Who Is the Cornell Chopper?


For twenty years, a predator has haunted the halls of Cornell University in Ithaca, New York. He has no confirmed face, no confirmed name, no confirmed motive — only a body count that grows year by year while local law enforcement stumbles in the dark.

His method is as gruesome as it is calculated. Victims — predominantly Asian pre-med students — are abducted without a trace and discovered months later, dismembered, in closets, storage rooms, and utility spaces across campus. By the time they are found, the trail has long gone cold.

This website was built by the families of his victims. We are mothers and fathers, sisters and brothers, friends and classmates who have lost someone we loved. We refuse to be silent. We refuse to accept the failures of the Ithaca Police Department. We demand justice, and we will not stop until the Cornell Chopper is behind bars.

Current Theories — Identity of the Chopper

  • A physician or faculty member with access inside Cornell's medical program
  • Low-level university staff with knowledge of infrequently-accessed locations
  • A local Ithaca resident with no university affiliation — a "townie who has gone bad"

Where Bodies Have Been Found


The map below shows confirmed discovery sites on and around the Cornell University campus. Each marker represents a location where human remains were discovered — often months after the victim went missing.

The Victims


These are not statistics. These were real people — brilliant, ambitious young scholars with their entire lives ahead of them. Profiles below are contributed by their families. 33 total victims. More profiles being added.

🕯
Wei Chen
Age 23  |  Pre-Med  |  Guangzhou, China
Wei came to Cornell on a full scholarship, the first in his family to study abroad. His mother says he called home every Sunday without fail. He wanted to become a cardiologist and return to serve his home province. He never called on a Sunday again after October 14th.
Found: March 2, following year — Olin Library, sub-basement storage
🕯
Jennifer Park
Age 21  |  Pre-Med  |  Fort Lee, NJ
Jennifer was the kind of student who stayed late to help other people understand the material. Her study group still holds a candle vigil every year on the night she disappeared. She was three semesters from graduating. Her parents have not returned to work.
Found: February 18 — Weill Hall utility closet, 3rd floor
🕯
Ming-Hua Liu
Age 24  |  Pre-Med  |  Taipei, Taiwan
Ming-Hua's father flew from Taipei three times trying to get answers from the Ithaca PD. Each time he was sent away with nothing. Ming-Hua had already been accepted to medical school. His acceptance letter arrived six days after he disappeared.
Found: April 7 — Bradfield Hall, locked storage room B-12
🕯
David Zhang
Age 22  |  Pre-Med  |  Shanghai, China
David was funny. Everyone says that first. He did impressions of his professors that had his whole dorm in tears. His roommate still keeps his half of the room exactly as David left it. He was studying for his MCATs the week he disappeared.
Found: January 29 — Baker Laboratory, basement equipment room
🕯
Yuki Tanaka
Age 21  |  Pre-Med  |  Tokyo, Japan
Yuki's English was still a work in progress, but her lab scores were always among the highest in the class. She was shy in lectures but relentless in the lab. Her advisor called her one of the most naturally gifted students he had ever taught. She was reported missing on a Tuesday.
Found: June 3 — Mann Library, archive level 2, behind shelving unit
🕯
Kevin Huang
Age 20  |  Pre-Med  |  Flushing, NY
Kevin was a sophomore. He was 20 years old. He had only been at Cornell for a year and a half. His little sister started college this fall and their parents refused to let her go out of state. Kevin used to make her playlists. She still listens to them.
Found: August 11 — Statler Hall, linen storage, sub-level
🕯
Sophia Wu
Age 22  |  Biochemistry  |  San Jose, CA
Sophia was not pre-med — she was biochem, one of only a handful of non-pre-med victims. Her lab partner of three years gave a statement to the press that went viral. She said, "Sophia was the reason I didn't drop out sophomore year. And now she's gone. And nobody is doing anything."
Found: November 20 — Barton Hall, maintenance storage room 4
🕯
Patricia Delvecchio
Age 57  |  Local Resident  |  Ithaca, NY
Pat worked the morning shift at Shortstop Deli on West State Street for eleven years. She knew everyone's order. She called every regular "hon." She was not a student. She was not pre-med. She was a 57-year-old woman who made good coffee and remembered your name, and the Cornell Chopper took her too. Her daughter said at the vigil: "My mom had nothing to do with any of this. She just lived here." That's all it took.
Found: March 14 — utility room beneath Ithaca Commons pedestrian mall
🕯
Michael Torres
Age 25  |  Graduate — Chemistry  |  Albuquerque, NM
Michael was one of the few non-Asian victims, and his case drew extra scrutiny — some saw it as evidence the Chopper was evolving, expanding his targets. His dissertation was 80% complete. His advisor submitted it posthumously to the university. It was awarded honors.
Found: May 14 — Upson Hall, server room closet, behind cable management panel

