(SEATTLE) -- The father of the man who opened fire and killed five people across Seattle, and later killed himself after a citywide manhunt, says his son was a very private person who was "disgruntled."
"He was happy sometimes, but not really. He was kind of disgruntled," Walt Stawicki said about his son Ian Stawicki, who fatally shot himself after a killing spree on Wednesday.
Seattle's Harborview Medical Center confirmed that Ian Stawicki, who according to his father was unmarried with no children and had recently worked on a fishing processing boat in Alaska, died at 6 p.m. PDT Wednesday.
After the shootings began at approximately 11 a.m. PDT, when Ian opened fire at Cafe Racer Espresso in Seattle's University District, eventually killing four people, he killed a fifth random woman in a subsequent confrontation and stole her car.
Two victims died at the scene at Cafe Racer Espresso, while two more died later after being taken to Harborview Medical Center. People who were brought to the hospital had suffered gunshot wounds to the head, according to Susan Gregg, a hospital spokeswoman.
According to the Seattle Times, two of the victims at the cafe were Joe "Vito" Albanese, 52, who was killed along with best friend Drew Keriakedes, 45; the two men were in a band called God's Favorite Beefcake. The two other victims shot at the cafe have not yet been identified.
The newspaper reports that the only survivor of Wednesday's shootings is Leonard Meuse, who is currently out of surgery at Harborview Medical Center after being shot in the jaw and the armpit. Meuse is expected to survive.
Though it was unclear what prompted the cafe shooting, Ian's brother Andrew Stawicki said that his girlfriend said he was acting "kind of crazy" Wednesday morning, and she would not let him have a car.
Ian apparently had his mother's pickup truck on Wednesday; the family currently does not know where the vehicle is located.
