HOUSTON -- A jury has convicted a Houston cancer doctor of assault for poisoning her lover and colleague's coffee.
The decision was reached early Friday after nearly two days of deliberations.
Dr. Ana Gonzalez, 43, was on trial for poisoning Dr. George Blumenschein. Her family members were in court and wept as the verdict was read.
The sentencing phase of the trial is now under way. Gonzalez, who was a world-renowned breast cancer oncologist at M.D. Anderson, faces 20 years to life in prison.
Prosecutors told jurors that Gonzalez-Angulo was a devious and diabolical person who became obsessed with Blumenschein. They said the affair turned into a "fatal attraction" and she poisoned him with ethylene glycol after Blumenschein spurned her in favor of Evette Toney, his live-in girlfriend of 10 years with whom he was trying to start a family.
Jurors deliberated for about four hours over two days before reaching their verdict. Gonzalez-Angulo had no visible reaction after the verdict was read.
Blumenschein told jurors that he became sick Jan. 27, 2013, not long after he and Gonzalez-Angulo had been intimate, and that he immediately suspected his lover of spiking his coffee. Witnesses testified that Gonzalez-Angulo had access to ethylene glycol at the University of Texas M.D. Anderson Cancer Center where she and Blumenschein worked.
Gonzalez-Angulo's attorneys argued that other people, including Toney, might have been responsible for the poisoning, an allegation that Toney has denied. Toney says she and Blumenschein are working on their relationship.
The defense team also noted a prosecution expert's testimony that Blumenschein could have ingested the poison two days earlier.
The trial, which began Sept. 15, was filled with plot twists straight out of a soap opera, including prosecutors' claims that Gonzalez-Angulo lied about being attacked outside her home in an effort to get Blumenschein to leave his girlfriend. Prosecutors also said Blumenschein secretly recorded calls in which he tried to get Gonzalez-Angulo to confess to poisoning him.
Blumenschein said he delayed reporting his suspicions to authorities for fear that Gonzalez-Angulo would try to hurt him or Toney.
He told jurors he now has only about 40 percent of his kidney function.
The punishment phase of the trial began shortly after the verdict was read. Gonzalez-Angulo could face up to life in prison. She is also eligible for probation.
Dr. Marjorie Green, who worked with Gonzalez-Angulo, testified during the punishment phase via a recorded video that Gonzalez-Angulo had told her a few weeks after Blumenschein had been poisoned that "she was nervous because she had ethylene glycol shipped to her office."
