Delete Contact with AfterSubmit

I have an AfterSubmit function that runs when we get a new lead from our website. We have to create them as a Company, Individuals are not an option for our business practice.

I would like to delete the Contact that is created when the Lead is generated.

Can someone point me in the right direction? Here is the AfterSubmit I am using right now.

 function CleanData_CustomerAfterSubmit(type)  {   if(type == 'create')   {      var thisRecord = nlapiLoadRecord(nlapiGetRecordType(), nlapiGetRecordId());    var FullName = thisRecord.getFieldValue('companyname');        //Create FullName array    FullName = FullName.split(" ");    var FirstName = new Array;    NameLength = FullName.length;    //Trap single name in Legal Name and pop vars    if(NameLength == 1)    {     Dear = "Please Enter Value for First Name";     myLastName = FullName;    }    else    { //run code normally     for(i=0;i<FullName.length-1;i++)     {      FirstName[i] = FullName[i] ;      var Dear = FirstName.join(" ");      }     var myLastName = FullName[FullName.length-1];    }    //set vars    thisRecord.setFieldValue('custentitydear', Dear);    thisRecord.setFieldValue('custentitylastname', myLastName);    var mySource = "8";    thisRecord.setFieldValue('custentity_source', mySource);    //record vars to record.    var recordId = nlapiSubmitRecord(thisRecord, true);
