I need some help. Can anyone tell me how long bruise marks on a 4 year olds legs would last? The child is African American and was beaten with a belt, strap or ruler about 1.25 inches wide. Supposdly it happened in June/July but was still very visible at this present date. There was still some small red scabs along the edges where the instrument had cut into his legs. Any help would be greatly apprieciated.
