Sunday afternoon CPD was again asked to assist county, state and other law enforcement entities. Given the proximity of the incident to Chapman city limits Chapman law enforcement and administration decided it was prudent to remind Chapman residents to ensure normal safety processes were in place. Lock doors, turn on lights, report unusual or suspicious activities or individuals.

County officials have released CPD personnel following efforts to locate individuals involved in the incident. All CPD personnel have returned to regular duties.

Details regarding the incident, individuals involved and other details have not been provided to Chapman city administration. Of course normal safety and security processes remain prudent.
