Travel

This chapter examines offender travel as a critical variable in crime pattern analysis. Travel choices – including mode of transportation, distance, timing, routes, and frequency – can reveal consistency across incidents and provide valuable investigative leads. Offenders may rely on familiar travel routines, use rental or stolen vehicles, or exploit transportation systems to facilitate mobility, evade detection, and expand their offending beyond local jurisdictions. Travel behaviors also interact with victim routines, creating predictable points of risk in public and private spaces. Investigators analyze these variables through mapping, cell phone data, GPS and ANPR systems, transit records, and eyewitness accounts to reconstruct offender movement and assess opportunity structures. The case of the Felony Lane Gang illustrates how systematic interstate travel, combined with disguises and fraudulent check-cashing practices, allowed a mobile criminal enterprise to operate across multiple states. Recognizing habitual or adaptive travel patterns can support linkage analysis, inform suspect prioritization, and guide proactive interventions to disrupt serial offending.
