Murder charges are filed against a Vallejo man in the deaths of two young women in Napa Valley. Napa County District Attorney Allison Haley has confirmed that 22-year-old John Richard Wesley Nicholson Jr. is facing allegations of homicide for an incident that left a 19-year-old woman and a 17-year-old girl dead. The fatal confrontation unfolded on April 13, in the 400 block of Riverside Drive in Napa at around 8:10 p.m.

The charges leveled against Nicholson are severe, comprising two counts of murder and the special circumstance of committing multiple murders. He is further accused of discharging a firearm intentionally and causing death—a claim aggravating the case. According to the Napa County District Attorney's Office, the crimes were marked by "great bodily harm and involving a high degree of cruelty, viciousness, and callousness." Missteps such as sophistication and premeditation are ascribed to Nicholson's alleged actions, painting a grim picture of the events that transpired.

Nicholson, who appeared in court for his arraignment, has yet to enter a plea and has been appointed a public defender. The Napa authorities aren't stopping at Nicholson. The District Attorney's Office is probing the potential involvement of Jessica Whitten and Judith Adolph, both 19 and from Santa Rosa, who are currently under arrest in relation to the killings.

As the investigation proceeds with meticulous attention to detail, Deputy District Attorney Agnes Dziadur, along with Investigator Nick Conrad, are joined by the Napa Police Department in building a case against the accused.
