Diane Simmons (formerly Seidelman) was Tom Tucker's co-anchor on Quahog 5 News. Although when the series started, she and Tom seemed to have a healthy and at times possibly sexual relationship, that quickly changed to where they instead bicker a lot on the air, and she soon became the butt of his jokes. This relationship started spiraling around the time of her 40th birthday. She also hosted a talk show called Diane!, on which the Griffins were guests and exposed their secrets. She once had a husband, before he committed suicide, as commented once by Tom on the air, causing her to break down crying. She admits to being a bit of a bigot, such as once openly joking on the air that she is racist against black people, though she believed they were off the air since Peter Griffin had cut off Quahog's television signal. During the Special People's Games she and Tom commented together how watching the game would give them all a sick sort of laugh, and how all of them were most likely going to hell for it. She is also a dedicated actress having done some pretentious student films in college. At one point, she was set to play the role of Anna in The King and I having stolen the role from Loretta Brown, during Lois Griffin's first theatrical production. Unfortunately, Peter Griffin, who stole control of the show from Lois as producer, later changed the script so massively much that even Diane couldn't stand the direction the show was taking and quit. Tom and Diane eat Asian reporter Tricia Takanawa, although this event was non-canonical. finally Diane reveals she has turned 40, and becomes the murderer of James Woods, Muriel Goldman, Derek Wilcox, Priscilla and Stephanie. She explains her plan to murder Woods and frame her co-anchor, Tom Tucker to Lois, nearly murdering her as well. It was revealed that she dated Woods and Tom successfully convinced the network to replace her at the news desk, as well as Woods dumping Diane, which resulted in Diane to seek vengeance. However, before pulling the trigger, she is shot and killed by Stewie and falls off of a cliff to her death because only he is allowed to kill Lois. In a message on his Twitter account, Seth MacFarlane confirmed that the episode was canon and that Diane is dead. she killed Stephanie by setting up a firearm to cook off and pointed it at the head seat at the table. Stephanie was an unintended victim, as the bullet was intended for James Woods, who was to sit at the head of the table. She stabbed James Woods during a power outage in revenge for him dumping her. She stabbed Muriel Goldman for discovering that she is the murderer of Stephanie and James Woods. She bludgeoned Derek Wilcox with a trophy as he had attempted to call someone for help. The blow to Derek caused him to fall off the veranda, so it appears more likely his actual cause of death was defenestration. She slit Priscilla's throat for seeing her with the knife and becoming hysterical. Her body was planted in Tucker's room, along with the blunt object used to strike Derek, in an attempt to frame Tucker for the murders & attempted to kill Lois to keep anyone from finding out she had killed the other victims.
