Christianson, 20, is accused of kidnapping his girlfriend and assaulting her during a two-hour period on Aug. 27, 2013.
Defense attorney Rob German said this is not a normal move, “but you don’t lose anything by having him testify.”
German said Christianson would be on the stand to dispute the accusation that he attempted to strangle Journey Kopka, as well as issues with the knife the 18-year-old Grand Haven woman testified he threatened to use on himself and on her.
His mother, Kerri Christianson, will also finish her turn on the stand today with cross-examination from Assistant Prosecuting Attorney Karen Miedema.
Kerri testified Wednesday that her son’s relationship with his former girlfriend was “toxic.”
“I felt like they were oil and water together,” she said. “They were too identical. They were too needy.”
Kerri said she was originally upset about the couple’s age difference. Her son was 18 and Kopka was 15 when they started seeing each other.
“It was not appropriate,” the mother said.
Kerri noted that her son became more stressed as the relationship continued with an on-again, off-again pattern.
