A courtroom has rarely seen a man confess to murder so calmly.

Convicted killer Steven Sandison, already serving life in prison for a 1991 murder, faces another life term after pleading guilty Monday to second degree murder in the 2013 death of his cellmate at Saginaw Correctional Facility in Saginaw, Mich.

Speaking before a judge, Sandison showed no remorse whatsoever.

“The reason I killed him was because he was a child molester,” Sandison told the court.

“If it’s all right, I can tell you where it started,” he said. “That night he was trying to justify why he did it, and I told him to keep quiet and that he’d have to leave in the morning, find a new cell. But he continued to talk about it, try to justify it.

“So, he was a little bit bigger than me, so I got down, and I hit him in his face a few times. When he fell, I wrapped a cord around his neck and I took his life.”

Sandison’s victim, 66-year-old Theodore Charles Dyer, was serving a 25- to 50-year sentence for sexually molesting a 9-year-old girl whose family he had befriended.

Sentenced in January, 2014, he would have been 91 before he was eligible for parole.

That’s not an issue anymore.
