NORTH SEATTLE, Washington (CNN) -- A shooting at a Seattle cafe and an apparent carjacking left four people dead and two wounded Wednesday while police investigated whether the slayings were connected.
Three of the four were shot in a coffeehouse in the city's University District about 11am (1:00 this afternoon, Kansas time) and a woman died in the carjacking near downtown about half an hour later, police said. Two of the cafe victims were dead at the scene, while another died at a nearby hospital and two more were in critical condition, they said.
Investigators were looking for any connections between the two incidents, which happened about four miles apart, police spokesmen said.
"We're definitely in a dynamic situation right now," Deputy Police Chief Nick Metz told reporters. Investigators did not know whether the gunman knew any of the victims, he said.
Investigators released security camera images of the man they believe carried out the cafe shootings Wednesday afternoon. He appears to be about 30, with dark hair and a beard, and was wearing a light blue jacket and a dark shirt.
Witnesses to the second shooting told police a woman and man were arguing in a parking lot when the man pulled out a pistol and shot the woman in the head. He took off in a black Mercedes sport-utility vehicle, which was found around noon in a neighborhood a few miles southwest of downtown, police said.
Heavily armed police were using dogs to search the neighborhood around the cafe early Wednesday afternoon, neighbors said.
"The streets are blocked off, and there's tons of cops," said Joe Backus, the manager of a musical instrument shop next to Café Racer, where the shootings took place. Police told employees and customers to stay inside while the search was going on, he said.
Nearby resident Evan Hill said he could hear the gunfire from his living room.
"I counted four or five shots and somebody shouting, and I ran out to my balcony and called 911," Hill told CNN affiliate KOMO.
Hill called the cafe a "very mellow" venue that hosts artwork and musical performances.
"It makes you kind of angry that it would happen in a place like that," he said.
