Rignall eventually reported the incident to the police, and despite his being drugged, he managed to trace Gacy’s residence and spotted his Oldsmobile. This made the police decide to do a surveillance of Gacy’s home. Furthermore, the results from the hospital on Rignall’s case showed that he had a bleeding anus, a damaged face and liver due to the chloroform. Unfortunately, the Chicago Police found that Gacy’s suburban abode put him outside their jurisdiction, thus the pressing of felony charges became impossible, and the matter was settled when Gacy agreed to pay Rignall at least $3000 for the medical bills.
It wasn’t until Mrs. Elzabeth Piest, during the same year, filed a case for his missing son, fifteen year-old Robert. Robert had expressed interest iin applying for a local construction firm for a summer job, and he was reportedly referred by the local pharmacist to Gacy’s firm, the contractor that gave estimation for refurbishments in the shop. Gacy denied about Robert’s whereabouts, but the police later checked Gacy’s records and found that he had a sodomy case. Gacy denied any knowledge of it at all, and refused to come down to the precinct.
Without that much for a case, the police couldn’t detain him, but they put Gacy’s residence under surveillance. However, Gacy managed to put Robert’s corpse in the trunk of his car and dumped the young man’s remains in the Des Plaines river. The police finally got a search warrant for Gacy’s residence, but they only found a piece of receipt addressed to Robert Piest. That evidence wasn’t much to detain Gacy, but this didn’t stop the police surveillance. The discovery of Gacy’s killings was somehow initiated by Gacy himself.
He invited police for coffee in his home, and it was not long before the police smelled of something rotting. They ultimately discovered that the corpses of twenty-nine victims over the years were buried under Gacy’s house. They also found four bodies dumped in the Des Plaines river, including Robert Piest’s body. During Gacy’s trial, psychiatrists for defense stated that Gacy was suffering from “a mental illness that caused him to swing from periods of normalcy to intense psychosis”. On the other hand, the psychiatrists for the prosecution stated that Gacy had “a psychopathic or antisocial personality with sexual deviation”.
The prosecution stressed on Gacy’s sane everyday presentation of himself, and that he had shown no evidence of psychosis. Furthermore, the prosecution stated that it was impossible for Gacy to have suffered thirty-three isolated instances of psychosis that would have resulted in murder; John Wayne Gacy was guilty, and it was his morals that was distorted. John Wayne Gacy’s trial resulted to life imprisonment in 1980. David Berkowitz David Berkowitz instigated the largest manhunt in New York City which involved hundreds of detectives and police officers. Intially dubbed as the “.
44 caliber killer”, David Berkowitz eventually became known as the notorious “Son of Sam”, the serial killer who performed gunshot killings to a number of women in New York City. David Berkowitz is a son of a Jewish divorcee, who gave him up for adoption. Psychiatrists who examined him were interested in his past: Berkowitz has an above-average IQ but has very low self-esteem. He kept clippings of 1488 arson attacks, and he was always regarded as a loner, withdrawn, and a paranoid. He also had this enduring hatred for women. Berkowitz worked in a Postal Service in the Bronx, but this didn’t help him change his solitary disposition.
In November of 1975, Berkowitz took a month off from his job at the post office, locked himself up in his apartment, and covered his windows with blankets. He disposed all of his furniture except for a bare mattress where he had spent most of his time eating junk food and masturbating. In December of the same year, he started his attacks by killing two women with a knife. Later, he exchanged his knife for a . 44 Bulldog caliber. One night in July of 1976, he shot two women who were inside a parked car: Donna Lauria in the neck, and Jady Valenti in the leg.
Lauria was killed, and Valenti was seriously injured. Berkowitz waited until October 1976 to resume his attacks, and he did them again with women who were sitting inside parked cars. A month later, he shot two women walking home from the cinema, Donna Demasi and Joanne Lomino. Later on, he shot Christine Freund who was on a date with her boyfriend. These killings led to a massive manhunt by the New York City police force where a multi-unit taskforce was formed led by Deputy Inspector Timothy Dowd. This was regarded as the largest manhunt in the city’s history.
