Robert Scott McCubbins didn’t have a lot of visitors.The 56-year-old veteran lived in a Hazel Dell apartment complex, where neighbors knew him as “Mr. Rob.” Down the street, at the Safeway grocery store where he was a regular, staff knew him and his service dog — a black Lab named Hooch.“He was a nice, quiet old man. He’s been there for years,” said Virginia Sorenson, a neighbor at Willow Creek Apartments. “None of us can remember anyone visiting.”She described McCubbins as having a slight build, dark scruffy hair and a beard. He wore a military hat and walked with a limp. He looked a little older than he was.“He’d walk his dog every day around the complex,” Sorenson said. He’d wave to everyone and stop to chat.Then he’d walk to Safeway, where the duo did the rounds. Everyone knew Mr. Rob and Hooch.“He was just a guy that I could tell didn’t have a whole lot of people around him,” said Lynn Goss, an employee at the grocery store.McCubbins was estranged from his family, who lived in Illinois. When he was discovered at 9:15 a.m. on Nov. 26, dead in his apartment, first responders suspected he’d been there a few days. His death certificate listed the cause as complications of chronic ethanol abuse with dilated cardiomyopathy, liver with steatosis and fibrosis — he died from drinking.
