A Columbia man will serve at least seven-and-one-half years in prison for fatally stabbing his girlfriend’s husband earlier this year.

Ronald Lee Sheetz, 42, pleaded guilty Friday to voluntary manslaughter in the Jan. 15 death of Michael Oberdorff Sr., 44.

The sentence, with a maximum of 15 years, was part of a negotiated plea agreement approved by Oberdorff's family.

Sheetz, wearing blue jeans, a blue shirt and blazer and a long, braided ponytail, whispered “sorry” when Judge Donald Totaro asked if he had anything to say after making sure Sheetz understood his plea.

“I find that the circumstances that this crime presents are selfish and cold-blooded in the extreme,” Miller said of Allison Oberdorff.

The sentencing guidelines for the crime called for an approximate three-to-14 month sentence. However, Miller said, those guidelines don't properly capture Oberdorff's behavior.

“Sorry, Ms. Oberdorff,” she said. “This to me, short of murder itself, is almost as bad as it gets.”

....Oberdorff's daughter, Emily, read a prepared statement that called her a “murderer” and an “addict” that manipulates people, drove a wedge into the family and only cares about getting high.
