Martinez, California — The Contra Costa District Attorney’s Office has concluded its investigation into whether the mother of Marshall Curtis Jones, III acted as an accessory after the fact in connection with the death of Alexis Gabe in January 2022.
Since the May 26, 2022, charging of Marshall Curtis Jones with the first-degree murder of Alexis Gabe, and Jones’ subsequent death while law enforcement was serving him a warrant in Washington State on June 1st of the same year, the District Attorney’s Office remained committed to investigating all possible avenues of criminal liability. This commitment included evaluating whether any individual, including Jones’s mother, Alicia Coleman-Clark could bear criminal liability for actions taken after the crime.
Following a detailed meeting with Alexis Gabe’s family in December 2024, the District Attorney’s Office, along with the Oakley and Antioch Police Departments, pursued additional investigative leads. These efforts included:
- Forensic Examination of Recovered Clothing: Additional forensic analysis of a shirt recovered with Alexis Gabe’s remains was conducted to determine the presence of gunshot residue (GSR). The results found no evidence of gunshot residue or any indication that the shirt had been penetrated by gunfire – which is consistent with prior forensic findings.
- Investigation of a Second Black Plastic Bag: While a second black plastic bag with Alexis’s remains was recovered by search and rescue personnel in Amador County, that second bag was not with the remains sent to California State University, Chico for forensic testing. While no identifiable DNA was found on the first recovered bag, law enforcement pursued the whereabouts of the second plastic bag. After an exhaustive effort by Antioch and Oakley Police to determine its whereabouts, law enforcement confirmed to the District Attorney’s Office the bag was never provided to any local law enforcement agency. As such, there is no second bag to test for the presence of a contributor’s DNA.
- Re-interview of Alicia Coleman-Clark’s Former Boyfriend: Investigators conducted a follow-up interview with Ms. Coleman-Clark’s former boyfriend to clarify prior statements he made to law enforcement in 2022. He reiterated that a reference made by Coleman-Clark to something “cold” related to a soda can and not to Alexis Gabe’s remains. His account is consistent with his prior statements, and no evidence has been found to contradict his explanation regarding a cold soda can.
- Search of Flight Purchase Records: Investigators obtained a warrant to search airline ticket purchase records for Marshall Jones’ flight to Seattle, Washington in February 2022 to determine whether Ms. Coleman-Clark had facilitated the purchase. The records obtained did not indicate any purchase activity involving Coleman-Clark. It appears the flight was arranged through a third-party vendor — and no further purchase details have been identified by law enforcement.
Legal Determination
The District Attorney’s Office determined that while some information raised suspicion about Alicia Coleman-Clark’s potential culpability as an accessory after the fact under Penal Code Section 32, there are plausible alternative explanations that point against her guilt under the same statute.
Therefore, after a thorough review of the totality of the evidence, the District Attorney’s Office has concluded there is insufficient evidence to prove beyond a reasonable doubt the elements required to charge that Alicia Coleman-Clark acted as an accessory after the fact under Penal Code Section 32.
Statement from District Attorney Diana Becton
“We extend our deepest condolences to the Gabe family for the unimaginable loss of Alexis. Our office has worked tirelessly over the past three years to pursue every lead. While we have concluded our investigation into this matter, we remain committed to supporting the Gabe family.”
