David McNaughton, a deputy Chicago police chief with connections to the Laquan McDonald case, reportedly retired on Friday.
McNaughton's retirement comes after the release of a city inspector general report, which called for the firing or discipline of at least 10 cops with ties to the McDonald case, according to the Chicago Sun-Times.
Chicago Police Supt. Eddie Johnson has not yet taken any formal action on the IG's report.
Police accounts of the McDonald shooting conflicted with what was shown in the dashcam video of the incident.
Police dashcam video captured Officer Jason Van Dyke shooting McDonald 16 times as the African-American teen walked away from police. Van Dyke was charged in November with first-degree murder in the 2014 shooting death of McDonald.
McNaughton wrote in the McDonald police report that "Officer Van Dyke fired his weapon in fear of his life when the offender while armed with a knife continued to approach and refused all verbal direction."
