20.500.12556/DKUM-76016 Police response to homicide crime scenes testing the effect of the number of police officers and investigators responding to an active crime scene on the arrest success rate Odziv policije na kaznivo dejanje umora testiranje vpliva števila policistov in kriminalistov, ki so se odzvali na storjeno kaznivo dejanje, na stopnjo uspešnosti odvzema prostosti Purpose: The purpose of this study is to investigate the effects that the first responders (police officers and investigators) have on the arrest success rates at homicide crime scenes. It attempts to determine whether or not increasing the number of officers (e.g., first line responders), and investigators responding to a homicide crime scene increases the arrest success rate, which contributes on the overall homicide clearance rates.Design/Methods/Approach:Using archived administrative data that were originally collected by the Phoenix Police Department, and sponsored by the United States Department of Justice, this study analyses 532 investigative reports. The types of cases analysed in this study are homicides crime scenes, which includes homicide victims and survivors. Findings: The findings in this study show that for every additional officer added to the number of police officers responding to the crime scene the arrest success rates increased by 8%, and for every additional investigator added to this first response, the arrest success rates increased by 24%. The number of witnesses and victims present at the crime scene did not have a significant effect on the arrest success rate of homicide cases.Research Limitations/Implications: This study is limited to examining the effects of the number of officers and investigators have on homicide clearance rates. It does not account for the limited departmental resources and their effects on the homicide arrest rates or clearance rates. Also, this study does not include factors that do not solely depend on the police response to homicide crime scenes (i.e., factors that the offenders have control over).VARSTVOSLOVJE,Journal of CriminalJustice and Security,year 21no. 2pp. 101‒114 102Practical Implications: The methods that police use to respond to and investigate homicide cases can determine the outcome of a case. Depending on how the police decide to respond, ultimately increase or decrease the effectiveness of making an arrest or salve a homicide case. An increase in the arrest rate, by definition, results in an increase in the clearance rate of homicide cases. Thus, the study findings touch base on the importance and the role of the number of first line responders and investigators have on homicide arrest success rates. Originality/Value: This is the first study that has examined the effects of first responders on homicide arrest rates. Namen prispevka: Namen študije je proučiti vpliv, ki ga imajo na stopnjo uspešnosti odvzema prostosti policisti in kriminalisti, ki se na kaznivo dejanje umora odzovejo prvi. Avtor poskuša ugotoviti, ali povečanje števila policistov in kriminalistov, ki se prvi odzovejo na kaznivo dejanje umora, poveča stopnjo uspešnosti odvzema prostosti, kar vpliva na stopnjo preiskanosti. Metode: V študiji so uporabljeni arhivirani administrativni podatki, ki jih je zbrala policija iz Phoenixa, njihovo uporabo pa je omogočilo Ministrstvo za pravosodje Združenih držav Amerike. V študijo je vključenih 532 preiskovalnih poročil kaznivih dejanj umorov in poskusov umorov. Ugotovitve: Ugotovitve študije so pokazale, da se je z vsakim dodatnim policistom na kraju kaznivega dejanja stopnja uspešnosti odvzema prostosti storilcu povečala za 8 %, z vsakim dodatnim kriminalistom pa za 24 %. Število prič in žrtev na kraju kaznivega dejanja pa na stopnjo uspešnosti odvzema prostosti v primerih umora ni imelo vpliva. Omejitve/uporabnost raziskave: Študija je omejena na proučevanje učinkov števila policistov in kriminalistov na stopnjo preiskanosti umorov. Študija ne upošteva omejenosti virov, s katerimi se sooča policija, in njihovega vpliva na uspešnost reševanja umorov in stopnjo odvzema prostosti. Študija prav tako ne vključuje dejavnikov, ki niso odvisni samo od odziva policije na storjeno kaznivo dejanje umora (npr. dejavnikov, nad katerimi imajo nadzor storilci). Praktična uporabnost: Metode, ki jih policija uporablja pri odzivanju in preiskovanju umorov, lahko vplivajo na izid primera. Učinkovitost odvzema prostosti ali preiskovanja umora se bo povečala ali zmanjšala glede na odziv policije. Povečanje uspešnosti stopnje odvzema prostosti, pomeni tudi povečanje stopnje preiskanosti. Ugotovitve študije torej izpostavljajo pomembnost in vlogo števila policistov in kriminalistov, ki se prvi odzovejo na storjeno dejanje, na stopnjo uspešnosti odvzema prostosti v primerih umora. Izvirnost/pomembnost prispevka: To je prva študija, ki je preučila učinke števila oseb, ki se prve odzovejo na storjeno kaznivo dejanje umora, na stopnjo uspešnosti odvzema prostosti. policija odziv policije preiskovanje stopnja odvzema prostosti umori stopnja preiskanosti true true true Angleški jezik Slovenski jezik Znanstveno delo 2020-04-07 10:38:40 2020-04-07 10:38:41 2022-08-09 12:01:49 2020-04-21 03:12:20 2019 0 0 str. 101-114 št. 2 Letn. 21 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 343.98 99492352 3788266 1580-0253 URN:SI:UM:DK:NJ4YZIBW https://www.fvv.um.si/rv/arhiv/2019-2/01_Avdija_rV_2019-2.html 1 https://dk.um.si/Dokument.php?lang=slv&id=141346 https://www.fvv.um.si/rv/arhiv/2019-2/01_Avdija_rV_2019-2.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=141167 RAZ_Avdija_Avdi_S._2019.pdf RAZ_Avdija_Avdi_S._2019.pdf 1 487B33790B40CEEB49342F3119724AC1 5f2133ee09697a3012db4f582e836dfacd8f61026f933173b44cff55f3e17a01 4364f3da-7c11-11eb-bb7a-00155d0001ca 20.500.12556/dkum/4d6cb7c3-a2ef-484a-a348-dd23a97dec7f https://dk.um.si/Dokument.php?lang=slv&id=141345 Fakulteta za varnostne vede Varstvoslovje 0 0 0
