ARDMORE, Okla. -- Riveting testimony and details of a love triangle pushed to the breaking point. The James Eric Parker trial got underway on Friday.
We are learning more about the events that investigators say may have led to murder.
On Friday morning, the state's star witness, Kim Gilbert, was called to the stand, and delivered at times emotional testimony.
She described in detail her relationships with James Eric Parker and Danny Watterson, both of whom worked with her at a local tire plant.
She talked about how her then-husband Parker, first found out about her affair with Watterson by going through her cell phone records and later confronted her at knife-point in a locked bedroom and threatened her.
When asked to describe the experience, Gilbert said in her testimony that she was “terrified” and secretly dialed 911 for help, letting Parker think she was calling in sick to work instead.
On cross-examination, she admitted receiving at least one telephone call from Watterson the week she married Parker in Las Vegas.
When asked why she went through with the marriage despite her secret concerns about Parker's alleged violent tendencies, she replied "out of obligation...to my kids…and to him..."
Prosecutors asked why her numerous attempts to leave Parker after their marriage were unsuccessful.
"Because he had found me, he wouldn't willingly let me go if I wanted to," Gilbert said.
Gilbert later testified about the night Watterson was killed, saying she had gone to his home so they could watch movies together. Gilbert told the jury she heard a pop, glass shattering, and looked over her shoulder to see Parker standing outside the window with a gun in his hand.
Kim Gilbert then said she never saw Watterson move again.
Gilbert says she was in love with the victim, Mr. Watterson, and broke down on the stand a few times describing how she tried to leave her husband.
She also recalled her version of events in the 48 hours following the killing.
