Alexandra Van Rensselaer Devereux Gross, 68, was murdered at her home in Villanova, Pennsylvania, on July 16, 1982. She, her husband Courtlandt Gross, and their housekeeper Catherine VanderVeur were found shot to death, a crime that shocked the Philadelphia Main Line community.

Authorities arrested 23-year-old drifter Roger Peter Buehl after tying him to the scene with circumstantial evidence. Investigators cited a red Buick seen near the Gross estate the day of the killings and forensic links between bullets used in the murders and an armed robbery connected to Buehl. In January 1983 Buehl was tried and convicted of first-degree murder in all three deaths and received death sentences for each count.

The three deaths left a lasting impact on the family and neighborhood. Did anyone in the area at the time notice a red Buick or other unusual activity around the Gross property on July 16, 1982?
