An excerpt from the "Anonymous Memo" written by former Dayton police Sgt. Dennis Haller to expose corruption in the department.

After the death of his son in 1979, Dayton Police Detective Sgt. Dennis K. Haller penned the “anonymous memo” that kicked off an investigation into what’s considered the largest police corruption scandal in Dayton history.

The ensuing investigation led to a grand jury in 1985 approving criminal charges against nearly 20 current and former law enforcement officers. The charges ranged from tampering with evidence, dereliction of duty, eavesdropping and interfering with civil rights to perjury and involuntary manslaughter.

Retired Dayton Daily News reporter Wes Hills has kept a copy of the memo for decades. The Dayton Daily News is publishing segments of it as part of our Gem City Gamble project.

Go here for the full story about the memo, including interviews with Haller that the Dayton Daily News agreed not to publish until after his death, which occurred in 2023. The newspaper is also revealing for the first time that Haller was the memo’s author.

Here is the first page of the memo. The Dayton Daily News redacted names because many people referenced in the memo could not be reached for comment.

ABOUT THIS PROJECT:

GEM CITY GAMBLE

A project from the Dayton Daily News

Former Dayton police Detective Dennis Haller’s career spanned a dark time for the Dayton Police Department. Haller was a source for Dayton Daily News reporter Wes Hills, who retired in 2004 after 30 years at the paper, and agreed to share information with Hills on the condition it stay confidential until Haller’s death, which happened in 2023.

Now, we bring you Gem City Gamble, a series that uses Hills’ interviews and notes to shed new light on the largest police corruption scandal in city history and how police wiretapping and a spurned bookie may have contributed to the downfall of baseball legend Pete Rose.
