Last-Minute Confession Witness Disrupts Lassen County Double-Homicide Trial

A review of the court file of Isacc Anthony Pedroza revealed new information in the case. The defendant’s next court appearance is scheduled for 8:30 a.m. Feb. 24.

Pedroza is charged in a double-homicide shooting event that occurred Dec. 6, 2025 at the eastern edge of Lassen County.

According to the court file Pedroza faces three felony counts regarding the incident.

Count 1 alleges Pedroza “did lawfully and with malice aforethought murder Spencer Browne,” and that the murder “was committed willfully, deliberately and with premeditation.”

Count 1 also carries the special allegation, of a “personal and intentional discharge of a firearm causing great bodily injury or death,”

Count 2 alleges Pedroza “did lawfully and with malice aforethought murder Richard Browne.”

Count 2 also carries the special allegation, of a “personal and intentional discharge of a firearm causing great bodily injury or death,”

Count 3 alleges unlawful assault weapon activity in that Pedroza “did unlawfully transport into this state an assault weapon identified as a Springfield XDM 9mm with a threaded barrel and extended capacity magazine.”

The prosecution plans to present testimony from more than a dozen witnesses.

According to the court file, “On Dec, 6, 2025, at approximately 8:45 a.m. the defendant shot Richard Eugene Browne and Spencer Browne on Highway 395 in an unincorporated area of Lassen County, just mere feet north of the Sierra County Line. The People believe this fact is undisputed. The burden for the People in this case will not be to prove that the defendant killed Richard and Spencer Browne, but his intention in doing so; and whether his actions rise to the level of murder, and if so, in what degree.”
