HOUSTON - A doctor in Houston is charged with poisoning coffee she served her lover, according to a report.
The ABC affiliate in Houston reported the accused as Ana Marie Gonzalez-Angulo, a breast cancer oncologist at the University of Texas M.D. Anderson Cancer Center.
She allegedly poisoned a co-worker she was dating, Dr. George Blumenschein, with a substance found in antifreeze called ethylene glycol, reported KTRK.
Blumenschein, who generally drinks his coffee black, reportedly asked Gonzalez-Angulo why it tasted so sweet.
She told him that she put Splenda in it, the report said.
After asking for a new cup, she reportedly told him to finish the one she gave him first. The second cup tasted just as sweet, reported KTRK.
Within four hours of drinking the coffee, Blumenschein reportedly began to slur his speech and had poor balance.
Blumenschein was later taken to a hospital where doctors learned the amount of the substance he ingested could have killed him, KTRK reported.
He was "experiencing central nervous system depression, cardiopulmonary complications and renal failure," the report said. He remains under a doctor's care.
Gonzalez-Angulo's lawyer told KTRK that she is "completely innocent." She's due in Harris County District Court on July 10 to be arraigned.
