The former California firearms instructor who was convicted of attempted murder and conspiracy last November in a botched murder-for-hire plot of his lover’s husband says he regrets cheating on his wife more than the crime that put him in jail.

“It was totally unsatisfying,” Weldon McDavid told Dateline‘s Andrea Canning about his affair with 45-year-old Diana Lovejoy, who was also convicted of conspiracy and attempted murder of her now ex-husband Greg Mulvihill. “If I could only take back one thing, I would take that out of the equation.”

Asked if he wouldn’t take back shooting Mulvihill — who was struck by a bullet on his side, but survived — McDavid, 50, responded: “If there was only one thing I can take away I would take [sleeping with Lovejoy] away because I hurt my wife, and that means more to me than anything.”

McDavid is currently serving a sentence of 50 years to life at the California Institution for Men in Chino. His former lover, Lovejoy, was sentenced to 26 years to life in prison.

Lovejoy and McDavid plotted to kill Mulvihill in September 2016. At the time of the shooting, Lovejoy, a triathlete and software technical writer, was embroiled in a heated divorce and custody battle with Mulvihill.
