In 2001, the magazine Elm Street published an article in which it implied that forensic evidence proved that Tammy's death was not an accident and that her sister had deliberately administered an overdose of Halothane. The magazine described Karla as a "malignant narcissist" who was so incensed by her fiancé's attraction to her sister that she took steps to remove Tammy from his affections permanently. Implications of Karla Homolka's plea bargain On February 26, 1993, the defence lawyer and the Crown began negotiations on a 10-year sentence for Karla in exchange for her testimony and full disclosure of all crimes. At the time of the negotiations, the role she and Bernardo had played in Tammy's death was not known. When she was admitted for psychiatric assessment in March 1993, Karla confessed in a letter to her parents about her involvement in Tammy's death. When the plea agreement was finalized, the initial 10-year sentence was still intact, with two years added for Tammy's death. Karla was officially sentenced to 12 years on July 6, 1993. On July 20, 1993, Tammy's body was exhumed. Inside her casket was a wedding invitation for Karla and Bernardo's wedding, as well as some notes. Other members of the Homolka family asked that the items be removed before Tammy's re-interment.
