Male, 49, Maataua Kalapu Manogiamanu left home on the morning of November 19, 2020, driving west along Anchorage's Dimond Boulevard in a Chevrolet Tahoe. What at first looked like a routine traffic collision at the Minnesota Drive overpass quickly unraveled into something darker. Officers who responded found Manogiamanu, a 49-year-old male, dead behind the wheel with injuries that did not fit the profile of a crash.
Surveillance footage and a closer examination of his body pointed to gunfire, not guardrails, as the cause of his last moments. The Tahoe had careened across lanes and slammed into a light pole only after the driver had been struck, a desperate vehicle carrying a wounded man to a violent stop.
Detectives pieced together the route and the encounter: two vehicles pacing each other from the intersection of Arctic Boulevard and West Dimond Boulevard. From a white Toyota Tundra, shots erupted at close range—first along Dimond between Arctic and Minnesota, then again, after Manogiamanu pulled over near Minnesota and Dimond, where another volley ripped into the Tahoe. One blast pierced his jugular. The blue SUV lurched forward, driver likely already unconscious, and smashed into the streetlight. What began as a morning commute had become a killing carried out on public roads, measured later in feet and seconds on traffic cameras and skid marks.
Within a day, the investigation identified a suspect and shifted from accident reconstruction to homicide. Officers located and arrested 45-year-old Patrick Leu Tauanuu, questioned him, and booked him into jail on charges including first- and second-degree murder. Detectives concluded the incident was not random; the two men knew each other, and the confrontation was born of a domestic dispute. The homicide unit took the case, building it from grainy footage, scene forensics, and witness accounts into a narrative that would eventually stand in a courtroom.
Four years later, a jury affirmed that narrative. On November 26, 2024, Tauanuu was found guilty of murder in the first and second degree for the shooting death of the 49-year-old male victim at the Dimond Boulevard intersections. In the sentencing that followed, the judge described a killing that “approached a planned event,” noting that Tauanuu had obtained a gun the night before and lay in wait the next morning. On August 1, 2025, the court imposed a 65-year prison sentence, closing the loop on a case that began with sirens at sunrise and a light pole bent from the force of impact.
