MASON, Ohio (WXIX) - Prosecutors are still trying to piece together the motive behind a Mason workplace shooting that left one man dead on July 22.

David Cohen is accused of killing 29-year-old Vincent Stoetzel after he allegedly shot him 22 times at Carter Lumber, court documents say.

Investigators recovered 25 shell casings at the scene that day, according to Mason Police Detective Andrew Simmons.

During a bond hearing Monday, Warren County Prosecutor David Fornshell said Cohen worked at Carter Lumber for about a week before he quit, just days before the shooting.

Fornshell did not say why Cohen quit, but said it was for “innocuous” reasons.

“There wasn’t concern on the part of the employer that anything like this was going to happen,” the prosecutor said. “It wasn’t that type of resignation from the position that he held.”

Prosecutors also said the victim and suspect had known each other socially outside of work for about three weeks.

Although a motive is not clear, prosecutors do believe Stoetzel was the intended target of the shooting.

“When you hear of an incident of workplace violence ... people think ‘Well, that must have been the person who was their supervisor or who fired them,’ or something along those lines,” Fornshell explained. “And thus far, there’s no evidence that that’s what occurred here.”

Cohen continues to plead not guilty to the aggravated murder charge in Mason Municipal Court.

A Mason Municipal Court judge granted prosecutors’ motion to hold him in jail without bond.
