Phoenix lawsuit alleges a facial-recognition lead contributed to a wrongful arrest

Javier Lorenzano Nunez was arrested in October 2024 for the 1998 murder of Sarah Carr after investigators ran the old suspect's MVD photo through facial recognition databases, got 250 possible matches and zeroed in on him — with Phoenix police publicizing the arrest in a press release and a special video. Charges were dismissed without prejudice in August 2025 after forensic evidence, including DNA and fingerprints, excluded him. His lawsuit alleges Phoenix police knew from a 2017 fingerprint analysis that his prints did not match, and ignored a 2007 Puerto Rico lead on the original suspect with the same name, date of birth and social security number. He spent nearly a year in jail. The federal suit against the Phoenix Police Department and the Maricopa County Attorney's Office alleges gross negligence, false arrest, false imprisonment and defamation.

What Happened

Sarah Carr was shot and killed on 9 July 1998 in Phoenix; witnesses identified Gilbert Noel Sanchez Rosado, who fled and was never found. Two decades later investigators ran Rosado's old Arizona MVD photo through facial recognition databases operated by the Arizona Department of Public Safety and the FBI, received 250 possible matches and zeroed in on Lorenzano Nunez. Phoenix police made much of the October 2024 arrest — a press release, a special video, the victim's son Garrett Miller (himself a police officer in Texas) flown in, his handcuffs used in the bust. According to the lawsuit and court records obtained by ABC15, facial recognition 'appears to be the key evidence used to arrest Lorenzano Nunez'. The suit further alleges police ignored a 2007 Puerto Rico Police Department lead reporting a man named Gilbert Noel Sanchez Rosado in custody with the same date of birth and social security number as the suspect, and that Phoenix had obtained Lorenzano Nunez's fingerprints after a 2011 San Diego arrest: the analysis, completed in 2017, excluded him on two latent prints and was inconclusive on two others — seven years before his arrest. The Maricopa County Attorney's Office said the evidence police provided when the case was submitted 'pointed toward Javier Lorenzano-Nunez' and called facial recognition software a 'valuable investigative tool'; charges were dismissed without prejudice in August 2025 because additional evidence put his guilt beyond a reasonable doubt. Miller told FOX 10 the outcome was heart-wrenching but that he believes in the investigators. The Ortega Law Firm first filed a notice of claim (arguing facial recognition merely identified a possible lead), and in July 2026 ABC15 reported the federal lawsuit alleging he was 'arrested without probable cause' and that police and prosecutors 'committed gross negligence, false arrest, false imprisonment, negligent infliction of emotional distress, and defamation'. Phoenix police and the county attorney declined to comment.

Reported harm

Nearly a year wrongfully jailed on a facial-recognition-driven cold-case arrest that police publicized with a video and the victim's son's handcuffs, ending only when DNA and fingerprint evidence excluded him; he now alleges false arrest, false imprisonment and defamation.

How Harm Occurred

A facial-recognition hit among 250 candidates was treated as key arrest evidence instead of a lead; the institutional response — a publicized arrest and year-long detention — collapsed only when forensic evidence excluded him.

Outcome

Ongoing

Charges dismissed without prejudice August 2025; notice of claim filed by the Ortega Law Firm; federal lawsuit against the Phoenix Police Department and the Maricopa County Attorney's Office reported 2 July 2026. The 1998 murder remains unsolved.

What remains unknown

  • The specific facial-recognition vendor/system is not named in the inspected reporting.
  • Details from ABC15's earlier 'About Face' investigation (including any grand-jury or foreign-custody particulars) were not re-verified in this pass and are not claimed.
  • The federal suit's filing date and docket number are not stated in the inspected sources (reported as filed by 2 July 2026).
  • Whether he was held continuously from October 2024 to August 2025 ('nearly a year in jail' per ABC15) is reported without a custody breakdown.
  • The 1998 murder of Sarah Carr remains unsolved; the 2007 Puerto Rico lead's current status is unknown.

What the evidence supports

AI involvement: supported. The lawsuit and court records, per ABC15, make facial recognition 'the key evidence used to arrest'; the county attorney calls it a 'valuable investigative tool' while the notice of claim says it merely identified a possible lead. The specific vendor system is not named in the inspected reporting.

5 claims: 1 documented, 2 corroborated, 2 reported. What the statuses mean

Corroborated Lorenzano Nunez was arrested in October 2024 for the 1998 murder of Sarah Carr after investigators ran the old suspect's MVD photo through facial recognition databases (Arizona DPS and FBI), received 250 possible matches and zeroed in on him; Phoenix police publicized the arrest with a press release and a special video featuring the victim's son.

Causal attribution. The arrest and the FR role are carried by both chains; the lawsuit's characterization of FR as 'the key evidence' is attributed to the filing and court records.

