Interim Police Chief Ed Kraus said Monday there was no indication the officers knocked on the front door, and Dean reportedly didn't identify himself as a police officer.

Kraus also said the officer would have been fired had he not resigned.

Jefferson's killing came shortly after Dallas police officer Amber Guyger was convicted of murder and sentenced to 10 years in prison after shooting and killing Botham Jean in his apartment. Guyger said she thought it was her unit.
