Report: Tests show no drugs in Aaron Hernandez's system at time of death

Hernandez, the former Patriots tight end who was serving a life sentence for murder, hanged himself in his jail cell and was found dead April 19 at a Massachusetts prison. Newsweek had reported that an autopsy showed K2, a form of synthetic marijuana, in Hernandez's system. Sources told the WCVB that Hernandez used his own blood to draw a pyramid image, similar to the "all-seeing eye of God" that's on the back of US currency, on the walls of his cell. Hernandez also wrote the word illuminati in capital letters under the pyramid.
