A former Rohnert Park police officer, Joseph Huffaker, is seeking a new federal trial, arguing that contradictory testimony from a co-defendant undermines the jury's verdict that led to his July conviction and possible 20-year sentence. Huffaker's attorney claims the co-defendant gave "false testimony" regarding allegations Huffaker obstructed a federal investigation.

Why it matters

This case highlights ongoing issues of police misconduct and abuse of power, as well as the challenges of ensuring fair trials and sentencing in complex federal cases involving former law enforcement officers.

The details

Prosecutors allege that Huffaker and a fellow officer, Brendan "Jacy" Tatum, ran a years-long scheme through the Rohnert Park Department of Public Safety drug interdiction team, posing as federal agents during Highway 101 traffic stops and seizing cash and cannabis from drivers. Huffaker was convicted on six counts, including conspiracy to commit extortion and impersonating a federal officer. In one incident, prosecutors said Huffaker joined a traffic stop involving 23 pounds of marijuana and falsely identified himself as an ATF agent before seizing the drugs.

  • Huffaker was convicted by a federal jury in July.
  • Huffaker's sentencing, originally scheduled for October, has been postponed multiple times and is now set for April 15, 2026.
  • Huffaker's co-defendant, Brendan "Jacy" Tatum, pleaded guilty in 2021 to related charges including falsifying records and tax evasion.
