He faces 25 years to life in prison for what DNA evidence has supported happened to the now 14-year-old girl.
Prosecutors alleged at trial that Maraj started abusing the victim when she was 11, and raped her repeatedly between April and November 2015 while her mother was working, Brosh says.
The prosecutor said DNA evidence recovered from the girl's pajama trousers was linked to Maraj.
The accuser, now 14, girl testified that Maraj, 38, anally raped her at one point, slapped her in the face and ordered her to remain mute about his actions.
Throughout the trail it was rumoured that Nicki may have been called as a witness in her brother's defence, but neither she, nor her brother, took the stand.
The prosecutor told the jurors it will be up to them to determine whether the testimony of the two children was credible. Slane asked jurors. "This isn't a Broadway show".
A defense lawyer claimed that the girl's mother created a "shakedown". James R. Ray III, a civil attorney who briefly represented the mother, testified that he did demand $25 million from Jelani Maraj after he had already been arrested to settle a potential lawsuit, but he said the girl's mother was unaware of the demand. The girl testified that Maraj treated her as his own daughter before he began raping her.
Neither Maraj nor his sister, whose birth name is Onika Tanya Maraj, testified in the trial.
According to CBS News, Maraj's attorney said he will appeal, as he believes the sexual assault allegations were a ploy by Maraj's now ex-wife, Jacqueline Robinson, who allegedly wanted to extort him for $25 million to keep quiet.
Nicki Minaj was not called as a witness, and she has not publicly commented on the case. But social media is torn up about how media continues to involve Nicki Minaj in the news. Ms. Minaj has been nominated for a Grammy award 10 times and won six American Music Awards.
