Main Theme & Purpose

This episode of Criminal, hosted by Phoebe Judge and featuring reporting by Lizzie Peabody (from the Smithsonian’s Side Door podcast), tells the story of Cheol Su Lee—a Korean immigrant wrongfully convicted of murder in 1970s San Francisco.

Key Discussion Points & Insights

1. The Chinatown Murder and a Flawed Investigation

• Background: In 1973, gang leader Yip Yi Tak is killed in San Francisco’s Chinatown, with numerous unsolved murders destabilizing the area and threatening the city’s tourism-driven economy. (01:01–01:46)
• Lack of Community Cooperation: Fear of gang retaliation causes Chinatown’s residents to refuse cooperation with police, leaving only white tourist eyewitnesses. (01:10–01:50)
• Faulty Arrest: Police use mug books of Asian men for witness identification. Tourists identify a young Korean man, Cheol Su Lee, based on fleeting observations from a distance. (01:58–02:16)
• Weak Evidence: Ballistics tests (later proved faulty) and mistaken witness identification lead to Cheol Su Lee being charged, convicted by an all-white jury, and sentenced to life in prison. (02:40–02:51)

Quote:
“They [the police] were only able to get these white tourists who saw the killer for mere seconds from quite a distance away to come down to the station and look through mug books full of photographs of Asian men.”
—Lizzie Peabody (01:50)

2. Personal and Community Reactions

• Personal Ties: Ranko Yamada recalls knowing Cheol Su Lee as “Charles Lee” and doubts his guilt, yet recognizes he’s alone and can’t afford a lawyer. (04:09–04:49)
• Silent Faith: A Chinatown community member assures Ranko that “Chosu didn't do that. We all know that he didn't do that murder,” giving her the first true conviction of his innocence. (05:20)

3. KW Lee: The Journalist Who Wouldn’t Look Away

• KW Lee’s Principles: Informed by his immigrant experience and a career exposing corruption, KW Lee becomes obsessed with Cheol Su Lee’s case, sensing institutional failure and anti-Asian prejudice in the proceedings. (06:24–09:17)
• Immigrant Connection: KW’s empathy is heightened by his shared Korean background with Cheol Su Lee and his understanding of being marginalized by mainstream society. (07:03–08:48)
• Investigative Passion: Despite editorial pushback, KW investigates on his own time, seeking the truth behind the arrest. (09:57–10:23)
• Setting The Record Straight: KW publishes a two-part investigative series that shifts public perception, focusing on Cheol Su Lee’s struggles as an immigrant and the injustice faced in the American justice system. (14:24–16:17)

Quote:
“Thus began the Americanization of Cheol Su Lee with good intentions and benign ignorance, paving the road to a private hell for the bewildered boy from Seoul, Korea.”
—KW Lee (17:05)

4. The Case Unravels: Police Errors and Eyewitness Flaws

• Ballistics and Mug Books: The police’s ballistics match is proven false before trial, but prosecution persists. Eyewitnesses were tourists asked to pick “similar looking” faces from mug books rather than true identification. (22:29–23:59)
• Cross-Racial Identification Issues: None of the eyewitnesses were Asian, introducing proven error into the identification process—research shows misidentification is over 50% more common across races. (26:28–26:30)
• Physical Mismatch: The shooter was described as 5’6–5’10 and clean-shaven; Lee was several inches shorter and had a mustache. (24:22–24:49)
• Suggestive Lineups: Witnesses were essentially guided by police suggestion—a classic illustration of confirmation bias. (25:13–25:50)

Quote:
“You almost can't fault the witnesses. The police slowly, over time, persuade them to believe that the person they have chosen is in fact the one.”
—Ranko Yamada (25:35)

5. Birth of a Pan-Asian Movement

• Activism Sparks: Korean Americans in Northern California and college students rally, sparked by KW Lee’s articles. They begin fundraisers, spread Lee’s story, and form the Free Cheol Su Lee Defense Fund. (27:08–28:57)
• Spillover Effect: Community action expands into a broader Asian American solidarity, incorporating Chinese, Japanese, and other communities, reflecting the legacy of the Civil Rights and Ethnic Studies movements. (29:03–30:12)
• A Song for Justice: Even cultural forms, such as protest songs, are used to unify and amplify the cause. (30:37)

6. Breakthroughs and Overturned Convictions

• Suppression of Key Witness: New investigators (funded by the movement) uncover Stephen Morris, a crucial eyewitness omitted by police and never consulted by Lee’s original defense—his statement exonerates Lee. (31:29–32:37)
• Legal Victory: The previous conviction is vacated on grounds of police misconduct. (32:37)
• Setback and Endurance: Meanwhile, Cheol Su Lee is separately convicted (and sentenced to death row) for the prison yard stabbing, highlighting the stakes and injustice in continuing prosecution despite rising doubts. KW Lee leaves his job to continue supporting Lee, founding a Korean American newspaper. (35:28–36:01)

7. Community, Family, and Redemption

• Support Systems: Letters between KW Lee and Cheol Su Lee show a deep, father-son bond, with KW providing hope and encouragement during Lee’s darkest moments in prison. (36:14–37:10)
• Resilience: Even as Lee awaits his retrial on death row, the community keeps rallying, and their presence proves vital during the new trial. Supporters—young activists and elderly churchgoers alike—fill the courtroom. (37:32–38:13)

8. Exoneration and Impact

• Retrial and Acquittal: The 1982 retrial brings new legal firepower and exposes weaknesses in the prosecution; Lee is acquitted after a single day of jury deliberation. The courtroom erupts in emotional release. (39:32–40:04)

Quote:
“With tears brimming in his eyes after the nine man, three woman jury read the not guilty verdict, Cheol Soo Lee faced his supporters through bulletproof glass partitions of the maximum security facility and told them that his victory was in fact theirs... The audience wept. Even some sheriff's bailiffs showed red rimmed eyes.”
—KW Lee (40:32)

• Life After Prison: Though Lee stays formally convicted for the prison yard death, a plea deal sees him released in 1983 after nearly a decade in prison. His story permanently changes key players—Ranko becomes a lawyer and advocate; KW dedicates his career to mentoring and Asian American journalism. (41:29–43:09)

9. Legacy of KW Lee and Cheol Su Lee

• Mentorship and Memory: KW Lee becomes a mentor for generations of young journalists and a symbol of integrity and compassion. He remains close to Cheol Su Lee until Lee’s unexpected death in 2014. (42:54–43:52)
• Cultural Recovery: Inspired by KW’s anger at society’s collective amnesia, Julie Ha produces a documentary on Lee’s fight for justice. KW passes away in 2025 at age 96, remembered as “the godfather of Asian American journalism.” (44:22–45:02)

Quote:
“I've known many, many brilliant people, people I would consider genius, and KW was one of them. Smart is just smart. But when you couple that with the compassion that he had and his integrity and his feeling for humanity as a whole, that's singular. That's the difference.”
—Ranko Yamada (45:16)

• Epitaph: KW’s essence captured by a former colleague describing him:
  “KW gives a shit… he really gave a shit.”
  —Sojin Kim (46:13)
