It is harder than one might expect to call the emergency line in a city you aren't in.
First I called local 911 figuring they would connect me. They took awhile, then finally found a number, transferred me, the line went dead.
Then I looked up Chicago emergency number, but all they had was 911, so I called the non-emergency number.
Then I waited on hold for awhile.
Then I talked to a lady. She got the info from me.
Now I am on hold again while she contacts the correct local police dept.
