Milwaukee ? Two more people were charged Friday in the case of an 11-year-old girl who authorities say had sex with as many as 20 people as a 16-year-old girl coached her.

Freeman Gurley, 40, the 16-year-old’s uncle, and Darnell Chaney, 17, were charged with two counts of first-degree sexual assault of a child.

The 16-year-old girl and a 15-year-old boy also have been charged in juvenile court with being a party to sexual assault of a child. A police spokeswoman said they were still seeking five others in the case.

Also on Friday, Alderman Mike McGee Jr. said he met with the girl, whom he described as distraught. He said she has been infected with HIV since birth and that her mother died of AIDS.

The likelihood of someone spreading the AIDS virus through a single sex act is not well-known. A key factor is how much virus is in the infected person’s blood, according to Johns Hopkins University researchers who have studied the topic. Treatment with AIDS drugs greatly reduces the amount of virus in the blood.
