Controlled-environment facility resident pattern electronic communication detection systems and methods may employ a controlled-environment facility secure communication platform, an investigative data aggregation and analysis system, and/or the like. Controlled-environment facility individual resident outgoing electronic communication velocity is monitored. The individual resident outgoing electronic communication velocity may be the number of electronic communications placed by a controlled-environment facility resident, to telephone numbers and/or electronic communication addresses over a period of time. A sharp increase in outgoing electronic communication velocity for a particular controlled-environment facility resident over a relatively short period of time may be recognized and controlled-environment facility personnel of a controlled-environment facility in which the particular controlled-environment facility resident resides may be alerted that the particular resident is at risk of imminent danger, such as suicide, in response to recognition of the sharp increase in outgoing electronic communication velocity for the particular resident over the relatively short period of time.
