Abort process from another one

[sbagatin]

Hi all,
I have a process (call process 1) that is running a timer. And another process that is a completely different process (process 2).

If a specific  event is coming into process 2 I want to abort process 1. How can I get the reference of process 1 in process 2 and then terminate it?
Thanks a lot.

Couldn't you have process 1 store its identifier (in your DB schema), then wait for a message; have process 2 look up the identifier for process 1 and send a message to the waiting process, then have the flow from the receive message event in process one flow to a terminate event?
