The Weekly Beat #1

This week on the beat: the rulings, solved cases and tools that matter to the people who work the case. Each item links to the original reporting.

Case Law

Fake AI-generated images are more convincing than ever. Are courts and police ready?

After a fake AI-generated snake photo set off a Santa Ana police alert, the Orange County Register looks at whether police and courts can tell synthetic images from real ones. One example: an Arizona court threw out a sentence after a victim's family played an AI-generated video of him during the proceedings. (Orange County Register, Oct 16)

Why it matters: Authenticity of photos and video can no longer be assumed. Record provenance from the start: the source device, the original file, and the chain of custody.

Cold Cases

How lost police evidence derailed a historic P.E.I. cold case murder prosecution

Prosecutors in Prince Edward Island withdrew all charges against Todd Joseph Gallant in the 1988 killing of teacher Byron Carr after police lost most of the critical physical evidence, including the towel and knife. Genetic genealogy had led to his 2024 arrest. The Crown also cited gaps in how the remaining evidence was identified and tracked. (CP24, Oct 17)

Why it matters: Genetic genealogy can find a suspect decades later only if the evidence survives. This is the case for auditing cold-case property now, before the break comes.

Chicago police find killer in 65-year-old cold case murder of 8-year-old girl: one of their own

Chicago police identified Thomas McInerney Jr., a 24-year-old patrol officer at the time, as the killer of 8-year-old Gloria Kowalewicz in 1960. FBI genetic genealogy work in 2024 pointed to him from DNA on her clothing, and his fingerprints from his 1959 police application matched a print from her purse strap. He died in 2006. (NBC News, Oct 12)

Why it matters: Old applicant and employment fingerprint cards can confirm a genealogy lead. The evidence lasted 65 years because it was preserved.

Technique

How retired detectives can help police agencies solve cold case homicides

Retired Ohio police chief Scott Reinbolt describes a Richland County unsolved homicide unit that started on a $25,000 budget with part-time retired detectives. Between 2000 and 2006 it solved three homicides and found an infant death that had been misclassified. (Police1, Oct 14)

Why it matters: A small, cheap model for cold case work: pay the retirees who want to work, get the prosecutor and union on board early, and set a clear chain of command.

Tools

Survey: Daily AI use nearly triples among first responders

A survey of 1,035 first responders by Lexipol Media Group for Verizon Frontline found about 32% use AI daily in 2026, up from about 11% in 2025. Unreliable networks (66%) and budgets (61%) topped their concerns. (GovTech Public Safety, Oct 16)

Why it matters: Use is spreading faster than policy in most agencies. If your people use AI tools, you need rules for what they can put into them.

Criminal justice is deploying AI faster than the rules around it

Former Texas Supreme Court Chief Justice Nathan Hecht, who chairs the Council on Criminal Justice's AI task force, proposes a staged review before an agency adopts an AI tool: assess the agency's capacity, weigh benefits against risks to due process and privacy, approve by risk level, and keep monitoring as the tool changes. (GovTech Public Safety, Oct 9)

Why it matters: A practical checklist to use before buying or deploying any AI tool for investigations.
