"Masked detective testifies in YNW Melly murder trial while defense raises concerns"

An undercover detective, who is an expert on gangs, testified in the murder trial of rapper YNW Melly, wearing a mask due to death threats he received. The defense challenged the detective's right to testify without showing his face, citing the defendant's right to confront his accuser. The witness tied Melly to membership in a Bloods offshoot gang. The trial also saw arguments over whether a cell phone found in the Jeep where the victims were killed belonged to Melly.
