kill a screen (but not all screens)

I have multiple screens running on an Ubuntu server that are initiated as:

screen -dmS screen1 cmd
screen -dmS screen2 cmd
etc...

And I need to kill one screen, but not all of them. What is the correct command to kill a single particular screen with its name? I've read through the man pages but I can't seem to find the command I am looking for.

Also I want to write this command into a bash script so I can't simply screen -r screen1 then press Ctrl+X as I normally would.

• If you do a screen -list, you'll notice that each screen name begins with a number, which is the PID of the screen:

   $ screen -list
  There are screens on:
          12281.pts-1.jonah       (12/21/2009 07:53:19 PM)        (Attached)
          10455.pts-1.jonah       (12/19/2009 10:55:25 AM)        (Detached)
  2 Sockets in /var/run/screen/S-raphink.
  

  From there, just send a KILL signal to this specific PID:

  $ kill 12281
  

  and it will kill the specific screen.

  BassKozz : this won't work because I am running it from a bash script, and I rather not have to pull the PID from screen -list that matches the correct screen... defraagh's answer above worked like a charm. Thanks thou.

  Raphink : Ok, good that defraagh had a perfect solution for it.

• From the man page :

     -X   Send the specified command to a running screen  session.  You  can
          use  the  -d or -r option to tell screen to look only for attached
          or detached screen sessions. Note that this command  doesn't  work
          if the session is password protected.
  

  You can do :

          screen -X -S <sessionid> kill
  

  BassKozz : PERFECT!!! Thanks defraagh, musta missed that in the man.

  Raphink : Good to know :-)

• defraagh's solution doesn't work for me, however I can kill the screen session using Raphink's idea:

  screen -list get the process ID

  kill -9 PROCESSID

  screen -wipe SESSIONID
