Mark Jensen Kenosha murder trial: Defense rests, Jensen will not testify

The defense rested its case on Monday, Jan. 30 in the retrial of a man previously convicted of killing his wife more than two decades ago.

Mark Jensen, now 63, was convicted in 2008 of killing his wife Julie Jensen in their Pleasant Prairie home in 1998. Prosecutors say Jensen poisoned his wife with antifreeze, drugged her and smothered her. Jensen maintains his wife killed herself. He was having an affair with a woman in the months prior to her death and she moved to Kenosha in the months afterward.

"Had you ever seen him that way before?" asked the defense attorney.

"That was the first time I’d seen him cry," said David Jensen, Mark Jensen's oldest son.

David Jensen testified that he and his dad made a homemade fishing pole as a Christmas gift for his mom.

"It was my dad, my brother, Douglas, and I," David Jensen said.

"He came out crying not terribly long after," David Jensen testified.

The then-8-year-old boy remembers his mom was not getting out of bed and ill – as far as he knew. He asked his dad, Mark, about her.

"We were going to come straight home from school and check on her," David Jensen said.

"Yes," David replied.
