Story summary

On Oct 2, David Grodnick, 61, an insurance executive from Princeton, New Jersey, fatally shot his wife Lora and their daughter Sloane, 24, before taking his own life inside their $1.75 million mansion in Montgomery Township. Police responded to a welfare check request on the day before the discovery but couldn’t locate anyone; they gained entry the next evening to find all three deceased from gunshot wounds. Neighbors noted that the Grodnicks’ once meticulous lawn maintenance had ceased weeks prior, which one neighbor saw as an unusual sign of trouble ahead. The Somerset County Prosecutor’s Office confirmed these deaths were a tragic isolated incident with no broader public threat.
