A Warren County judge found David A. Cohen incompetent to stand trial Thursday, Oct. 15, and ordered him committed to a mental health facility for treatment aimed at restoring his competency. Cohen, 34, is accused of fatally shooting a former coworker at Carter Lumber in Mason on July 22.

Judge Timothy Tepe issued the order after a competency hearing Thursday, Oct. 15, in Warren County Common Pleas Court, the Dayton Daily News reported. Cohen faces charges of aggravated murder, murder and having weapons while under disability. He will remain at the facility for treatment aimed at restoring his competency to stand trial.

Prosecutors allege Cohen shot and killed Vincent "Vinny" Stoetzel, 29, a father of four, just after 1 p.m. July 22 at Carter Lumber on Reading Road in Mason. Mason police detective Andrew Simmons testified at a July hearing that approximately 25 shell casings were recovered at the scene.

Warren County Prosecutor David Fornshell said it was not clear how many times Stoetzel was shot. A precise number may never be determined because of potentially intersecting rounds, he said.

The arrest happened fast.

Employees at Carter Lumber identified Cohen as the suspected shooter because he had briefly worked there, Fornshell said. That quick identification allowed investigators to track Cohen's vehicle through Flock cameras, automated license plate readers that capture vehicle details and store them for law enforcement use.

Springdale police stopped Cohen on I-275 within 30 minutes of the shooting, Fornshell said. Body-camera video captured an officer ordering Cohen to drop a gun from the vehicle, WLWT reported. Simmons testified the pistol recovered was the same weapon used in the killing.

Cohen had resigned from Carter Lumber after about one week on the job, the week before the shooting. He quit for what Fornshell called a "fairly innocuous reason" that did not involve any disagreements. Stoetzel had helped Cohen get the job, Fornshell said.

The two men had known each other socially for about three or four weeks through an arm wrestling club Stoetzel started. Fornshell said there was no dispute between them and no one viewed Cohen as a disgruntled employee.

"I will say that I 100% believe he was targeting Vinny," Fornshell said.

Cohen was prohibited from possessing a firearm due to a prior crime of violence. In 2012, he was sentenced in Hamilton County Common Pleas Court to a year in prison for assaulting a police officer, according to court records.

The Hamilton County Sheriff's Office officially ended its Flock camera program Oct. 2 after Sheriff Charmaine McGuffey suspended the county's 75 cameras Sept. 3, WCPO reported. The sheriff’s office said internal audits found no misuse of its system but said it would only use tools meeting its standards for privacy, transparency and local control over sensitive information.

The Dayton Daily News report did not identify a date for a follow-up competency hearing.
