Following are new details on yesterday’s active-shooter incident at Clackamas Town Center — including victim names, suspect details, photos, event chronology, list of participating agencies and mental-health resources.

We can now release the names of the two individuals killed in this attack. They are:

Cindy Ann Yuille, age 54, a resident of northeast Portland and
Steven Mathew Forsyth, age 45, of West Linn

The third victim — Kristina Shevchenko, a juvenile — survived the attack and is now being treated for her injuries at OHSU’s trauma center. She is listed in serious condition at this writing.


We can now share the name of the suspect in this case: JACOB TYLER ROBERTS, born March 6, 1990.

A photo of the suspect is at right.

Based on evidence gathered thus far, it appears the suspect died of a self-inflicted gunshot wound.

Additional information about Mr. Roberts:

• During this attack, the suspect was armed with an AR-15 semi-automatic rifle.
• The rifle was stolen yesterday from a person known to the suspect.
• At the time of the attack, Roberts was wearing a load-bearing vest — NOT a bulletproof vest, as has been reported.
• He was also wearing a hockey-style face mask.
• We have not yet established how many shots Mr. Roberts fired during the attack, although we believe he was carrying a large amount of ammunition.

After the Sheriff’s Office identified Jacob Roberts as the suspect in this case, deputies executed search warrants on his home — located at 7324 SE 84th Avenue in Portland, Oregon — and on his vehicle, a 1996 Volkswagen Jetta found in the Clackamas Town Center parking lot. Results of these search warrants are not being revealed at this writing.

At this writing, investigators have not determined a motive — but it appears that there was no prior relationship between the suspect and his victims.

At 3:29 p.m. on Tuesday, Dec. 11, 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.

It is the Sheriff’s Office’s understanding at this writing that Clackamas Town Center will be closed at least through the end of the day today (Wednesday, Dec. 12). Check the mall’s website,, for additional details on when the mall will re-open — as well as mall personnel’s plans to return personal items abandoned by shoppers during the incident.

After the mall opens again for business, the Sheriff’s Office and mall personnel are planning for extra patrols.

UPDATE w/ NEW NUMBER: Any witnesses should now call our Tip Line (503-723-4949) to make reports.

The Sheriff’s Office would like to thank all of our local, state and federal law enforcement and emergency-services partners for their extraordinary efforts in this case. Several neighboring jurisdictions — including Oregon City and Woodburn — made the decision to send all of their on-duty officers to the scene.

Even after it was determined the suspect was deceased, this extraordinary level of cooperation and support continued — allowing the Sheriff’s Office to move ahead rapidly with this investigation.

The Sheriff’s Office would also like to acknowledge Clackamas Town Center for their prompt and effective response to this crisis. By having a plan in place and implementing it in a timely manner, they helped protect the lives of their customers and employees.

Participating agencies in this incident response included:

Police officers from Portland, Milwaukie, Gladstone, Oregon City, Canby, West Linn, Lake Oswego, Molalla, Woodburn and Sandy

Oregon State Police
Portland Transit Police
Clackamas Fire District #1
The Portland CSI and Oregon State Police crime laboratories
