Bingham Berry Berresford, 64, was found dead in his West Oakland townhouse on January 25, 2011. Colleagues who had not heard from him for several days alerted police; officers found the door to his home on the 500 block of Henry Street ajar and discovered his body. Authorities treated the death as a homicide and reported signs of trauma, though the exact cause was not immediately clear.

Berresford had emigrated from Montego Bay, Jamaica, and was known locally for his activism and his role as political director for Service Employees International Union Local 1021. He had been working on a Head Start campaign in Stockton and was often away from home. No suspects were immediately identified, and the case remained unsolved at the time.

Does anyone who knew Berry or who saw him in West Oakland or Stockton around that time have information that could help investigators?
