Do you have a source for that statement?

Although the total number of victims dispatched by a given killer is often in doubt, (e.g., homosexual Henry Lucas claimed that he killed 350), it appears that the modern world record for serial killing is held by a Russian homosexual, Andrei Chikatilo, who was convicted in 1992 of raping, murdering and eating parts of at least 21 boys, 17 women and 14 girls. The pathology of eating one’s sexual victims also characterized Milwaukee’s Jeffrey Dahmer in 1992. He not only killed 17 young men and boys, but cooked and ate their body parts.
The top six U.S. male serial killers were all gay:
• Donald Harvey claimed 37 victims in Kentucky;
• John Wayne Gacy raped and killed 33 boys in Chicago, burying them under his house and in his yard;
• Patrick Kearney accounted for 32, cutting his victims into small pieces after sex and leaving them in trash bags along the Los Angeles freeways;
• Bruce Davis molested and killed 27 young men and boys in Illinois;
• A gay sex-murder-torture ring (Corll-Henley-Brooks) sent 27 Texas men and boys to their grave; and
• Juan Corona was convicted of murdering 25 migrant workers (he “made love” with their corpses).
Lesbian Aileen Wuornos laid claim in 1992 to “worst female killer” with at least 7 middle-aged male victims. She singlehandedly topped the lesbian nurse team of Catherine Wood and Gwen Graham, who had killed 6 convalescent patients in Grand Rapids, Michigan.
