The Clackamas County Sheriff released this timeline of events in the Town Center Mall shooting.
At 3:29 p.m. on Tuesday, Dec. 12, we received multiple 9-1-1 calls reporting an active shooter at Clackamas Town Center.
Our first unit arrived on-scene 1 minute later, at 3:30 p.m.
Once on scene, deputies initiated an "active shooter protocol" -- a technique developed to deal with precisely this type of threat. In this protocol, rather than waiting for a SWAT team to deploy, individual officers are trained to form up in teams as they arrive and move immediately to engage the threat. This involves officers from different agencies being thrown together on short notice. Law-enforcement personnel on-scene executed this protocol to the highest standard.
Personnel were well-prepared for this incident because they had practiced active-shooter techniques at Clackamas Town Center earlier this year.
At this writing, investigators believe the suspect moved through the mall in the following manner:
Prior to beginning his attack, the suspect parked his vehicle in the mall's south lot, near Macy's. He then moved north on foot through Macy’s towards the food court. He then opened fire, fatally wounding two victims. Crime Scene Investigators also found indications of additional bullet strikes throughout the food court area.
Next, the suspect is believed to have moved east -- past the Macy’s Home Store and into a service stairwell.
Moving down onto the lower floor of the mall, he continued east towards JC Penney’s, where he was found dead by responding law-enforcement personnel -- 22 minutes after the first 911 call.
At some point during this attack, the suspect wounded his third victim, Kristina Shevchenko, a juvenile. Shevchenko managed to exit the mall near REI, where law-enforcement personnel contacted her and began rendering medical assistance.
