Hello,

As the DML is happening on CaseComment object ( you are inserting a new CaseComment), we need a trigger on CaseComment object. It can be as simple as below ( assuming you don't have any other trigger on CaseComment).
  
trigger CaseCommentTrigger on CaseComment (after insert) {
    List<Case> casesToUpdate = new List<Case>();
    for(CaseComment cc: Trigger.New){
        Case caseToUpdate = new Case(Id=cc.ParentId, Latest_Comment__c=cc.CommentBody);
        casesToUpdate.add(caseToUpdate);
    }
    update casesToUpdate;
}
Please try it and let me know how it goes. Thanks!
