In a press release from Jimmy Lee, Director of Public Affairs for the Office of the Contra Costa Sheriff-Coroner on Friday, May 31, 2024, Sheriff-Coroner David Livingston announced that a coroner’s jury had reached a finding in the March 23, 2023 death of 31-year-old Ryniqueka Dowell and March 27, 2023 death of 6-year-old Jamari Humble. The finding of the jury is that the manner of death is at the hands of another person, other than by accident.

The coroner’s jury reached the verdict in the inquest after hearing the testimony of witnesses called by hearing officer Matthew Guichard.

As previously reported, on March 23, 2023, at about 7:27 pm, the Hercules Police Department received information from the Contra Costa County Sheriff’s Office regarding a stolen 2021 Mazda SUV, possibly heading toward the City of Hercules on eastbound I-80. A Hercules Police Officer saw the Mazda exit I-80 eastbound onto northbound Willow Avenue. As the Officer caught up to the Mazda, the driver immediately began to accelerate. The Officer initiated a short pursuit of the SUV, before it collided into a 2017 Nissan passenger vehicle in the area of Parker Avenue and 4th Street in the City of Rodeo. The driver of the Mazda immediately got out of the vehicle and ran northbound onto Parker Ave. A perimeter was established, and the suspect was found, at a nearby liquor store. He was placed under arrest, and later transported to the Martinez Detention Facility.

The driver of the Nissan passenger vehicle was a 31-year-old, mother of twin boys, age six, later identified as Dowell.

On March 28, 2023, the Contra Costa DA’s office filed murder charges as part of a six-count felony complaint against then-20-year-old Ralph Ellsworth White, III of Vallejo (born Feb. 11, 2003).

A coroner’s inquest, which Sheriff-Coroner David Livingston convenes in fatal incidents involving law enforcement personnel, is a public hearing during which a jury rules on the manner of a person’s death. Jury members can choose from the following four options when making their finding: Accident, Suicide, Natural Causes, At the hands of another person, other than by accident.

According to a GoFundMe account set up to support the surviving twin son, Jamani Humble, and his father, Jeffrey, Jamani “suffered a broken leg along with other injuries” and Jamari was initially in the hospital “in critical condition…without any brain activity” but later succumbed to his injuries. As of Saturday, June 1, 2024, $38,395 had been raised toward the $50,000 goal.

According to the Contra Costa Sheriff’s Office the six-foot, 190-pound White is being held on no bail in the Martinez Detention Facility and his next court appearance is scheduled for Sept. 9, 2024.
