Arthur Gatter (1940 – 12 December 1990), nicknamed The Hammer-Killer of Frankfurt, was a German serial killer.

Life

Arthur Gatter was an electrician by profession and lived in Australia for a while. After returning to Germany, he worked in assembly. Since the 1980s, he was no longer able to work and trashed his apartment on Wilhelm-Leuschner-Straße. It is believed that his schizophrenia was already greatly advanced at this time. Even in his next residence in Bornheim, he behaved suspiciously. At times, he had to be examined in a clinic for psychiatry and psychotherapy in Haina.Elisabeth Lücke: Frankfurt's Dark Side: Spectacular Criminal Cases, Sutton Verlag, 2014, p. 79, {{ISBN|978-3-95400-470-6}}.

Murders

The murders occurred from 1 February to 22 May 1990 on the outskirts of Frankfurt.{{Cite book|title=Maintower Kriminalreport: Great criminal cases|publisher=hr-fernsehen.de|language=German}} Frankfurt at the time had around 2,400 homeless people staying in the city and especially in the greener areas.Elisabeth Lücke: Frankfurt's Dark Side: Spectacular Criminal Cases, Sutton Verlag, 2014, p. 77, {{ISBN|978-3-95400-470-6}}.

2 February 1990: a crime scene was found in Weißfrauenstraße. A security guard found the body of 43-year-old homeless man, Hans-Peter "Peterchen" S. at 5:00 AM.
7 February 1990: Another victim, 22-year-old Kurt Helmut H. was found with fatal head injuries. He was not a homeless person, therefore initially no connection to the first victim was established.
2 April 1990: At the bus stop at Rechneigrabenstraße. At 5:40, homeless man Helmut R. was found with severe head injuries which led to his violent death.[http://www.stadtgeschichte-ffm.de/de/info-und-service/frankfurter-geschichte/stadtchronik/1990 Stadtchronik FFM]
3 April 1990: Two victims were killed near the Eschenheimer plant.
9 April 1990: Helmut R. was murdered in Ostzeil.{{Cite journal|issn=0044-2070|title=The guy with the iron bar|author=Michael Reinhard|journal=Die Zeit: Wochenzeitung für Politik, Wirtschaft, Handel und Kultur, Hamburg|publisher=The Time|language=German}}
4 May 1990: 46-year-old Hans-Peter M.'s bloody corpse was found around 7:30.
5 May 1990: 60-year-old Engelbert G. and 42-year-old Nicola Z. died about 50 metres apart. A crime scene photo with a bloodstained park bench visualised the brutality of the act. This meant that three homeless people had been murdered within 24 hours.
20 May 1990: Brazilian native Anderson S. followed a man into a bush, supposedly to have sex with him. However, he was instead stabbed but managed to survive. The badly-injured man fled and collapsed on a park bench, where he was subsequently killed by the murderer.
22 May 1990: Heinrich O. became the Hammer-Killer's last victim. A local resident had witnessed the incident and alerted the police. Only 12 minutes after the murder, a suspect was arrested.

Investigation

The police reacted to the deaths on 3 April and founded the special operation "Berber" under Commissioner Karlheinz Wagner, and measures were taken.[https://www.welt.de/regionales/frankfurt/article13456102/Karlheinz-Wagner-geht-in-Ruhestand.html Karlheinz Wagner retires, Die Welt], June 28, 2011 For example, dolls were draped as potential victims on park benches and plainclothed officers were to lure the offender as "decoys". The police tried with surveillance technology (including stealth cameras in bird houses) to catch the culprit red-handed. However, the diffused parking lights and the inadequate camera technology were not enough to attract investigation-relevant images. Even a survey of dry-cleaning companies on whether blood-stained clothing has been delivered provided no results. In the homeless scene, the fear was reversed and the city put up additional shelters and left the subway stops open overnight, so that as few people as possible had to sleep on park benches.

On 11 April 1990, a homeless man said he saw a man approach a sleeping person with a blunt object. After a facial composite was made, a suspect was arrested in Gallus, but had to be released due to lack of evidence.

On 22 May 1990, Arthur Gatter was arrested in connection to the hammer murders. As the supposed murder weapon a metalwork hammer was secured, which he carried hidden in a plastic bag in the armpit. Through this instrument, the typical impression fractures or perforated structures in the skull came about, as determined in forensic medicine.{{Cite web |url=http://www.mdr.de/spur-der-taeter/spur-der-taeter-hammermoerder100.html |title=A Unique Murder Series: The Hammer Killer |access-date=31 July 2018 |archive-url=https://web.archive.org/web/20160725005701/http://www.mdr.de/spur-der-taeter/spur-der-taeter-hammermoerder100.html |archive-date=25 July 2016 |url-status=dead }} He systematically searched for victims on park benches and surprised them in their sleep. He watched them for a while, until he was sure he could do his job safely. For sneaking purposes, he wore low-noise rubber gloves. He struck with such force that blood splattered meters away.{{Cite web|title=bild der wissenschaft online - Heftarchiv|url=http://www.bild-der-wissenschaft.de/bdw/bdwlive/heftarchiv/index2.php?object_id=10095063|access-date=27 February 2015|language=German|archive-url=https://web.archive.org/web/20170227233341/http://www.bild-der-wissenschaft.de/bdw/bdwlive/heftarchiv/index2.php?object_id=10095063|archive-date=27 February 2017|url-status=dead}}

A psychiatric report which was made at the time attested him an insanity defense.Elisabeth Lücke: Frankfurt's Dark Side: Spectacular Criminal Cases, Sutton Verlag, 2014, p. 80, {{ISBN|978-3-95400-470-6}}. Before he could be taken to court, on 12 December 1990, Gatter hanged himself with a gauze bandage.
