartment in the Cedar Square East complex, a distinctive high-rise community on the West Bank of the University of Minnesota campus.

That evening, Heather had plans. She was expected for dinner at her grandmother's home, and some coworkers later said they had arranged to meet her at a bar. But as the hours passed, a sense of unease grew. Heather never arrived for dinner with her grandmother, Carolyn Devenport, who became increasingly alarmed by her absence. She never met her friends for a drink. The calls to her apartment went unanswered. The routine of a normal Thursday had been violently broken, leaving only questions and a deepening sense of dread.

The next morning, around 10 a.m. on November 3, the search for Heather came to a tragic end. Her body was discovered approximately 45 miles north of Minneapolis in rural Chisago County. A passerby found her in the cold, shallow water of the Sunrise River, just off State Highway 95, about four and a half miles east of the town of North Branch. Investigators believe her body was thrown into the river from a small highway bridge spanning the water. An autopsy revealed the brutal nature of her death: she had been beaten and strangled. The petite woman, who stood 5-foot-2 with reddish-blond hair and weighed only 110 pounds, had just $1.14 in her pocket.

The investigation was launched immediately, jointly handled by the Chisago County Sheriff's Office and the Minnesota Bureau of Criminal Apprehension (BCA). Detectives faced a difficult case from the start. With no vehicle of her own, police theorized that Heather must have been picked up by someone after leaving work, but they did not know if she accepted a ride from an acquaintance or was abducted by a stranger. The location where she was killed remains a mystery, as does the motive for the vicious attack. In the initial days of the investigation, a detective told the Star Tribune they were not close to an arrest.

Decades have passed, but the murder of Heather Lamperd has never been forgotten by law enforcement. In 2008, the case was officially assigned to Chisago County's homicide unit and the BCA's cold case team for a fresh review. Investigators remain hopeful that with the passage of time, someone with crucial information will finally come forward. The key to solving the case could be a small, seemingly insignificant detail remembered by a friend, a former coworker, or someone who saw something unusual along the bus route or the highways leading north from Minneapolis on that November evening.

As of November 2026, Heather Lamperd's case remains unsolved, a lingering source of pain and unanswered questions. Investigators are still actively seeking new leads that could bring them closer to finding justice for the young woman whose life was cut short so senselessly. The community of North Branch, a small city known for its access to the St. Croix River Valley, remains the final resting place for a woman who belonged to the vibrant heart of Minneapolis.

Crime Stoppers of Minnesota offers a reward of up to $1,000 for information that leads to an arrest in the case.
