(Portland, OR) -- A cemetery in Northwest Portland is suing a woman over her son's gravesite. Skyline Memorial Gardens says it sold the burial site to another family first before selling it to Paula Tin Nyo. Her 19-year-old son, Tyber Harrison, is buried at the site after he was hit by a car in 2016. The cemetery is trying to compel Tin Nyo to move her son's grave marker, a memorial bench, and a vault with some of his items inside.
