Denise Salmon Burditus, 50, died in her husband Tony’s arms Sunday night after a gunman armed with an arsenal of rifles opened fire on the crowd of 22,000 from a 32nd-floor window at the Mandalay Bay. The high school sweethearts had been married for 32 years in a relationship that Tony said “only grew stronger” over the years. They had two kids and four grandchildren, with a fifth on the way. Tony said he and Denise regularly traveled the country with the grandchildren. Tony described Denise as a person who “always had a smile on her face.”
