Prosecutors in the R. Kelly sex trafficking trial wrapped up their case Monday after calling dozens of witnesses over the previous month. The witnesses described their experience with the singer in graphic detail.

Later in the day, the defense began calling Kelly supporters to the stand in an attempt to cast doubt on some of the victims’ statements.

A New York City jury heard several women and two men in Kelly’s celebrity circle who described how he had groomed them for unwanted sex. They claimed that Kelly mentally tortured them when they were adolescents. The people that used to work for Kelly testified that they were effectively paid to look the other way or actively help the recording artist.

Kelly’s lawyers are set to rebut testimony from victims who claim Kelly had engaged in aberrant behavior over a three-decade period. Witnesses claim he gave them herpes without disclosing he had an STD. One witness said Kelly shot a humiliating video of one victim spreading feces on her face as punishment for breaching his rules.

Kelly’s sex abuse allegations were described by one prosecution as “about a predator” who exploited his celebrity to lure children, boys, and young women before dominating and manipulating them physically, sexually, and mentally.

A significant portion of the evidence centered on a notorious incident involving his youngest and most well-known victim, R&B sensation Aaliyah. Kelly allegedly sexually abused Aaliyah when she was 13 or 14 years old, according to one witness.

Aaliyah, whose full name was Aaliyah Dana Haughton, collaborated with Kelly on her debut album, “Age Ain’t Nothing But A Number,” which was released in 1994. Aaliyah died in a plane crash when she was just 22 in 2001.

Kelly has strongly rejected the allegations, saying that the women were groupies who sought to take advantage of his fame and money until the #MeToo movement turned them against him.
