Police say a man suspected of multiple shootings in Seattle shot himself on Wednesday as officers closed in. The Seattle Times identified the suspect as Ian Lee Stawicki, a 40-year-old Seattle resident. 
His brother, Andrew Stawicki, said, "It's no surprise to me this happened. We could see this coming. Nothing good is going to come with that much anger inside of you." 
Officers believe Stawicki was responsible for killing four people: three at a Seattle cafe, and one at a downtown parking lot as part of a carjacking. He is listed in critical condition at an area medical center.

What's your opinion? Is this period of violence in an otherwise tranquil city just an anomaly? Or is this what we can expect to see more of?
