What a gross way to end the week. There are no smiles here, just negativity…

First, Variety reports that actress Shannon Richardson, who has appeared on AMC’s “The Walking Dead” and “Vampire Diaries,” was arrested Friday afternoon in connection with ricin-laced letters sent to President Obama and New York mayor Michael Bloomberg. NBC News first reported the arrest. News comes two weeks after Richardson had reached out to authorities claiming her husband, Nathan Richardson, had sent the letters. Nathan, an army veteran, has since been questioned by the FBI. Shannon recently contacted authorities claiming she had found suspicious materials in her refrigerator that could be connected to the letters but investigators are now saying she was the one who sent the letters. “You will have to kill me and my family before you get my guns,” the message sent to Bloomberg read, according to NBC New York. “Anyone who wants to come to my house will get shot in the face. The right to bear arms is my constitutional God given right and I will exercise that right till the day I die.” Richardson is currently at federal court in Texas awaiting arraignment.

In other news, AP reports that Richard Ramirez, pictured above, the demonic serial killer known as the “Night Stalker” who left satanic signs at murder scenes and mutilated victims’ bodies during a reign of terror in the 1980s, died early Friday in a hospital, a prison official said. Ramirez, 53, had been taken from San Quentin’s death row to a hospital where authorities said he died of liver failure. Prison officials said they could not release further details on the cause of death, citing federal patient privacy laws. Ramirez had been housed on death row for decades and was awaiting execution, even though it has been years since anyone has been put to death in California. At his first court appearance, Ramirez raised a hand with a pentagram drawn on it and yelled, “Hail, Satan.” His marathon trial, which ended in 1989, was a horror show in which jurors heard about one dead victim’s eyes being gouged out and another’s head being nearly severed. Courtroom observers wept when survivors of some of the attacks testified.

Ramirez was convicted of 13 murders that terrorized Southern California in 1984 and 1985 as well as charges of rape, sodomy, oral copulation, burglary and attempted murder. Read the entire story at AP.
