(Portland, OR) -- Eight bodies have been recovered in the Willamette River since April 1st. That includes two bodies that were located over the weekend. The Multnomah County Sheriff's Office says while that number is tragic, it's not unusually high. Most of those people died by accidental drowning or suicide, according to the Medical Examiner and investigators do not believe there is a connection between the cases. Authorities say water currents and temperature, along with more people enjoying river activities increases the likelihood remains will be found.
