Cameras will be banned from the upcoming trial of a Lawrence carpenter charged with strangling his wife.

Judge Paula Martin said Thursday she worried about the effects a televised trial could have on Martin K. Miller’s junior-high-age children, who are expected to be key witnesses. Still cameras from newspapers will also be banned.

Miller is set to stand trial June 13. He’s charged with killing his wife, Mary E. Miller, in July 2004 inside their home at 21st and Carolina streets.

Prosecutors said during Thursday’s hourlong, pre-trial hearing that they would try to show jurors Miller was living a “double life.”

Assistant Dist. Atty. Brandon Jones said he intended to put on pornographic photos and detailed evidence of a sexual affair Miller was having at the time of his wife’s death.

Defense attorney Mark Manna is asking that prosecutors not go into too much detail about his client’s sexual tastes. Showing jurors the hundreds of pornographic pictures found on Miller’s computer, he said, is unnecessary.

“At some point, it can become too prejudicial,” he said.

Jones said he didn’t plan to put on hundreds of photos, but he said some of the evidence was relevant at trial because it showed that Miller — a former Christian-school trustee — wanted to pursue an “alternative lifestyle” that wasn’t possible with his wife.

“It’s such a stark contrast to the life that he tried to espouse to the public,” Jones said.

Martin said many of the decisions about graphic evidence couldn’t be decided beforehand. She said Manna should object at trial if he thinks the state is going into too much detail.

She set deadlines for prosecutors to show Manna what they plan to introduce.

Prosecutors have alleged Miller killed his wife, in part, because he thought divorce was unacceptable for religious reasons.
