Pan was later connected to a series of
drive-by shootings in the same area between December 11, 2020 and February 6, 2021. Four homes were shot at, but no one was injured. At every scene, one to five .45 calibre casings were recovered. The final shooting had occurred an hour before Jiang's murder. In both the non-fatal shootings and Jiang's murder, Pan had used a 2013
GMC Terrain from a car dealership in
Mansfield, Massachusetts, having taken it out for
test drives each time and not returned it after the killing. Investigators stated that the drive-bys were meant to mislead police into believing that Jiang's murder was a random act of violence.
