join on multiple tables

I have the following two tables in a SQL 2005 database.

people
--------
person_id (PK)
first_name
mid_name
last_name
empl_id

multiple_sources
----------
source
person_id (This is a FK to people.person_id)


Here is what I want to accomplish;
Write a script (using C# and LINQ) to identify all the records in the people table having the same empl_id - basically a "group by on empl_id having count(empl_id) > 1". The output needs to contain all the columns in the people table. Now, I also need to (left) join the people table with the multiple_sources table and exclude all the person_id's that have multiple_sources.source of either a "D" or a "Z".

I want to schedule to script to run once a week and forward the output to a group of people in my organization for data cleanup.

Can someone please help me get started?
Thank you.

Hi IUAATech;

The following query will locate all people with the same empl_id and that the group is greater then 1.

Fernando
DataClasses1DataContext db = new DataClasses1DataContext();
 
var results = from p in db.peoples
              group p by p.empl_id into emplGroup
              where emplGroup.Count() > 1
              from g in emplGroup
              select g;
 
foreach (var empl in results)
{
    Console.WriteLine(empl.person_id + ", " + empl.first_name +
        empl.mid_name + ", " + empl.last_name + ", " + empl.empl_id);
}
