During interviews with law enforcement agents in Washington, Adams provided details about the Chassereau case that were not public knowledge.

At the time of Chassereau’s death, Adams was renting a room on Grace Street in Richmond and was known to sell drugs to homeless people at the Acca yard. Chassereau was a customer, according to investigators.

Adams also was linked to an earlier death of a transient freight-train rider in California. On Jan. 21, 2000, the body of John Semler Owens, 46, was found on a gravel service road at a large railroad yard in Roseville, Calif.

Six months after his Washington arrest, Adams pleaded no contest to second-degree murder in the California case and later was sentenced to 15 years to life.

He recently was brought to Virginia to serve the remainder of that sentence, as well as the life sentence to which he has agreed here. Adams is due in Henrico Circuit Court today at 1:30 p.m., when he’s expected to accept the plea agreement.

During a hearing in February, in which Adams appeared via video link, he wished the judge a happy Hanukkah.

The case has been continued every month since February as the terms of the agreement were being ironed out, not by Adams’ attorney and prosecutors but between governors. California Gov. Jerry Brown had to sign off on Adams’ transfer to Virginia, a state that doesn’t allow for parole. California does have parole.
