Stephon Clark activists are turned their focus to California Attorney General Xavier Becerra Monday, delivering a letter to state Justice Department officials urging Becerra to file criminal charges against the Sacramento police officers who shot Clark last March.

The Rev. Shane Harris, president of the People’s Alliance for Justice and a representative of Clark’s girlfriend and their two young children, plans to deliver a letter to Becerra’s staff at his I Street offices downtown and hold a news conference afterward in the latest effort to generate pressure over the issue.

Becerra has been conducting his own investigation of the shooting and is expected to announce the results soon, following the Saturday decision by Sacramento County District Attorney Anne Marie Schubert not to file charges in the case, the Sacramento Bee reports.
