The gunman allegedly told the man "Go back to your country." Police are investigating the shooting in Kent as a possible hate crime, according to CNN affiliate KIRO.
The victim is a US citizen, originally from India's Punjab province, Seattle-area Sikh community leader Jasmit Singh told CNN.
Singh said the man's family told him that he had been in his driveway Friday when a 6-foot man approached, asking something along the lines of "why are you cleaning your car?"
