Jonathan Rinderknecht, the suspect facing federal arson charges for allegedly starting the deadly Palisades fire of January 2025, appeared at an evidentiary hearing on Monday, where the judge overseeing the case deliberated the admissibility of certain evidence and witness testimony.Rinderknecht, who has pleaded not guilty to setting off one of the most destructive and lethal wildfires in Los Angeles history, is scheduled to stand trial in June.Judge Anne Hwang, an appointee of former President Joe Biden, heard a series of motions on Monday that would decide, depending on which way she rules in the following days, what exhibits are admissible at next month’s trial and who is allowed to testify.

Attorneys for Rinderknecht requested that Hwang permit the defense team to introduce as evidence a previous case involving ATF Special Agent Matthew Beals, one of the investigators in the current case against Rinderknecht.

Beals was the lead ATF agent in the arson investigation of Navy Seaman Ryan Mays, who was accused of igniting a 2020 fire aboard the USS Bonhomme Richard in San Diego, California. A military court acquitted Mays of all charges after a two-week trial.

“This prior investigation, prosecution, and acquittal bear extraordinary and unmistakable similarities to the investigation Agent Beals has conducted against Mr. Rinderknecht in the present case and, critically, reveals a pattern, motive, and systematic bias that is directly relevant to the jury’s assessment of Agent Beals’ credibility, methodology, and conclusions in this case,” Rinderknecht’s lawyers claimed.
