Investigators are reviewing surveillance footage from nearby businesses, traffic cameras and the Mountlake Terrace Transit Center after a woman vanished Monday morning.

Cheryl DeBoer was on her way to a work carpool when she texted her friend that she forgot her work badge and asked her friend to go on without her. Her friend said she would wait and asked how long. DeBoer said she would be 10 minutes late, but never showed up.

Her friend was no longer able to reach her by phone. Police say there hasn’t been any activity on her phone since.

Family members say previous reports that DeBoer planned to take a bus are incorrect; she only planned to carpool with her friend. Her car was later found near the Transit Center overflow parking, located in the 23400 block of 58th Avenue West.

Police call the disappearance suspicious. Now, family members and police are asking anyone who saw anything suspicious Monday morning near the Transit Center to report it.

“Somebody has to know something and we’re asking for anyone’s help,” Alicia Coragiulo, DeBoer’s niece, said during a press conference Wednesday night.

Her son and husband were too grief-stricken to appear at the press conference.

Cheryl DeBoer, a 54-year-old Mountlake Terrace resident, works at the Fred Hutchinson Cancer Research Center in Seattle, where she is a systems analyst at the Center for HIV/AIDS Research and Prevention.

Snohomish County Search and Rescue personnel and K-9 units searched the nearby Veterans Memorial Park. The search turned up no leads.

Anyone with any information or who may have seen anything suspicious Monday morning is asked to contact the Mountlake Terrace Police Department at 425-670-8260.
