HI THERE, ED. >> GOOD MORNING, CHRISTINE. DR. ANA MARIA GONZALEZ-ANGULO HAS BEEN CHARGED WITH AGGRAVATED ASSAULT AND PUT ON LEAVE. SHE IS A BREAST CANCER SPECIALIST RESEARCHING THE MOST AGGRESSIVE FORMS OF THE DEADLY DISEASE AT THE MD ANDERSON CANCER CENTER IN HOUSTON. SHE WAS FEATURED IN THIS VIDEO HIGHLIGHTING A DAY IN THE LIFE OF A BREAST CANCER DOCTOR AT ONE OF THE MOST RESPECTED HOSPITALS IN THE COUNTRY. >> ONE OF MY AUNTS DIED WITH LUNG CANCER WHEN SHE WAS 35 AND I WAS 10 SO THAT WAS WHEN I MADE MY DECISION THIS IS WHAT I WANTED TO DO. >> Reporter: WHICH MAKES THE ALLEGATIONS SWIRLING AROUND HER MORE STUNNING. HOUSTON POLICE INVESTIGATORS SAY SHE TRIED TO POISON HER LOVER, GEORGE BLUMENSCHEIN. A FELLOW CANCER DOCTOR AT MD ANDERSON AS WELL. ACCORDING TO COURT RECORDS BACK IN JANUARY, GEORGE BLUMENSCHEIN WAS BEHIND THESE GATES AT THE HOME OF ANA MARIA GONZALEZ-ANGULO. ACCORDING TO THE RECORDS, SHE MADE HIM A CUP OF COFFEE, HE STARTED DRINKING IT BUT TOLD HER IT TASTED TOO SWEET. SHE TOLD HIM FINISH THAT AND SHE'D PUT SPLENDA IN IT AND MAKE ANOTHER ONE. HE DRANK BOTH CUPS OF COFFEE. 16 HOURS LATER HE WAS IN THE EMERGENCY ROOM. BLUMENSCHEIN STARTED LOSING HIS BALANCE, SUFFERED SLURRED SPEECH AND LOSS OF MOTOR SKILLS. ACCORDING TO THE COURT RECORDS, DOCTORS FOUND ETHYLENE GLYCOL IN HIS SYSTEM A POTENTIALLY DEADLY CHEMICAL USED IN ANTIFREEZE BUT MD ANDERSON OFFICIALS TOLD INVESTIGATORS IT'S A CHEMICAL COMMONLY FOUND IN LABS AT THE CANCER CENTER. DEFENSE ATTORNEY MARK GERAGOS SAYS IT COULD BE A TOUGH CASE TO PROVE IN COURT. >> WHAT YOU ALWAYS HAVE TO TAKE A LOOK AT WHAT THE PROSECUTORS WILL ALWAYS LOOK AT IN A CASE LIKE THIS IS THE MOTIVE. WHY DID SOMEBODY WANT TO DO IT AND WHY DID THEY WANT TO DO IT IN THIS WAY AND RULE OUT OTHER ENVIRONMENTAL FACTORS. THAT'S WHERE THE DEFENSE IS ALWAYS GOING TO GO. WAS THERE A MOTIVE? WOULD SOMEBODY HAVE DONE THIS, DO THEY HAVE THE CHARACTER TO DO THIS. >> Reporter: A LAWYER FOR GONZALEZ-ANGULO SAYS SHE'S "COMPLETELY INNOCENT," AND THESE ALLEGATIONS ARE "TOTALLY INCONSISTENT WITH HER PERSONAL AND PROFESSIONAL LIFE." NEIGHBORS AROUND HER GATED HOME SAY SHE IS A QUIET WOMAN WHO KEPT TO HERSELF. GEORGE BLUMENSCHEIN SURVIVED BUT HE'S SUFFERED SEVERE DAMAGE TO HIS KIDNEYS, EVEN NEEDING DIALYSIS TO TRY AND REPAIR THE DAMAGE. AND THE DOCTOR'S ATTORNEY ALSO TELLS US THEY'VE HAD SEVERAL MEETINGS WITH PROSECUTORS. THE DEFENSE ATTORNEY SAYS THEY BELIEVE THE POLICE JUMPED THE GUN AND THEY'RE HOPING
