A suspect has been arrested in connection to the 2009 homicide of Portland assistant federal public defender Nancy Bergeson. 

The suspect is 28-year-old Christopher Alexander Williamson. He was arrested Friday, Jan. 19, by Portland police.

Bergeson, 57, was found deceased in her home on Nov. 24, 2009. An autopsy revealed that Bergeson died of “homicidal violence,” according to the Portland Police Bureau. At the time, there were no clues pointing to any suspects or circumstances surrounding Bergeson’s death.

“Even though it has been 9 years, Nancy continues to have a tremendous presence and positive influence in the lives of many people. Her friends and family appreciate the tenacious work of law enforcement; for the first time in many years, we carry a hope that there will be answers and justice,” said Bergeson’s family in a statement.

The Portland Police Bureau and the Multnomah County district attorney’s office investigated Bergeson’s homicide for nine years, leading to Williamson’s arrest.

Lisa Hay is the federal public defender for Oregon. She worked with Bergeson for a decade.

“We appreciate what the Portland police have done following the case and that they have collateral evidence that they believe justified an arrest,” said Hay.

Williamson was booked on one count of murder and will be arraigned Jan. 22 in Multnomah County Court. 

The investigation is ongoing.
