如何在查询中计算两个不同的东西

I got this query:

$q = $mysql->query("
SELECT *, COUNT(`crimeDescription`) AS total_count 
FROM `crimes` 
GROUP BY `crimeDescription` 
ORDER BY COUNT(`crimeDescription`) DESC 
Limit 15") or die($mysql->error);

I also want to get the person who has had this crime issued most times against him (crimeIssuedTo)

Example:

1 | Grand Theft Auto | Most to: User_A | Total: 500
2 | Attempted Murder | Most to: User_C | Total: 453
3 | Assault          | Most to: User_D | Total: 451

How can I do that?

    How about something like the following:

    SELECT *, COUNT(*) AS total_count, 
    (
      SELECT p.Username 
      FROM crimes AS sc
      INNER JOIN players AS p ON p.ID = sc.crimeIssuedTo
      WHERE sc.crimeDescription = sm.crimeDescription
      GROUP BY sc.crimeIssuedTo
      ORDER BY COUNT(*) DESC
      LIMIT 1
    ) AS PersonWithMostOffenses
    FROM crimes AS sm
    GROUP BY sm.crimeDescription
    ORDER BY COUNT(*) DESC 
    LIMIT 15
