"Nearly nine years ago, Desmon Venn threw a single punch at a high school classmate and put him in a coma. Venn pleaded guilty to assault, spent two months in a boot camp and figured he had paid his debt to society. Then, last month, the victim died of his injuries, and prosecutors brought involuntary manslaughter charges against Venn. Now 26, he could get up to 15 years behind bars if convicted in the death of Zuhair Pattah," the A.P. is reporting here.