Case Timeline


2004
The First Victim
The first confirmed victim, a 23-year-old pre-med student from Guangdong Province, goes missing in late October. Her remains are discovered the following April in a storage room. Ithaca PD opens an investigation. No leads emerge.
2004 – 2016
The Killing Years
Over the next twelve years, 28 more victims are claimed. The pattern is unmistakable — Asian pre-med students, disappearing without a trace, found months later in obscure corners of campus. Despite the escalating body count, Ithaca PD treats each case as an isolated incident for years. No task force is formed. The community seethes.
2017
Detective Weinman Arrives
Detective Weinman relocates from Albany, NY to Ithaca, joining the Ithaca Police Department in search of a fresh start and what he described to colleagues as "a bright new chapter." The Cornell Chopper case lands on his desk within weeks. He reportedly told a colleague: "This one looks straightforward." It was not straightforward.
2018
The Investigation Stalls
Despite early optimism, every lead followed by Detective Weinman ends in a dead end. Witnesses recant. Physical evidence is inconclusive. A promising suspect — a maintenance worker with building access — is cleared after his alibi is verified. Families begin calling the precinct daily. Weinman stops taking their calls.
2020
60 Minutes Covers the Case
The Cornell Chopper case is featured on 60 Minutes. The segment airs nationally and draws international attention. Weinman declines to appear on camera. The Chief of Ithaca PD gives a brief statement that is widely mocked. Within days, calls to the tip line increase by 4,000%. None of the tips lead anywhere.
2021
Chinese Embassy Issues Formal Statement
The Chinese Embassy in Washington D.C. releases a formal statement declaring that it will no longer facilitate student visa placements at Cornell University, citing an "unacceptable risk environment." The statement directly names Detective Weinman and accuses him of "sitting on his ass while the blood of Chinese students stains the floor of Cornell University."
2022
The Medical College Raids
In a desperate escalation, Detective Weinman leads Ithaca PD officers in a sweep of Cornell's medical college offices, arresting faculty, advisors, and administrative staff indiscriminately. All are released within 72 hours. No charges are filed. The university threatens legal action. Weinman is placed on administrative review. No disciplinary action is taken.
2023
The Stop the Chopper Movement Forms
Following years of police failure, families of victims and community members form the Stop the Chopper movement — a grassroots vigilante coalition committed to doing what law enforcement has failed to do. Ithaca PD, stretched thin and demoralized, struggles to contain the movement. The chant echoes across campus: "STOP THE CHOPPER. STOP THE CHOPPER."
Present Day
He Is Still Out There
The Cornell Chopper has not been caught. Detective Weinman remains on the case. There have been no arrests. No confirmed suspects. No justice. The 33rd confirmed victim was found eight months ago. There may be more we do not yet know about. This website exists because someone has to do something.

The Weinman Problem


Detective Weinman: A Record of Failure

We want to be clear: we do not believe Detective Weinman is a bad person. We believe he is catastrophically, dangerously, irredeemably bad at his job. There is a difference. One of them has a body count.

0 Arrests in 7 years
0 Confirmed suspects
33 Victims on his watch
Excuses made

"My son's body was in a closet for four months. Four months. And Detective Weinman couldn't find him. He was in a closet. At a university. That Weinman works at. Do you understand what I am telling you?"

— Father of victim David Zhang, statement to press, 2019

"He came to the vigil. He stood there with a coffee. He didn't say a single word to any of us. He just stood there with his coffee and then he left. That is the man who is supposed to catch the person who killed my daughter."

— Mother of victim Jennifer Park, interview, 2020

"What did you think being a detective in Ithaca would be easy? You city slicker detective! We need results! Phones are ringing off the hook, families are on the line, and you have nothing — NOTHING — to show for seven years of work! What the hell did we even bring you here for?!"

— Chief of Ithaca PD, recorded precinct confrontation with Det. Weinman, 2022 (obtained via FOIA request)

We have submitted four FOIA requests to Ithaca PD regarding the status of the investigation. Three have gone unanswered. One was returned stamped "NO RESPONSIVE DOCUMENTS." We have been told there are over 800 pages of case files. We are still waiting.

In 2022, Detective Weinman authorized the arrest of 14 faculty and staff members of Cornell's medical college program with no probable cause. All 14 were released. Zero charges were filed. When asked to comment, Detective Weinman said, and we quote: "We are pursuing all available avenues."

Seven years. Thirty-three victims. Zero arrests. We are done waiting for Detective Weinman to figure it out.

The World Is Watching


Official Statement — Embassy of the People's Republic of China, Washington D.C.

"The Embassy of the People's Republic of China views the ongoing situation at Cornell University in Ithaca, New York with the utmost gravity and alarm. The systematic targeting of Chinese nationals studying at this institution, combined with the complete and demonstrable failure of local law enforcement — and Detective Weinman in particular — to arrest or even identify any suspect after two decades of murders, has led us to the unavoidable conclusion that Cornell University represents a dangerous environment for Chinese students. Effective immediately, the Embassy will not facilitate student visa placements at Cornell University. We expect the American authorities to treat the lives of Chinese students with the same urgency they would afford any other victim. They have not done so. We are watching."

The Chinese Embassy's statement was followed by expressions of concern from student organizations in South Korea, Japan, and Taiwan. Cornell's international enrollment has declined 34% over the past three years. University administration has declined to comment on whether they believe this decline is connected to the Chopper case.

The case was featured on 60 Minutes in 2020. The segment was watched by an estimated 12 million viewers. The Ithaca PD tip line received over 4,000 calls in the 48 hours following broadcast. Not one has led to an arrest.
