OAKLEY >> Prosecutors do not have enough evidence to charge the mother of a man suspected in the disappearance of Alexis Gabe, a 24-year-old Oakley woman who vanished in January and now is presumed dead.

Gabe’s family met with Contra Costa County District Attorney Diana Becton and Chief Assistant District Attorney Simon O’Connell on Wednesday afternoon to demand that aiding and abetting charges be brought against Alicia Coleman Clark. They believe Clark helped her son, Marshall Curtis Jones, 27, in the events that left Gabe missing.

Authorities on June 1 said they considered the case a homicide investigation, and prosecutors filed murder charges against Jones. Members of the Pacific Northwest Violent Offenders Task Force shot Jones to death in Kent, Washington, that night, saying he came at them with a knife as they moved in to arrest him.Gabe » Page 2

Gwyn Gabe, Alexis’ father, spurred the recent demand for Clark’s arrest after posting a police release on the timeline surrounding his daughter’s disappearance on a Facebook page dedicated to finding her.

“As Alexis’ parents, you all know that we want justice, and we want it now,” the Gabe family wrote in a statement on the page Wednesday. “Instead, we got almost two hours of explanations ... about how they could not do anything immediately. We were told that we just have to wait. We are beyond frustrated and upset at being told that we have to wait.”

Becton, in a statement, said, “It was a productive meeting. And it was good to have Mr. and Mrs. Gabe, law enforcement and attorneys in one room so everybody could appreciate the state of the ongoing investigation.”

Alexis Gabe vanished the evening of Jan. 26 after visiting ex-boyfriend Jones at the home he shared with his stepfather on Benttree Way in Antioch.

Her light blue Infiniti was found the next day 4.5 miles away on Trenton Street in Oakley, but there was no sign of Alexis.

Her whereabouts remain unknown.
