On the afternoon of March 10, 2020, police responded to a 911 call from a man reporting his wife was unresponsive in their home on Quarles Road in Maple Grove, Minnesota. When officers arrived just after 4 p.m., they found 40-year-old Yang Liu dead; an autopsy later showed multiple gunshot wounds and her death was ruled a homicide.

Investigators focused on Liu’s husband, John Wiseman, who placed the call and initially did not mention that his wife had been shot. Detectives found no sign of forced entry, recovered $5,000 in cash and a passport hidden inside a television antenna box, and detected gunshot residue on the sleeves of Wiseman’s shirt and on a rag in his car. Witnesses described a volatile marriage marked by fights over money and infidelity; they said Wiseman had opposed dividing assets and had met with an estate planner a month before the killing.

In October 2021 a jury convicted John Wiseman of intentional second-degree murder; in December 2021 he was sentenced to 30 years in prison. Did anyone in the Maple Grove area know the couple or notice tensions in their marriage before March 2020?
