A prominent Houston doctor has been charged for allegedly poisoning her lover and coworker by spiking his coffee with a sweet-tasting chemical used in antifreeze and medical research.

Oncologist Doctor Ana Maria Gonzalez-Angulo allegedly did the coffee poisoning in her home to Dr. George Blumenschein, a doctor specializing in lung, head and neck cancers. She is charged with poisoning his coffee with deadly antifreeze.

Doctor Andulo claims she is innocent of poisoning her fellow doctor's coffee.  But after Blumenschein drank the coffee at her house, he was rushed to the emergency with renal failure, the loss of use of his kidneys.

When Blumenschein, a black coffee drinker, complained that his coffee tasted sweet, she told him she'd added Splenda and told him to finish it, after which she made him another cup. Blumenschein said both coffees tasted sweet.

Within four hours, he began experiencing slurred speech, poor balance and a loss of fine motor skills. He was taken to an emergency center, where he was found to have central nervous system depression, cardiopulmonary complications and renal failure. He later had to undergo dialysis.

A 24-hour urine test found crystals consistent with ethylene glycol poisoning, according to the complaint. It also said a county toxicologist concurred with the assessment.

 A toxicology report by a third expert indicated Blumenschein's acute severe metabolic acidosis "more likely than not" was due to ethylene glycol poisoning.

Ethylene glycol, a solvent and starting material for the synthesis of more complex molecules, is present in all M.D. Anderson laboratories, and Gonzalez-Angulo had access to the substance, investigators said.

After being arrested and charged, Gonzalez-Angulo is free on $50,000 bail. In the police report, her connection to Blumenschein is categorized as a "casual sexual relationship."

Gonzalez-Angulo's lawyer, Derek Hollingsworth, told the Houston Chronicle that she is "completely innocent."

"She is a distinguished citizen and scientist, and these allegations are totally inconsistent with her personal and professional life," Hollingsworth said in a statement.

Sounds a little fishy to me. Even if she is telling the truth, if she knew he didn't like his coffee sweet, why would she put Splenda in his drink?

Do you think she's lying and wanted to discreetly lose her lover?
