About Mark Barcia's Case

Case number: 2020 CF 000010 NC

 

Uniform Case Number: 582020CF000010XXXANC

​

Mark Barcia was involved in a high-profile criminal case in Sarasota County stemming from a fatal New Year’s Eve crash in North Port, Florida.

According to North Port Police, on December 31, 2019, Barcia was accused of driving a Ford F-250 pickup truck when it collided with a Toyota Camry that was operating as an Uber vehicle near Toledo Blade Boulevard and Woodhaven Drive. One passenger in the Uber, identified as David Flick, was killed. The Uber driver and another passenger suffered serious injuries. Arresting Officer Aaron Nick, alongside Sgt. Tony Donohew alleged that Barcia had been the one driving and was drinking before the crash. They then arrested him on charges including DUI manslaughter and multiple DUI-related injury counts.

​

There was another occupant in the Ford F-250, identified as Michael Lauff. Michael Lauff was never properly investigated by North Port Police despite also being involved in the crash. During Mark Barcia's trial, Michael Lauff was given a Letter of Immunity the night after jury selection to ensure that he would testify on behalf of the state against Mark Barcia.

​

This Letter of Immunity was never presented or announced to the jury involved in the trial due to the attorney's Kerry Mack of the Mack Law Firm, and Annemarie Rizzo's of The Law Place decision. This is a Due Process Violation and a Brady Violation to Mark Barcia's Civil Rights, caused by William Stuart Greiner, who was the lead prosecutor for this case in the State Attorney's Office in the 12th Judicial Circuit. The letter of Immunity references that a statue of limitation has been reached, however, there is not such thing as a statue of limitations on any felony case resulting in a death.

​

There are many inconsistencies in this case, including contradicting affidavits, testimony from FDLE personnel with discrepancies from email threads, and crash reconstruction slideshows that represent the odds of Mark Barcia being the passenger of the vehicle to be more likely.

​

As of May 26th, 2026, Mark Barcia has been sentenced by Judge Charles E. Roberts to 18 years of Prison along with 4 years of Probation following his sentence. Mark Barcia is currently Disabled with a multitude of medical conditions such as cervical stenosis, chronic nerve pain, and more. Sarasota County jail currently has possession of Mark Barcia and cannot properly accommodate for his medical conditions which violates Mr. Barcia's 8th Amendment, as well as Title II of the Americans with Disabilities Act.

​

At this time we are seeking further investigation on the accuracy and credibility of all personnel involved in Mark Barcia's case, involving North Port Police Department, the 12th Judicial Circuit, and the State Attorneys Office in Sarasota County.

North Port Police Department & 12th Judicial Circuit State Attorney's Office Credibility Concern

False Testimony by Police or Prosecutors

Napue v. Illinois

  • The Supreme Court held that a conviction violates due process when the prosecution knowingly uses false testimony or allows false testimony to go uncorrected.

  • Even if the false testimony concerns only part of the case, a new trial may be required if it could have affected the jury’s verdict.

Giglio v. United States

  • Expanded Napue.

  • Prosecutors must disclose information that could impeach the credibility of a government witness, including police officers.

  • If an officer has a history of dishonesty, that information can be important to the defense.

​

Suppression of Favorable Evidence

Brady v. Maryland

  • Prosecutors must disclose material evidence favorable to the defendant.

  • This includes exculpatory evidence and evidence that could impeach a key witness.

Kyles v. Whitley

  • Prosecutors are responsible for evidence known to police investigators as well.

  • The government cannot avoid Brady obligations by claiming the prosecutor personally didn’t know.

​

False Statements in Search Warrants

Franks v. Delaware

  • If an officer intentionally or recklessly includes false statements in a warrant affidavit, and those statements were necessary to establish probable cause, the warrant can be invalidated.

  • This case is frequently cited when allegations of police perjury involve search warrants.

​

Police Misconduct Affecting Convictions

Mooney v. Holohan

  • One of the foundational cases holding that convictions obtained through deliberate deception by government officials violate due process.
