The Duluth man accused of fatally stabbing his wife last month will contest a murder charge, his attorney indicated Monday.

Ryan Richard Jazdzewski, 40, appeared in State District Court on a count of intentional second-degree murder in the June 2 slaying of 41-year-old Nicole Ann Jazdzewski at the couple's Chester Park residence.

Defense attorney Paul Shaffer told a judge he intends to challenge the admissibility of statements his client made to police and medical personnel, as well as the sufficiency of probable cause to support the charge.

Sixth Judicial District Judge Theresa Neo scheduled an Aug. 29 hearing for testimony on those issues.

Authorities said Jazdzewski told police he "lost it" and "just started stabbing" his wife during an argument that came hours after she told him she wanted a divorce.

Police responded to the couple's home, 818 Chester Park Drive, after it was reported that their 7-year-old daughter was covered in blood and asking for help.

Officers said they entered the residence and found Nicole Jazdzewski lying on her back in the kitchen. She appeared to have suffered multiple stab wounds to the torso, and there was a "large amount of blood" throughout the kitchen, according to a criminal complaint.

In a hospital interview, Ryan Jazdzewski allegedly detailed the incident to investigators, stating, "I killed her." He said he had spent most of the day drinking beer, doing artwork and playing with their kids while ignoring Nicole after she told him she wanted a divorce.

The defendant told police that he was preparing to go to bed when they got into a verbal argument, according to the complaint. The incident "escalated," he reported, and Nicole grabbed a kitchen knife for self-defense.

Ryan Jazdzewski allegedly stated he didn't believe his wife was going to use the knife, but he took it from her to prevent her from calling 911. He acknowledged stabbing his wife approximately 10 or 12 times, stopping only when the 7-year-old told him, "Don't kill mom," according to the complaint.

Police said Ryan Jazdzewski also called his own mother and admitted to the incident before police arrived on scene.

Shaffer indicated in a court filing last week that he would argue self-defense and intoxication if the case proceeds to a jury trial. Under Minnesota law, voluntary intoxication may be taken into consideration "when a particular intent or other state of mind is a necessary element to constitute a particular crime," such as intentional second-degree murder.

Neo on Monday also denied a defense motion to either reduce Jazdzewski's bail or grant him a referral to intensive pretrial release. He remains in the St. Louis County Jail on $750,000 bail.
