John Kolonich, 46, was found in his car along Franklinville-Williamstown Road in Franklinville, dead with a gunshot wound to his head around 10:30 a.m. last Thursday, the Gloucester County Prosecutor's Office said in a statement.
Moments later, police were told that Kolonich’s wife, Melissa, 42, a local realtor, was dead from stab wounds inside their nearby home on Florawood Court in Franklin, authorities said.
The physician is believed to have stabbed Mellisa dead in their home before he left in his car and killed himself while heading southbound, the prosecutor's office said.
His vehicle left the roadway and went into the backyard of a Sandra Way home, authorities said.
The couple apparently shared one daughter together, according to Facebook. More than $7,000 had been raised on a GoFundMe for the girl's new legal guardian.
Kolonich founded his practice in 2004 and supported law enforcement and veterans, the Courier Post Online reports.
The physician's patients took to Facebook to mourn his loss.
"I feel for all of you," one person commented. "My heart broke when I heard the news today. It just doesn’t seem real. I will keep you all in my prayers."
Condolences poured in for Melissa as well.
