In recent years, Gordon found himself entangled in legal drama after his girlfriend Laura Leal accused him of a physical altercation.

Due to those statements contradicting her original ones, prosecutors decided not to go through with a trial following the review of body camera footage, the911 audio, sworn statements and jail call recordings, and announced that Gordon would not be charged.

“With no independent witnesses to the incident, prosecutors do not have a good faith basis on which to proceed to trial,” prosecutors said in the statement.

Gordon was previously arrested in June 2017 on domestic battery and false imprisonment charges after Leal filed a police report alleging her boyfriend had beaten her and held her in her home. The charges were dropped in August of that year.

Leal was Gordon’s latest high-profile romance since the death of Brown.
