user not logged in but still "who -a" shows a record

Hi All
I have script in my server to inform whoever logged in except me and root. Recently a user had logged in but i killed the session by informing the user. But somehow, the script still alerting me that he is logged in. When i check, the command to filter the user name "who" shows his name though his session was killed.

How to kill his (asapav) session (which is dead but may be exist in the process table) as to avoid receiving alerts? Ofcourse, there is no zombie processes too in process table.

Kill all processes of that user, and then check again, as
pkill -9 -u asapav
ps -ef | grep asapav
