Doua Yang

On the evening of April 1, 2013, Doua Yang, a 50-year-old Asian man from Vadnais Heights, Minnesota, came home from work, had a shower, and spent some time on Facebook. His family told police he left the house later that night, though they did not know where he was going. It was the last time they saw him alive. His departure into the night ended in a remote, secluded cul-de-sac where his life was violently taken, leaving behind a case that continues to puzzle investigators more than a decade later.

Around 9:40 p.m., deputies from the Anoka County Sheriff's Office were dispatched to the Carlos Avery State Wildlife Management Area in Columbus, a sprawling expanse of wooded terrain. There, off Camp 3 Road, they found Mr. Yang’s body lying next to his car. He had been shot multiple times. The scene immediately presented a contradiction for investigators. Despite the brutal nature of the homicide, robbery was clearly not the motive. Mr. Yang’s car keys were with him, and he had more than $700 in cash in his pockets, all untouched. This suggested a more personal or targeted motive, sending detectives down a path that would lead deep into a digital world of secret messages.

Detectives began to reconstruct Mr. Yang’s final hours, focusing on his activity before he left home. A search warrant for his Facebook account revealed he had been exchanging romantic messages with another user, professing his love and making plans to meet. The account was traced to a 34-year-old married woman named Nou Zong Lee, who lived in Columbus, less than three miles from where Mr. Yang’s body was discovered. The investigation uncovered that the day after the murder, Ms. Lee's Facebook account was deactivated, and she had removed Mr. Yang and eleven other people from her friends list. Further suspicion was raised when investigators found that two days after the killing, before Mr. Yang's identity had been released to the public, Ms. Lee had searched his name on an ancestry website.

Based on the digital trail, authorities moved forward. In the days following the homicide, Nou Zong Lee and her 42-year-old husband, Teng Vue, were arrested. Ms. Lee was charged with second-degree murder. For a moment, it seemed as though the case was heading toward a resolution. However, the path to justice is rarely straightforward. In January 2014, the Anoka County Attorney's Office made the difficult decision to dismiss the murder charge against Ms. Lee, citing insufficient evidence to prove the case beyond a reasonable doubt. Her husband had been released without charges shortly after his arrest. The assistant county attorney stated, "We clearly understand the impact of this on the victim's family," but explained that prosecutors had an ethical obligation to proceed only if they had a good-faith basis to believe they could prove the charge.

For Mr. Yang's family, the dismissal meant a return to a state of uncertainty and unanswered questions. Each passing anniversary of his death is a painful reminder that the person responsible has never been held accountable. The remote location of the crime, within the thousands of acres of the Carlos Avery Wildlife Management Area, has been a significant challenge, offering few witnesses and a difficult environment for recovering evidence.

As of April 2026, the murder of Doua Yang remains an active and unresolved investigation, handled by the Anoka County Sheriff's Office Cold Case Homicide Unit. In recent years, the unit has received a significant boost, including a federal grant of approximately $1.15 million in late 2023 to apply modern forensic techniques to unsolved cases. Investigators are hopeful that advancements in ballistic analysis and DNA testing may yet yield new clues from the evidence collected in 2013. They continue to appeal to the public for information, stressing that even a small, seemingly insignificant detail could be the key to breaking the case open.

The Anoka County Sheriff’s Office urges anyone with information regarding the death of Doua Yang to contact their cold case unit. Tips can be sent via email to [email protected].