Tennessee grandmother Angela Lipps jailed five months on an AI facial-recognition misidentification; charges dismissed after bank records placed her 1,200 miles away

On 14 July 2025, U.S. Marshals arrested Angela Lipps, a 50-year-old Tennessee grandmother, at gunpoint at her home while she was babysitting four children, on a nationwide-extradition North Dakota warrant: West Fargo police's AI facial-recognition technology had tied her to bank-fraud surveillance of a woman using a fake U.S. Army military ID to withdraw tens of thousands of dollars. She fought extradition for about three months in a Tennessee jail, was booked into Cass County, North Dakota on 30 October 2025 on four counts of unauthorized use of personal identifying information and four counts of theft, and was released on 24 December after her bank records showed her more than 1,200 miles away in Tennessee; charges were dismissed without prejudice. Fargo's police chief acknowledged 'incorrect assumptions' linked to the AI identification; an email obtained by KVLY shows six Fargo detectives were notified of her arrest in July, nearly five months before the department says it knew she was in custody. She lost her home, her car and her dog; her attorneys are pursuing potential civil-rights claims, with no lawsuit filed as of 31 March 2026. On 15 September 2026 she filed a $10 million federal civil-rights suit in the District of North Dakota against the City of Fargo and the detective, alleging he relied on a flawed facial-recognition match and ignored exculpatory evidence.

Florida: 93% facial-recognition hit led to Robert Dillon's arrest as an attempted child abductor; charges dropped, ACLU suit filed

In August 2024, Robert Dillon, a 52-year-old self-employed commercial crabber from the Fort Myers area, was arrested at his San Carlos Park home on a third-degree felony warrant for the attempted luring of a child at a Jacksonville Beach McDonald's in November 2023 — a crime he had no part in. The warrant rested on a 93%-confidence result from FACES, the Face Analysis Comparison and Examination System maintained by the Pinellas County Sheriff's Office, run against low-resolution cell-phone photos of a surveillance screen, plus a restaurant employee's photo-lineup identification. Dillon spent a night in jail and bonded out against his truck's title; prosecutors dropped the charges in October 2024 after work-alibi evidence, but it took about a year to expunge the arrest and remove his mugshot. In June 2026 the ACLU filed a federal lawsuit (M.D. Fla.) against Jacksonville Beach, the Jacksonville sheriff and the Pinellas County Sheriff's Office, calling Dillon one of at least 14 known wrongful arrests from police reliance on facial recognition since 2019.

Reno casino's facial recognition wrongly matched a patron to a barred man and police jailed him for about eleven hours, his federal lawsuit alleges

Jason Killinger, a UPS truck driver, alleges in a federal civil-rights complaint filed in July 2025 that on 17 September 2023 the Peppermill Casino in Reno reported to police that its AI facial recognition software had identified him as a man barred from the casino months earlier. According to the complaint, casino security handcuffed him, and the responding Reno police officer, told the system had found a 100 percent match, did not examine his other identification and took him to jail as an unidentified person, where fingerprints confirmed who he was. The complaint says he was handcuffed for about four hours, starting in the casino security office, spent about eleven hours in police and jail custody, and was treated the next day for bruised wrists. According to the complaint, he was then charged with trespassing, and a prosecutor dismissed the charge without prejudice at the bench trial. Casino.org reports that he settled a suit against the casino. In March 2026 the court let him add the City of Reno and a municipal liability claim over facial recognition policies, but refused a new wrongful arrest claim against the officer on qualified immunity grounds. In September 2026 the ACLU, the ACLU of Nevada and the Innocence Project filed a proposed amicus brief supporting him. His September 2026 motion for partial summary judgment says a Reno police detective later concluded that the match was wrong and that he and the barred man were different people, and it cites a declaration by a former casino security officer, who worked there from about October 2024, that the system often alerted at 100 percent on the wrong people; in a declaration reported by Casino.org, the officer said he had never known the system to misidentify anyone. The case is ongoing.

Maryland/Oklahoma: Kimberlee Williams, an Oklahoma woman who says she had never been to Maryland, was arrested in June 2021 and jailed about six months on bank-fraud charges in three Maryland counties after a facial-recognition search by an unknown CrimeDex respondent named her; all charges were dismissed by December 2021 and the ACLU filed complaints in April 2026

According to police and bank records reviewed by the Washington Post, in December 2019 a woman made fraudulent withdrawals at a SunTrust branch in Potomac, Maryland; branches in two other Maryland counties were also defrauded. A bank investigator posted the surveillance photos on CrimeDex, an online network of police and corporate investigators; an unknown respondent ran the image through facial-recognition software and returned Kimberlee Williams's name and photo, and the investigator told Montgomery County police that facial-recognition software had identified her. Police in Montgomery, Prince George's and Anne Arundel counties charged her in 2020 on the investigator's identification and their own visual comparison of photos (two departments also cited her old Oklahoma check-fraud convictions), without reported checks of her whereabouts; Montgomery County police did not disclose the facial-recognition search in the charging application, according to police records reviewed by the Washington Post and the ACLU. On 23 June 2021 she was arrested at the gate of Fort Sill near Lawton, Oklahoma, while accompanying her daughter on a DoorDash delivery, spent about three weeks in an Oklahoma jail, was flown to Maryland, and faced 16 charges including 12 felonies. The counties dismissed the charges one after another, in October and December 2021, after about six months in jail. Her daughter says she was depressed afterwards; the ACLU says the ordeal harmed her mental and physical health. On 14 April 2026 the ACLU and ACLU of Maryland sent complaint letters to the three departments seeking an apology and reforms.
