According to a police report obtained by the Miami Herald, the boy told his mother the two had sexual intercourse and that he later heard that the older man was HIV positive.

Sumlin was arrest last Wednesday after the mother took her 15 year old son to Memorial Regional Hospital in Hollywood, Florida for an HIV test and unfortunately for the teen, the preliminary result was positive.

Before they had sex, Sumlin said he was 21 and asked the boy, “Are you really 18 years old?” according to the police report.

From the report: “The def asked ‘Are you really 18 years old,’ and the victim replied ‘no.’ The def then asked, ‘Are you 17,’ at which point the victim replied, ‘Younger.’”

The teen later told a friend that he had met Sumlin via a mobile phone app and that he had invited the man to his home in Pembroke Pines, where they had sex without condoms.

The friend told the boy that Sumlin was HIV positive and “has a secret Facebook page wherein he posts videos of himself engaging in anal sex with males that appear to be under the age of 18,” according to the police report.

Pembroke Pines police detective Michael Silver wrote in his report that during the investigation he viewed a video of Sumlin posted on a social networking website.

“I f—ed this little boy, videotaped it and added it to the online group,” Sumlin said in the video, according to the police report.

“And I don’t use condoms when I have sex and you call me sick, don’t worry about me, worry about who gave it to them.”

Sumlin admitted to authorities that he had sex with the teen but says he wore a condom. He is being held at the Broward County Jail on $280,000 bond.

Police believe there may be more victims. If you have any information, call Pembroke Pines police at 954-436-3200.
