Police said both were found with apparent gunshot wounds at the house where they lived in the 3000 block of Willow Ave. in Edgemere. Police would not elaborate on the circumstances of their death, but said they were killed following a barricade situation that arose from a “family dispute.”Garrison, who survived a traumatic brain injury in an accident in 2008, was remembered as a warm and welcoming presence at Robbie’s Bar and Restaurant in Sparrows Point, an establishment she ran with her father. Friend Sarah Jaskulski remembers how when her own daughter needed to sell Girl Scout cookies, Garrison insisted that she come sell them at the bar — they’d make her a top seller.
