Diana Lovejoy, 45, fainted in court after she was found guilty of a conspiracy charge as well as attempted murder.
Lovejoy was wheeled out by paramedics and taken to a nearby hospital, FOX 5 San Diego reported.
The jury also found gun instructor Weldon McDavid Jr. guilty of attempted murder and assault with a deadly weapon for his role in the plot.
Lovejoy and McDavid planned the crime after meeting at a gun range where she was taking lessons, and contacted her ex-husband Greg Mulvihill on Sept. 1, 2016 while posing as a private investigator claiming to have information on his estranged wife, according to prosecutors.
McDavid instructed Mulvihill to go to a remote dirt road where he could pick up a package containing materials related to Lovejoy, prosecutor Jodi Breton told jurors. Mulvihill and a co-worker, Jason Kovach, drove to the area together to look for a package taped to a power pole.
Kovach testified that they saw some rustling in the bushes, then noticed what looked like a person lying down with a rifle pointed at them. The witness said shots rang out, and he and a wounded Mulvihill took off running.
Authorities determined the phone used to call Mulvihill was purchased by Lovejoy, and feces found in the bushes at the scene of the shooting were traced to McDavid.
McDavid’s attorney, Ricky Crawford, said his client was a trained marksman and retired Marine who fired his rifle only after he heard someone yell “I have a gun!”
“If Weldon McDavid wanted to kill someone with his skill set, he would have done so,” Crawford told the jury. “That was not his intent.”
Brad Patton, Lovejoy’s attorney, said his client had taken out a temporary restraining order against Mulvihill because she claimed he was abusing her and their son.
After the restraining order elapsed, Lovejoy still had concerns about her estranged husband but “at no time was there a discussion/conspiracy to murder her husband,” Patton told the jury.
