Law Enforcement (LE) not cross reporting the critical incident was influenced by law enforcement's perception of the murder/suicide incident and that child protection did not need to be involved given the suspected perpetrator was deceased.  Further impacting the child protection report not being made was varied cross reporting practices exist by the multiple law enforcement jurisdictions within the county based upon thee populations within each jurisdiction.  For example, if an incident like this occurs in Champlin, it is likely not going to be reported to CP.  However, if the incident occurs in Minneapolis it is likely going to be reported to CP.  
Cross reporting between the local agency and LE is further impacted by the changes in relationship that occur between CP and LE over the years.
