On December 27, 2006, 44-year-old Catherine Howe was shot and killed in her Scottsdale home in an attack carried out by her husband, Lee Howe. The violence began in a bedroom where Catherine was fatally wounded; Lee Howe then shot his 17-year-old stepdaughter, Meggie Le, and his 18-year-old stepson, Richard Le.

Richard Le confronted Lee Howe in the kitchen and, during that confrontation, killed Lee Howe, ending the attack. Meggie Le was taken to a local hospital but later died, bringing the known death toll to three; Catherine and Lee Howe were found dead at the scene. No arrests were made because Lee Howe died at the scene. The motive for the killings was not reported.

If anyone knew Catherine, Meggie, or the family and has information about the lead-up to that night, please come forward.
