A fatal shooting Wednesday morning that took the life of New Jersey council member Russell Heller was not found to be politically motivated, according to authorities. 

"Investigators with the Somerset County Prosecutor’s Office along with Franklin Township Police continue to investigate the circumstances that led to the homicide shooting of Mr. Russell Heller yesterday in Franklin Township," Somerset County Prosecutor's Office Deputy Chief Frank Roman Jr. told Fox News Digital in an emailed statement. 

"Investigators have confirmed that Mr. Heller was a Republican Councilman for Milford Borough (Hunterdon County)," Roman said. "The investigation has revealed that the shooting of Mr. Heller was not politically connected with his elected office or political affiliation."

Somerset County Prosecutor John P. McDonald had previously announced that Heller, 51, had been killed in his car at the Franklin Township PSE&G facility, where he worked, shortly after 7 a.m. ET. Police responded to multiple 911 calls reporting a shooting victim at the Somerset parking lot on Weston Canal Road. Heller was dead when officers arrived the scene.

Both Heller and Dwumfour were Republicans, according to reports.

While Heller was the intended target, authorities are still trying to determine a motive for the shooting. Police have said it was an isolated incident.
