Texas judge denies new trial for convicted murderer Karmelo Anthony in the killing of Austin Metcalf.

Newly surfaced evidence included threatening text messages Anthony sent the morning of the murder, including: "How many bullets u want coming out of ur chest?" and "When I stab somebody I'm gonna lick their blood off the blade."

Anthony will remain in prison. The victim's family has endured years of legal proceedings since Metcalf's death.
