Three (3) suspects have been arrested for their involvement in the deadly assault on Wednesday, May 25th; Javier Guevara is still wanted for murder.


On Wednesday, May 25th, 2016 at approximately 4:51PM, two juveniles, both students of Novato High School, were viciously attacked on a public trail within Open Space near the end of Fairway Drive, Novato. Seventeen year old Edwin Josue Ramirez, was killed at the scene of the attack while the other (unnamed) juvenile who had been both shot and stabbed by his attackers, was able to escape and call 911.

During the past eight days, Sheriff’s investigators have been working an overwhelming number of clues, tips and leads in pursuit of those responsible for this attack. In result, the Sheriff’s Office working in concert with many of our allied agencies have conducted three (3) high risk tactical operations where a total of three (3) suspects have been arrested for their involvement in the deadly assault on Wednesday, May 25th, they are;

  • Suspect #1. HENRIQUEZ, Jaun Carlos Martinez, HMJ, 10-18-1968 Arrested during execution of Search Warrant at 405 Rowland Boulevard, Novato on Thursday, May 26th, 2016

  • Suspect #4. GUEVARA, Javier, HMA, 3-15-1997 (brother of suspect #2) Suspect still WANTED for MURDER, Armed and Dangerous.

A fourth high-risk tactical operation was conducted earlier this morning pursuant to a Search Warrant at 15 South Norfolk Street, San Mateo. This was conducted with the assistance of the San Mateo Police Department and the San Mateo Regional Special Response Team. No suspects were arrested and no details of any evidence, clues or leads developed during the execution of the Warrant will be released at this time.

Please note this is still a very active and intense investigation, and at the same time it is very intense and emotional to so many impacted by this tragic event. The Marin County District Attorney’s Office has filed complaints against all four (4) of these suspects including against suspect GUEVARA, Javier, who is now wanted on a $100,000

Felony Warrant issued for his arrest. The two suspects in custody charged for Murder and Attempted Murder (Jaun Carlos Martinez Henriquez & Edwin Oswaldo GUEVARA) will face direct filing charges in the Adult Court System, both will have special circumstances alleged. Neither juvenile defendants will face the death penalty because they were juveniles at the time of these offenses and under court decisions as well as California statutory law the death penalty cannot be imposed.
