ST. CLOUD, Minn. (AP) -Opening statements in the trial of a man accused of killing a Mendota Heights police officer have been delayed until Thursday, after prosecutors said they have new evidence.

Opening statements in the trial of Brian Fitch Sr. were scheduled to begin Tuesday morning in Stearns County. The trial’s start was initially delayed by a few hours when a female juror was released after expressing safety concerns, and a replacement was picked.

But the Star Tribune reports the trial was ultimately pushed to Thursday after prosecutors said they had new evidence that Fitch told another jail inmate that he killed Officer Scott Patrick during a July traffic stop in West St. Paul.

A judge is allowing the evidence, and delaying the trial so both sides can investigate the alleged confession.
