A state judge on Monday delayed one of the trials for Ian Howard, who is accused of killing a Lafayette police officer and shooting three other people, after prosecutors acknowledged they were late with a court filing.

Howard is accused of shooting and injuring Lafayette Officer Logan Signater, Craig Leopaul and Ameen Alfata in a Moss Street convenience store.

The 29-year-old, dressed in blue jeans and a bullet proof vest during his court appearance Monday, also is facing a first-degree murder charge, accused of killing police Cpl. Michael Middlebrook. The shooting occurred Oct. 1, 2017 at the Big Boy Discount Zone in north Lafayette. A trial date has not been set in that capital case.

Howard is facing three attempted first-degree murder charges and was supposed to begin trial on Nov. 18 for charges in the shootings of the three other victims.

But prosecutors were given an ultimatum by 15th Judicial District Court Judge Jules Edwards III after he learned Monday the state formally replied nearly two weeks after the dealine to a request from Howard's defense lawyers.

Edwards told prosecutors that either all video and statements from Howard would be inadmissible at trial or the trial could be delayed.

The state, represented by Assistant District Attorney Daniel Landry, Executive Assistant District Attorney Alan Haney and District Attorney Kenneth Hebert, opted for a later trial.

The new trial date scheduled is Jan. 21.

Haney argued he told Elliot Brown, who is defending Howard, the state would use all of the video and statements. He said that was necessary until prosecutors know whether Howard will enter an amended plea of not guilty by reason of insanity. He has until Oct. 31 to enter that plea.

Edwards told prosecutors they needed to file a formal written response so the court would know what was happening.

Haney also argued the defense has had the evidence for more than a year and should have had time to file any requests to suppress pieces of the video or statements.

While before Edwards on Monday, Howard's defense team also made other requests. The defense will inspect Howard's car this week. It also has set dates for an expert to sit down with Howard to help determine whether the defense wants to enter an insanity plea.

Edwards allowed the defense to access mental health records and notes about Howard without them having to become part of the court record unless an expert will speak on them.

Stephen Singer, who represents Howard, made multiple requests that hinge on whether the jury must reach a unanimous verdict. He argued Edwards should adhere to a lower court ruling that contends a jury must be unanimous.

As part of that argument, Singer said Howard's trial should be postponed until the U.S. Supreme Court rules on a case that will decide whether a jury must come to a unanimous verdict, which Howard's lawyers argue could affect his case. The high court is expected to take up the case after it reconvenes this fall.
