P. Zielinski

Prosecutors expect murder suspect Peter J. Zielinski to enter a not guilty plea after a psychological evaluation is conducted.

Zielinski, 39, is expected to appear Monday, Sept. 26 in front of Marion County Circuit Judge Dale Penn at the Marion County Courthouse in downtown Salem.

Doug Hanson, a Marion County deputy district attorney, said Zielinski will be evaluated by a psychologist in the meantime. He’s been indicted on one count of murder.

Hanson said he expects Zielinski to plead not guilty. Zielinski was arrested in January after his wife, Lisa Zielinski, was found shot to death in their north Keizer home on Jan. 12. She was 38 years old.

“That can change and there’s always negotiations that take place,” Hanson cautioned.

Noel Grefenson, one of Zielinski’s attorneys, declined comment.

Peter Zielinski remains in the Marion County Jail. A probable cause statement released by Marion County indicates he shot his wife in their home early Wednesday, Jan. 12, while their five-year-old child was asleep in another room. Police said he came to the Keizer Civic Center shortly after, calling 911 to inform dispatchers his wife needed an ambulance.
