There was a police car, ambulance and firetruck (the thing I actually heard) parked everywhere nearby*. No lights, no sirens (in retrospect, I realize they just don't seem to use those at night. Guess the night traffic here doesn't warrant it and I can't say I am unhappy about this.)
No idea what it was about, though. There were lots of people (firemen and women, mostly) standing around the apartment building across the parking lot from mine and a person in street clothes talking to one of them (or maybe a police officer - hard to tell in the dark).
Guess I will just have to live with the curiosity.
*the firetruck really was parked right outside my bedroom window. SOOOO glad there were no lights or sirens.
