Alexander Cambias Sr is a character from the soap opera All My Children, portrayed by Ronald Guttman.
Alexander Cambias Sr first faked his death (on August 29, 2003), but later turned out to be alive upon his return to Pine Valley and also the Satin Slayer, an extremely clever serial killer murdering the women of Fusion Cosmetics.
The story-line proved to be one of the most controversial in daytime, for the death of character Dixie Martin, a former longtime heroine of the series.
The women of Fusion were being murdered by a serial killer. It starts in December 2006 and has connection to Zach Slater and his late mother, Amelia. During February Sweeps 2007, it is revealed that the Satin Slayer is indeed Alexander Cambias, Sr., Zach Slater's father, who was thought to be dead. The poison that was used to murder/attack the victims is a drug which causes Ventricular tachycardia, also known as V-tach.
In late 2007, Alexander is put on trial, and is sentenced to a mental institution. It was unsure whether he was really insane or faking it. He is later shot and paralyzed by an unknown assailant.
On April 27, 2009, Alexander sends a story to Ryan Lavery, in which he claims that he did not kill Dixie. He only takes the blame for the other Satin Slayer deaths. Strangely enough, he was quoted as saying that six women died during the story-line, but this is likely a continuity error as the only ones who did were Simone and Erin. Danielle and Babe were both exposed to the drug, but survived and recovered.
