Two Chicago mothers have filed a lawsuit against the owners of their apartment complex after a bottle of acid was dumped onto their two children by another child in the complex. The women claim in their lawsuit that the apartment owners were negligent in leaving the drain cleaner – which was 93 percent sulfuric acid – out for the children to get into. The 13-year-old boy who dumped the acid on the other kids has been charged with heinous battery and held on a delinquency petition.
