Five adults have been accused of perpetrating crimes against five children inside a Darby house that are so heinous it's difficult to stomach.

From shooting the kids with BB guns to forcing an adult woman to perform oral sex on a 2-year-old boy, the case is the stuff of nightmares - but police allege it was the reality in which these helpless children were forced to live.

Shakia Jackson, 31; Daryl Carter, 24; Danielle Hammond, 22; William Wade, 23 and Mark Isom, 22, have all been arrested in connection with the case. Their offenses range from endangering the welfare of children to corruption of minors and from simple assault to involuntary deviate sexual intercourse.

The Delaware County District Attorney's Criminal Investigation Division began investigating the alleged crimes occurring at the house on 7th Street near Cedar Avenue in June. All of the adults charged in the case either lived at the house "or hung out at the residence," according to court documents. Jackson and Carter listed the residence as their address to police, while the other three defendants provided Philadelphia addresses, according to court paperwork.

All of the five victims were under 12 years old, though their individual ages, aside from a 1-year-old and a 2-year-old, were not detailed in the affidavits. The 1-year-old is Hammond's child while the other four children are Jackson's kids, according to court documents.

Police said the physical abuse the children suffered ranged from punching and slapping to getting shot repeatedly with three different BB guns and being thrown over a banister.

Jackson allegedly admitted shooting her children with BB guns, but she told police that "she and the other adults were only playing and the children wanted to be shot," according to court documents.

The children also were forced to witness sex acts the adults performed on each other and in one incident, the three men accused in the case allegedly held down one of the accused women and forced the 2-year-old's genitals in her mouth, police said.
