THE DALLES, Ore. -

Testimony is nearing an end in an $18 million lawsuit brought by three women who allege a Columbia Gorge hospital and two executives didn't take action that could have prevented the crimes of an anesthesiologist now serving a 23-year term for sex abuse and rape.

Dr. Frederick Field pleaded guilty in September 2012 to abuse that authorities say spanned four years.

The trial is now in its third week. The Dalles Chronicle reports Judge Paul Crowley has told jurors to expect closing arguments on Monday.

Mid-Columbia Medical Center lawyers say the hospital couldn't act against Field because one victim didn't respond to inquiries, and a second recanted. When another victim came forward in 2011, law enforcement authorities asked the hospital not to tell Field he was under investigation.
