Valerie Jamison was a 25-year-old Black woman who disappeared from the streets of Philadelphia in the spring of 1987. She is believed to have entered an apartment in April 1987 and never been seen alive again; investigators later tied her disappearance to a series of killings in the same building.

In August 1987 the landlord responded to a foul odor and police discovered multiple human remains in various states of decomposition inside Harrison Graham’s apartment. Jamison’s body was among those found; severe decomposition initially made immediate identification difficult. Examinable victims showed signs of strangulation.

Harrison Graham was arrested on August 17, 1987, and confessed to killing seven women after taking drugs with them during sexual encounters. He was tried in 1988, convicted on seven counts of first-degree murder and abuse of a corpse, and originally sentenced to death. Anyone who knew Valerie Jamison or has information about her last movements is asked to come forward.
