BLADENBORO, N.C. — A young black man is dead. The police are roundly criticized. Angry protesters march through the streets.

But unlike the deaths of black men in New York and Ferguson, Mo., the death of 17-year-old Lennon Lacy in this tiny lumber town was not known to be at the hands of a white cop — or any cop. After Lacy was discovered hanging from a trailer park swing set Aug. 29, authorities quickly ruled his death a suicide.
