REDDING, Calif. - The woman who had an out of state and over the phone relationship with Mark Duenas, testified today.
Mark is accused of stabbing his wife Karen Duenas to death in their Cottonwood home in May 2012.
Tuesday in court was the second time Annette Green had seen Mark since the 1970s.
The first time was during the last trial in July.
Green wiped away tears and choked up as she read to the jury the apology letter she addressed to both Mark and Karen.
In the letter Green apologized for the relationship.
Mark and Annette knew each other as teenagers in Shasta County in the 1970s but were never romantic.
When Annette moved to Idaho in 1977 with her family they lost touch but in 2011, through one of Mark's co-workers they started talking again.
Green testified the two shared pictures of their families, texted a few times a week and talked on the phone about once a week.
They said "I love you" a total of three times.
In May 2011, Karen saw phone records and confronted Mark about the relationship.
However Annette said he continued to talk to her on a secret phone.
Annette testified that Mark at one point said that for them to ever be together, "something bad would have to happen."
After time Annette said she began to feel morally wrong, she told her husband about the relationship and ended communication with Mark in January of 2012, but on her birthday in February Mark reached out again.
Dale Green, Annette's husband testified he told Mark to stop contacting his wife and sent two text messages to Karen making her aware of Mark's actions.
In a cross examination, defense attorney Ron Powell, pointed out the relationship had never been physical, that neither Annette or Mark had considered leaving their spouses.
Annette also said Mark at one point said, "he would need to be a better husband."
Also taking the stand was Shasta County Sheriff's Office Sergeant Brian Jackson.
Jackson was in charge of the investigation for 29 days.
Defense attorney, Powell questioned Jackson as to why he alerted the public so shortly after Karen's death that there was no need to worry and that everyone was safe.
In a re-direct, Jackson gave a laundry list of reasons as to why his investigators had deemed the situation isolated.
Jackson said they looked at indicators in the home, such as the lack of evidence of a break-in, the events leading up to the murder, such as there had been no reports of prowlers in the area.
Investigators took into consideration the geographic location of the home, the 911 call made, as well as Karen's history.
Jackson said she had no known enemies and there was no evidence of a burglary in the home.
The prosecution said they expect to conclude their case on Thursday.
