A Lawrence man convicted of murdering his wife in 2004 was back in a Douglas County courtroom Monday.

Martin Miller, 50, is claiming his constitutional rights were violated during the first degree murder trial in June 2005.

He is currently serving 25 years to life in prison for strangling his wife, Mary, inside their central Lawrence home.

Miller is arguing that he received “ineffective assistance” from his attorney, Mark Manna, during the trial.

Manna spent Monday afternoon on the witness stand, testifying about how he determined which potential jurors to strike.

Miller is expected to take the stand today when the hearing continues.

District Attorney Charles Branson said he doesn’t believe there were any trial errors that would affect Miller’s constitutional rights and that the conviction should stand.

The Kansas Supreme Court upheld Miller’s conviction in 2007.
