 New Chief Data Officer Bobby Zipp
I had a supervisor at the Justice Department who, borrowing from his military background, used to say, “If you want to improve something, measure it.”
From the beginning of my administration, I’ve made it clear: Data is essential to building a more effective and responsive District Attorney’s Office. That’s both Internally, with smart use of metrics to measure and improve performance and efficiency; and Externally, to make the work of the justice system transparent and understandable to the public. That’s why, shortly after taking office, I created the role of Chief Data Officer.
I’m proud to welcome Robert ‘Bobby’ Zipp as our new Chief Data Officer. Bobby has for years now been working in the data shop at the Manhattan DA’s office. He brings a useful mix of experience in data science, AI, and criminal justice technology. He understands prosecution, reform, and how data can inform both. This will be instrumental in helping us make faster, smarter, and more accountable decisions.
As we move forward, Bobby will lead efforts to modernize our systems; identify key areas for innovation; convey accessible data to the public; and strengthen coordination with our partners in law enforcement and the courts.
Working together, we can use data as a real-time tool to improve safety, efficiency, and trust.

Man Incarcerated for Probation Violation, Faces Shooting Charges: On July 9, 2025, Desmond Humphrey appeared in court for a Violation of Probation hearing. Assistant District Attorney Skyler Montgomery successfully argued the case, leading Judge Gilbert to find that Humphrey had violated the terms of his probation. The judge ordered Humphrey to serve the remaining 11 months of his probation in jail.
The probation stemmed from a prior conviction for Domestic Assault. While serving that sentence, Humphrey was rearrested in connection with an April 11 shooting involving a different victim.
The shooting victim survived multiple gunshot wounds to her back, stomach, and wrist. She appeared in court and testified about the April 11 incident. Prosecutors confirmed that Humphrey will face additional charges related to that shooting, pending a Grand Jury indictment.
Assistant District Attorney Skyler Montgomery handled the case.
Memphis Man Held on $125,000 Bond in Criminal Attempt Case: Defendant Fabian Gonzalez appeared in court on Monday for a preliminary hearing on a charge of Criminal Attempt–Second Degree Murder. On Tuesday, after the State submitted a written memorandum of law and presented oral argument, General Sessions Court Judge Greg Gilbert found probable cause. Gonzalez will remain in custody on a $125,000 bond.
The charge stems from an incident where Gonzalez allegedly fired multiple shots at his intimate partner as she ran away in fear. The victim testified that the bullets hit the ground so close to her feet that bits of concrete flew up. She also told the court that Gonzalez had assaulted her in the past.
Assistant District Attorney Annika Rush handled the hearing.
Memphis Man Faces Grand Jury After Preliminary Hearing: On Wednesday, July 2, Raffael Newman appeared in court for a preliminary hearing on charges of second-degree murder and theft of a firearm valued under $2,500. After hearing testimony from five witnesses, the judge found probable cause on both charges and sent the case to a grand jury. Newman remains in custody on a $250,000 bond.
Police say Newman, a convicted felon, shot and killed a man after an argument on the night of May 3, 2025. When officers arrived at the scene, they learned Newman had already turned himself in at the Shelby County Jail at 201 Poplar.
Officers say Newman admitted to the shooting before they took him into custody and charged him.
