Jon Meis and other students stopped the gunman Thursday at Seattle Pacific University.
A 26-year-old suspect was apprehended following the shooting that left a 19-year-old man dead and two other young people wounded. Police say the quick action by Meis likely saved lives.
The 22-year-old Meis is a dean's list electrical engineering student and is planning to marry his girlfriend later this month. A post on the Seattle Reddit page says: "This is the wedding registry for the man who subdued the SPU gunman. You know what to do."
A voice message at a phone listing for his parents' house asks for privacy and prayers for the family of the man killed.
The bloodshed in Seattle marked the latest in a series of mass shootings at schools and other public places around the country in recent years that have renewed a national debate over gun safety and mental illness.
Two weeks ago, a 22-year-old man stabbed three people to death and fatally shot three others before taking his own life in a rampage across a college town near the University of California at Santa Barbara.
