A 3-year-old boy's godmother and her boyfriend have been arrested after the boy was found apparently beaten to death in her Patchen Avenue home.

Police have charged Nymeen Cheatam and Lemar Martin with assault and acting in a manner to injure a child.

Police say Kyle Smith had a broken leg and was sodomized with an unknown object before he died Friday. The superintendent of the building tells News 12 Brooklyn that Smith had been staying with his godmother because his birth mother was a drug addict, who had to give up custody. The medical examiner is working to determine exactly what killed the boy.
