There was no drugs involved with the couple. Even the murderers admitted as such. The only reason that was even suggested was because several of the typical East Knoxville race baiters were posting it on social media, claiming it was the reason because the area was getting so much heat from it on the news.
The thugs admitted that they had been driving around looking for someone to carjack and/or rob, and they just happened upon the two as they were standing outside their car OUTSIDE their friend's apartment...
You are clueless as usual and this is backed by court documentation and the police report.
