Detectives To Ask For Public’s Help In Locating Missing Juvenile Who Is Also a Person Of Interest In Fatal Hit & Run, Rosemead

On Friday, November 12, 2021, Temple Station Detectives asked for the public’s assistance locating 16-year-old Mariano Coc, who was last seen at his residence in South El Monte on Sunday, November 7, 2021.  

Mariano is also the person of interest in a fatal hit and run incident that occurred in the City of Rosemead on Monday, November 8, 2021.

At approximately 10:30 AM, an altercation took place between two individuals on the 2700 block of San Gabriel Blvd, near the intersection of Garvey Ave in the City of Rosemead. That altercation resulted in the death of 61-year-old Riverside resident Haiou He.

Upon further investigation, it was determined that a possible traffic collision between two parties and had escalated into a verbal argument. At that time, the victim exited his vehicle to speak with the other vehicle’s driver. During the confrontation, the driver, who was still seated in his vehicle, placed it into reverse and subsequently ran over the male victim, causing life-threatening injuries. The victim, unfortunately, passed away from his injuries on Wednesday, November 10, 2021.

Immediately after the incident, the suspect, driving a 2009 black Nissan Altima with a grey bumper, fled the scene, driving northbound on San Gabriel Blvd and out of view. The vehicle used in the crime has since been located.

During the investigation, it was determined that the vehicle belonged to a local family, and the last person to be seen with the vehicle was 16-year-old Mariano Coc.

Mariano, along with the vehicle, were last seen on Sunday, November 8, 2021, between 5:00 AM and 7:00 am.

According to multiple witnesses at the scene, the driver’s description of the fatal hit and run does not match Mariano’s description.

At this time, Mariano is still missing, and Detectives are worried that he may have become the potential victim of a crime. 

Mariano was last seen wearing a tan tank top, light-colored jeans, and black slip-on sandals. He is 5’07”, 145 pounds, and has brown hair and brown eyes.

Sergeant Richard Lewis asked for public’s assistance, “If anyone happened to see a collision prior to this instance, or heard the altercation…we’re asking for the public’s help with this.”

Detective Karina Bravo provided remarks to the media in Spanish.
