Rex Allen died on December 17, 1999, two weeks before his 79th birthday, in Tucson, Arizona, after he sustained fatal injuries when his caregiver accidentally ran over him in the driveway. Cremated, his ashes were scattered at Railroad Park in Willcox where most of his memorabilia are on display.
In 2003, Allan and his wife, Angela Herzberg, moved to Tennessee from California. On October 25, 2004, Angela Herzberg committed suicide after suffering from depression and migraines. Allan initially put his career on hold, but soon turned to music to deal with the loss of his wife.
