This systematic review examined the evidence on factors influencing the flow of homicide, from suspicious death to imprisonment. Bibliographic databases and thesis portals were searched. The total number of hits was 15,986, of which 15,830 were irrelevant, 35 did not include a quantitative sample, 26 did not focus on homicide, 18 did not present flow data, and for seven there was no full text available. The remaining 70 papers were analyzed. With the exception of one, no study presented a complete longitudinal flow. Results indicated that both legal and extralegal characteristics influence the likelihood of cases to drop out. Aside from a first mapping of homicide case flows, future research should explore false positives and false negatives, to come to a first understanding of funnel selectivity in homicide cases.

这项系统的审查研究了从可疑死亡到监禁影响杀人案流向的各种因素的证据。搜索书目数据库和论文门户。命中总数为15986，其中不相关的是15830，35没有包括定量样本，26没有关注杀人，18没有提供流量数据，还有7没有全文。其余70篇论文进行了分析。除一个例外，没有研究提供完整的纵向流动。结果表明，法律特征和法外特征都影响案件退出的可能性。除了对凶杀案件流进行首次制图外，未来的研究应探索假阳性和假阴性，以初步了解凶杀案件中的漏斗选择性。
