WASHINGTON PARK — Two Washington Park teenagers were charged Friday with aggravated criminal sexual assault in connection with the alleged molestation of their young relatives.

St. Clair County States Attorney Brendan Kelly charged Demarkus Kidd, 16, with five counts of aggravated criminal sexual assault. And Deshaune Porter, 15, was charged with four counts of aggravated criminal sexual assault.

The criminal complaint alleges that they had sex with females ages 5, 6 and 12 between July 11 and July 26.

Washington Park Police Chief David Clark said the suspects are relatives of the girls.

Both juveniles will be prosecuted as adults. They were being held late Friday afternoon at the St. Clair County Juvenile Detention Center in lieu of $750,000 bail.

Kelly said, "Under Illinois law, aggravated criminal sexual assault is a crime of excluded jurisdiction, meaning that despite their ages, Kidd and Porter will be prosecuted as adults."

If convicted, Kidd and Porter face up to 30 years in prison.

The case was investigated by the Washington Park Police Department.

Kelly was pleased with the work the police did on the case.

He said, "Despite having few resources and being severely undermanned, the Washington Park Police worked this case very hard and I am thankful for that."

Clark said a family reported the alleged molestation to police.
