SAN ANTONIO -

The woman who claims dermatologist Dr. Calvin Day sexually assaulted her spent her second day on the witness stand Monday.

Using a diagram she had drawn, the woman showed the jury the layout of a secluded room in Day's office prosecutors say he called the "Bat Room.”

That is where she said Day assaulted her on a Sunday morning visit on August 22, 2010.

When questioned about a call to Day the day before the alleged assault, the woman denied she knowingly called his private cell phone.

“Did you know when you called that it was Dr. Day’s cell phone?” asked defense attorney Jay Norton.

“Absolutely not,” the woman replied.

Day’s lawyers claim the woman gave inconsistent information when making statements to medical board and prosecutors.

In July 2011, Day’s medical license was temporarily suspended following a dozen other allegations of inappropriate sexual behavior by the doctor made by former patients and employees.

If he is convicted in the case now on trial, Day is facing a maximum punishment of 20 years in prison.

Testimony will continue on Tuesday in Judge Ron Rangel’s 379th District Court.
