Ka-BOOM!

That's what the noise sounded like and then police cars came from every direction...

The police were in the parking lot across the street for a while and then eventually left.
Something happened but I have no idea what. I just heard a noise that sounded like a
dumpster exploding and then there were flashing lights everywhere.

UPDATE: My buddy, Tom told me that a stolen SUV t-boned a taxi at the corner of 8th
and Sycamore Streets killing the two people in the cab. That's the next block up from my
apartment. Scary stuff. You can read about the tragic accident here.
