Confirmed to be in the Oregon Missing Person Database. This is a very concerning case, she left work, then her clothes she was wearing were found next to Willamette River.

Ironically, she was rescued from the same river in January 2016.   "call about 4:30 that a woman was seen in the Calapooia River headed toward the Willamette" witnesses first saw her on the Bryant Way bridge. She was rescued by the fire department and transferred to the hospital. They were unable to determine why she was in the river.

When spotted the fire department stated that, "not really swimming, just flailing to stay above the water."
