数十年后破获的悬案：十大最长破案时间（2026年）

After two hung juries in 1964, a third trial 31 years later produced a conviction the state high court upheld 4-2.

Decades after two all-white juries deadlocked in 1964, unsealed state sovereignty files and testimony of the suspect boasting about the rifle shot sealed a conviction 30 years and 8 months later.

30 years, 8 months — two hung juries in 1964, then secret state files showing jury tampering and new witnesses who had heard him boast.

A 47-year wait ended mid-trial in 2021 with a guilty plea after DNA evidence was presented.

Nearly 46 years later, DNA-linked evidence led to a guilty plea on the third day of trial.

A tip from a relative and confessions made to community church members brought a murder conviction 37 years and 8 months after the boy vanished walking to his school bus.

Nearly 38 years — a 6-year-old's walk to the school bus; the break came when a relative, watching news of a basement dig, finally called police about a confession from 1980.

The first trial of a suspect found through genetic genealogy ended in a guilty verdict after 32 years.

Marked the first conviction in history secured via genetic genealogy to go before a trial jury, remaining fully affirmed by the Washington State Supreme Court 32 years later.

Thirty years after an eight-year-old was killed, genealogy helped identify a man already writing taunts to police.

30 years, 8 months — the killer taunted police with DNA-laden notes for decades; a public DNA database gave him a name in July 2018.

A 43-year wait. A 2008 panel threw the verdict out on statute of limitations grounds, and the full court later put it back.

32 years from the earliest victim — and the break wasn't genealogy; it was a witness's memory of a Chevy Avalanche, plus a pizza crust in a Manhattan trash can.
