After gaining national notoriety in the late 1990s for being accused of transmitting HIV to at least 13 young women in Chautauqua County, New York—including a 13-year-old—a 32-year-old man formerly known as Nushawn Williams was denied parole for a fifth time on April 6, The Buffalo News reports.

“This individual perpetrated some heinous crimes against some very young victims, and he forever changed their lives,” says Chautauqua County Sheriff Joseph A. Gerace. “He deserves to be in jail for as long as he possibly can be.”

According to the article, Williams—who now goes by the name Shyteek Johnson— pleaded guilty to two counts of second-degree statutory rape and one count of reckless endangerment in February 1999. That same year, in an interview with New York City television station WPIX-TV, Johnson admitted to having sex with between 200 to 300 young women before his arrest, adding that he was wrong in not wearing condoms.

“I owe them an apology for that,” he said. “I didn't do it the safe way. That's my wrongdoing.”

Johnson will be released in 2010 when his 4- to 12-year prison sentence expires.
