“Rainey Street Ripper”: An Analysis
SEP 2025
The theory that a serial killer is drowning men from Austin’s Rainey Street District has been advanced by social and mainstream media for over two years now. Much of this coverage has criticized the failure of authorities to recognize the threat of a violent offender. But while police must properly respond to the risk of a predator, it is also important they not waste limited resources pursuing a criminal who does not exist. In response to these claims, the Center for Geospatial Intelligence and Investigation, working in cooperation with the Austin Police Department, conducted an evidence-based and scientific study of the data, for the purpose of understanding the nature and cause of these incidents and any possible connection to a serial killer. The project was completely independent and a commitment was made to publicly release the results of the analysis.READ THE REPORT -
