RIVERSIDE, CA – On Friday, March 10, 2023 at approximately 9:30 a.m., two members of the Riverside Police Department’s Park and Neighborhood Specialist (PANS) Unit were driving in the area of Bryant Park, located in the Arlanza neighborhood, as part of their daily park patrols.  They observed a vehicle drive recklessly by them and appear to meet up with another car in the parking lot.  There was some brief interaction between the occupants of both vehicles, who then left once they saw the PANS Specialists in their truck.  As both cars were leaving the parking lot, one of the involved vehicles accelerated toward the PANS truck in an attempt to ram or strike them, but fortunately they were able to avoid being hit.  The specialists began to drive from the area for their safety when they heard several gunshots coming from the vehicle that almost rammed into them.  They called for assistance and several officers responded, including the Problem Oriented Policing (POP) Team, but the involved vehicles were not located after an extensive search.


Over the next several days, members of the POP Team followed up into this assault on the PANS specialists.  Their investigation led to video being located that confirmed one of the involved vehicles deliberately sped toward the specialists and subsequently fired off a handgun, although the gunshots did not appear aimed toward the specialists.  Additional evidence determined the PANS Specialists had unintentionally interrupted a drug sales transaction involving these vehicles while they were patrolling the park. 


Ultimately, the POP Team obtained search warrants which helped lead to the identity of the primary vehicle driver suspected in the assault and shooting.  In fact, this same suspect had recently been arrested by our METRO Team and Gang Intelligence Unit for illegal narcotics sales and assault weapons violations occurring in August 2022.


On Thursday, March 16th and with assistance from the METRO Team, POP Officers located the primary suspect in the city of Norco.  While trying to apprehend him, the suspect attempted to flee from METRO Officers by intentionally ramming one of their vehicles, but he was safely taken into custody.


A search of the suspect’s vehicle resulted in the seizure of approximately 9 ounces of suspected fentanyl, 120 ounces of marijuana, 19 ounces of Psilocybin mushrooms, 320 packaged marijuana and Psilocybin mushroom candy, 9mm handgun, ammunition, large amount of cash, and other items indicia of the packaging and sales of illegal narcotics.


19-year-old Jean Marcos Jimenez of Riverside was arrested and later booked into the Robert Presley Detention Center for assault with a deadly weapon, negligent discharge of a firearm, possession of illegal narcotics and marijuana for the purposes of sales, weapons violations, intimidation and/or dissuasion a witness, and the commission of a felony while out on bail.  Once arrested, it was also learned the suspect had been in a sexual relationship with his 16-year-old girlfriend for several years, so additional charges were added for lewd and lascivious acts with a child and child endangerment. Jimenez is currently being held on $350,000 bail.


This investigation is still ongoing and there are no other details to release at this time.  Anyone with additional and relevant information regarding this arrest should contact POP Officer Michael Smith at (951) 826-8728 or [email protected].  Those wishing to remain anonymous can email [email protected], or download and use the Riverside Police Department’s “Atlas 1” mobile app by utilizing the “Send a Message” feature.  Our app can be downloaded at:
