On the night of May 9, 2016, 27-year-old Frank Cohens Jr., a Black man from Tacoma, was found slumped over the steering wheel of a car near the Weyerhaeuser campus in Federal Way, Washington. He had been shot multiple times; investigators determined robbery was the motive in his killing, distinguishing his death from other apparently random attacks in the city that spring.

Police linked Cohens’ death to a string of violent crimes that claimed three other men in Federal Way in spring 2016. Investigators reported Cohens was likely involved in drug activity before his death, which provided leads during the inquiry. After a lengthy investigation, authorities identified three suspects connected to the series of homicides. One was named Justice Henderson, then 17 at the time of the killings and already in custody for an attempted murder in Pierce County; another, Kamajah K.J. Skannal, then 20, was charged specifically in Cohens’ death with first-degree murder and first-degree robbery.

Anyone who knew Frank Cohens Jr., his movements in May 2016, or who has information about the robbery that led to his death is asked to come forward.
