Hall, who has been an officer for more than seven years,is on paid administrative leave, which is department policy.
But we are also learning that Hall was involved in a deadly shooting in November 2018.
Hall shot and killed 33-year-old Laudemer Arboleda of Newark, who police say led officers on a pursuit, and steered his vehicle toward an officer.
Witnesses at the time disputed that claim from police.
