The cause of Knight's death will be determined by the Maricopa County Medical Examiner. The alleged crime occurred April 1, 2017.
Court documents obtained by TMZ Sports show the 39-year-old was arrested in Phoenix on June 14 and charged for sexual acts involving a girl that was nine.
Knight's body was found at 2:45 a.m. Sunday, and he was pronounced dead shortly thereafter by the Phoenix Fire Department. Phoenix police said there was no evidence of foul play. Knight died a day after posting a cryptic video on YouTube titled "I am sorry Lord".
Knight's death is the second of a former UCLA basketball player in the past week.

During the video, Knight becomes emotional as he repeatedly references his faith and calls on people with mental health difficulties to reach out to loved ones. I was a taker. Basketball coach Dinos Trigonis said on Twitter that he knew the Knight family for more than 20 years. You can't play around with life.
Knight was a fantastic player for the Bruins between 1997 and 2002, but unfortunately is yet another UCLA alum gone too soon. He follows by admitting to a life of sin, discussing mental illness, and apologizing to his family and friends. "I just asked God for forgiveness for all the wrong I've done". He also noted that he "felt like I didn't belong here on earth. I will be in Heaven or Hell".
He wasn't picked in the 2002 National Basketball Association draft but played professionally in France and Japan. At the time of his death, he had been on the staff of the Northern Arizona Suns, a developmental G league team affiliated with the NBA's Phoenix Suns.
