Andre Walker is a gay, black man who enjoyed his life of casual sex and drugs. He had a record of drug offenses that left him with parole standards intended to prevent him from returning to substance abuse.
Andre would regularly have sexual trysts with Kyle Swanson, a campaign donor, but Swanson regularly sexually assaulted, exploited, and domineered Andre for pay, taking hundreds of thousands of dollars from Swanson for degrading Andre with numerous sexual acts and positions while shooting him up with drugs. It was bad enough Andre overdosed and nearly died the last time, which Swanson only cared to delight in more from a sense of godlike power, but Andre never met Swanson again to protect himself.
When Swanson was tracked after having killed gay, black men with drug overdoses, Andre was questioned and he told his account. He was originally afraid to testify because his parole would've been violated with, but the team encouraged him to support other gay, black men like him who could be exploited and endangered by criminals like Swanson. With this, Andre testified, which secured Swanson's conviction. Kate Dixon, who personally invested herself in the case because of tracking Swanson's crimes for years, went to testify in front of the parole board in hopes Andre wouldn't be penalized.
