Robert Charles Pickle, 51, was found dead inside his home at 1417 McSpadden Street in Knoxville, Tennessee, on September 19, 2017. The discovery came during a welfare check; police immediately treated the death as a homicide and focused on reconstructing Pickle’s final hours — who had been with him, who had reason to come to the house, and who might have left evidence in the neighborhood.

Within hours investigators publicly named Mark Edward Phelan, described as 30 years old at the time, as a person of interest and asked the public’s help locating him. Police located Phelan the next day at a relative’s home outside Knox County and took him into custody on unrelated charges. He was interviewed about Pickle’s death but was not charged in the homicide at that time, and the case remained open without a publicly identified offender.

Does anyone have information about Pickle’s last known contacts or was in the McSpadden Street area on or around September 19, 2017?
