The oldest man charged in the case of an 11-year-old girl who authorities say had sex with as many as 20 people says she had looked like she was 19 or 20 to him.

"She looked grown to me, man," Freeman Gurley said in a telephone interview Sunday night with the Milwaukee Journal Sentinel from the Milwaukee County Jail.

Gurley, 40, who has been charged with first-degree sexual assault of a child, said he was sorry he got involved and did not do anything to stop what was going on in his house last week.

He told the newspaper that, after returning home from work, he went to a locked bedroom in his house where he heard moaning from inside and eventually was let into the room, where he saw "12, 13 or 14" other men and teens present.

Gurley said the girl was freely having sex with several men during the hour he was present, but another man in the room had told her not to have sex with Gurley. She eventually acquiesced, he said, at someone else's urging. The criminal complaint said that person was the 15-year-old boy who is also charged.

Alderman Michael McGee said Friday that the girl had been infected with HIV since birth and her mother died of AIDS.

Gurley said in his interview that he has resigned himself to believing he now has HIV and that he's sorry about participating, and allowing the incident to go on, now that he knows her age.

"That's terrible, man," he said.
