Police say a driver who may have been under the influence of alcohol or drugs struck four pedestrians Monday, killing two and critically injuring two others, including an infant.
Seattle police spokesman Jeff Kappel said in addition to the infant, a woman in her 20s was also badly hurt. They were taken to Harborview Medical Center with life-threatening injuries.
Fire officials say the infant required CPR and the woman suffered a head injury. No details were immediately available about the two people who were killed. They were pronounced dead at the scene.
The accident happened shortly after 4 p.m. in a residential neighborhood in North Seattle. Kappel said the driver of the vehicle was being investigated for suspicion of driving under the influence of alcohol or drugs.
Kappel said detectives from the police department's Traffic Collision Investigation Squad were assisting with the inquiry.
"This remains an active incident," Kappel said in a statement.
