The trial of America's most infamous serial killers.
Dahmer dismembered and killed seventeen men. Dahmer's victims represented 14 different minority groups, with 9 of them being black. Dahmer said that his interest in a possible victim was based on the physical appearance of that person and not their ethnicity. These claims have been substantiated by anthropological examination of Dahmer's victims, which found a resemblance and suggested he was compelled psychologically by a specific anthropometric body type. Dahmer's victims were often sedated and then strangled to death. Additionally, he was involved in necrophilia and cannibalism with a few of his victims.
On January 30, 1992, in Milwaukee County Court, one of the most notorious serial murderers in American history, Jeffrey Dahmer, the Milwaukee Cannibal, stood trial for the 15 murders he perpetrated. His trial was presided over by Judge Laurence Gram. There was just one trial for all his fifteen cases. On January 13, at his trial, Dahmer admitted to 15 charges of murder but claimed insanity as an excuse for his actions. He claimed that because of his serious mental disorder, he felt compelled to murder his victims. Dahmer's legal team claimed at trial that their client lacked the criminal intent required to commit murder because of his mental condition.
The prosecution argued that Dahmer was not unable to understand the gravity of his actions or control his urges because of any mental illness. On the 8th of February, Fred Fosdal testified as a prosecution witness. According to Fosdal's testimony, Dahmer did not suffer from any mental illness or defect at the time of the killings.
On February 12, forensic psychiatrist Park Dietz, who was the second and final witness to appear for the prosecution, testified that he did not believe that at the time of committing crimes, Dahmer had any form of mental disease or defect. He said that there was enough proof that Dahmer planned in advance for each murder and that this was the reason why Dahmer's deeds were not the result of spontaneous behavior.
Four charges of attempted murder, two counts of conducting an indecent act with a corpse, and one offense of creating a danger by preserving body parts were all proven beyond a reasonable doubt by the jury, and he was sentenced to fifteen years of life imprisonment on February 17, 1992. Later, in 1978, Dahmer was convicted of killing again in Ohio and given a sixteenth-life sentence. In 1994, Dahmer was murdered in prison by another prisoner. The proceedings surrounding his prosecution were among the most widely publicized in the United States. Mental illness and its consequences on the criminal justice system were front and center throughout his trial.
