Nearly 40 years after a Brighton wife and mother was murdered, prosecutors believe they've caught her killer.

Prosecutors say James "Jim" Krauseneck killed his wife, Cathleen Krauseneck, inside their Brighton home on Feb. 19, 1982. She was 29 years old.

Krauseneck appeared in court Friday morning where he pleaded not guilty to an indictment charging him with murder.

At the time of the murder, Krauseneck told police he found his wife dead with an ax in her head inside their home. Their daughter, who was 3-and-half years old at the time, was also at home that day.

Karuseneck's defense attorneys released a statement on Friday.

"Jim’s innocence was clear 37 years ago; it’s clear today," the statement read. "At the end of the case, I have no doubt Jim will be vindicated. We believe bringing this indictment is a mistake. I have no doubt that we’ll demonstrate this as we defend Jim against this misguided prosecution."

The case became known over the years as the Brighton ax murder.
