On Saturday, March 12, 2005, 15-year-old Bart Oliver, a White male, was killed during a weekly Sabbath service for the Living Church of God held in a Sheraton hotel conference room in Brookfield, Wisconsin. The service was attended by about 50 to 60 people when a 44-year-old congregation member, Terry Ratzmann, entered and began shooting with a 9mm handgun, firing 22 rounds in roughly a minute and reloading once.

The attack killed seven people, including the church minister and his teenage son, and wounded four others before the shooter turned the gun on himself and died at the scene. Investigators reported that Ratzmann had been facing job troubles and had been upset by a sermon he heard two weeks earlier; no suicide note was found, and encrypted files were recovered from his computers.

If anyone attended that service or knew Bart Oliver and can share memories or information that might add to the record, please come forward.
