RT Article T1 One “Two” Many: An Examination of Solo Perpetrator Versus Team Perpetrator Serial Homicides JF Homicide studies VO 26 IS 2 SP 176 OP 198 A1 Chai, April Miin Miin A2 Yaksic, Enzo A2 Chopin, Julien LA English YR 2022 UL https://krimdok.uni-tuebingen.de/Record/1800608705 AB The current study examines the offender, victim, and crime characteristics between solo perpetrators and team perpetrators of serial homicide. Cases on 1,137 solo perpetrators and 254 team perpetrators were collected from the Consolidated Serial Homicide Offender Database. Results showed team perpetrators were more likely to be older than those who committed serial homicides alone. Offenders who never confessed their crimes were less likely to participate in teams. In terms of victim and crime characteristics, team perpetrators were more likely to target employees or customers, have a lower victim count, and were more likely to exhibit sadistic behaviors compared to solo perpetrators. Theoretical and practical implications from this study are discussed. K1 team homicide K1 serial homicide K1 multiple perpetrators K1 Co-offending DO 10.1177/10887679211060030
