DAVENPORT, Iowa (AP) — A prosecutor told jurors on the opening day of a murder trial that they were going on a journey in time to learn about an Iowa high school girl who was slain more than 40 years ago.

Testimony began Wednesday in the trial of Jerry Burns.

He’s accused of fatally stabbing 18-year-old Michelle Martinko at a Cedar Rapids mall.

A prosecutor says Martinko’s lungs and aorta were pierced and she lost about a third of her blood.

The prosecutor also says DNA shows that Burns’ blood was found at the crime scene.

But defense attorney Leon Spies told jurors that evidence will show Burns isn’t guilty of first-degree murder.
