Andrei Chikatilo
Chikatilo followed the investigation carefully, reading newspaper reports about the manhunt for the killer which had begun to appear in the news media, and keeping his homicidal urges under control. For almost a year following the August 1985 murder of Irina Gulyaeva, no further victims were found in either the Rostov or Moscow Oblasts whose bodies bore the signature mutilations of the unknown murderer. Investigators did tentatively link the murder of a 33-year-old woman named Lyubov Golovakha—found stabbed to death in the Myasnikovsky District of Rostov on 23 July 1986—to the investigation, although this was solely upon the basis that the killer's semen type matched that of the killer they were seeking, that the victim had been stripped naked prior to her murder, and that she had been stabbed in excess of 20 times. The victim had not been dismembered or otherwise mutilated, nor had she been seen near mass transportation. Because of these discrepancies, many investigators expressed serious doubts as to whether Golovakha's murder had been committed by the killer they were seeking.
