KENNEWICK, Wash.-- Kennewick death investigation update. Kennewick police have finished investigating the deaths of the mother and son who were found with gunshot founds on Friday.

Police are considering the deaths to be suspicious. Jason Mertz, 27, and Ruth Mertz, 56, were found by police on West Grand Ronde Avenue on Friday just before 5pm.

Jason Mertz was dead when police arrived. Ruth was taken to Kadlec Regional Medical Center where she later died.

Police don't believe anyone else was involved. Kennewick Police Officer Tony Valdez says "two bodies were turned over to the Benton County Coroner's Office where they'll do their investigation with autopsies and toxicology. Then all the agencies will get back together and come up with a final update."

The Benton County Coroner says they're investigating the deaths as possible homicides or suicides.

An autopsy will be performed Monday.
