We now know who witnessed Donald Moeller's execution last month.
In all, 20 people watched Moeller die by lethal injection October 30.
Besides Becky O'Connell's mother, Tina Curl, and her husband Dave Curl, several people who worked Moeller's case back in the 1990s were in the death chamber including former Sioux Falls Police investigators Mike Larsen and Steve Nyhaug, and former Division of Criminal Investigation agent Fred DeVaney.
Federal Judge Lawrence Piersol, who allowed Moeller to throw out his final appeal, also witnessed the execution.
The only person in the death chamber on Moeller's behalf was his attorney Mark Marshall.
