Lisa Patterson, who ran Robert Patterson Hardwood Floors with her husband, Bob Patterson, was one of the 58 people killed during the shooting in Las Vegas on Oct. 1.

“My wife did everything for our company, from bookkeeping to returning calls to collecting checks, estimating and working with me doing the hardwood floors,” Patterson told People Magazine.

Lisa was 46 years old and was the mother of a 19-, 16- and 8-year-old. Patterson met Lisa when she was 18, and they married seven years later.

“[She] was the most beautiful thing,” he told People. “She had such a great smile. She was such a great mother. I don’t know what I’m going to do.”

A GoFundMe account has been set up to receive donations for the family.
