Sean Austin Pollum, a 20-year-old from Jupiter, Florida, was found shot to death on October 8, 2015, in an apartment on Tamarind Avenue in West Palm Beach. He was discovered alongside 33-year-old local rap artist Brian Tanksley, known as Cook Em Up; both men had been shot multiple times.

Investigators later arrested 21-year-old Joshua Daniel Brown of Grey, Tennessee. Authorities say hair fibers on Pollum matched Brown’s DNA and phone records contradicted Brown’s initial alibi. Brown was apprehended by the U.S. Marshals Service in Washington County, Tennessee, and extradited to Palm Beach County to face two counts of first-degree murder. During the trial, prosecutors dropped the charges while jury selection was under way; no conviction followed and the case remained unresolved.

Who knew Sean or Brian, or has information about the events at the Tamarind Avenue apartment on October 8, 2015?
