PORTLAND, Ore. (AP) — Authorities have identified the person killed in a shooting early Saturday in downtown Portland, Oregon, as an 18-year-old woman who had graduated from high school last month. Portland Police said Monday that Makayla Maree Harris was killed in what is believed to be a drive-by shooting. Relatives told The Oregonian/OregonLive that she had graduated from Grant High School in early June and was the youngest in her family with six siblings. Harris was one of two people killed in four different early morning shootings Saturday in Portland that also injured multiple people. Oregon’s largest city has seen gun violence and associated homicide rates soar in the past six months.
