GERMANTOWN The Germantown apartment building where a retired Villanova University professor was found stabbed to death Monday night was not easily accessible to outsiders, one of the building’s owners said Wednesday, suggesting that the woman might have known her killer.
Carol W. Ambruster, 69, a retired professor of astronomy, was found by her roommate in the kitchen of her apartment in the 5500 block of Wayne Avenue with a knife in her neck about 9 p.m., police said. She also had been stabbed in the chest.
Ambruster, a tenured professor in the department of astronomy and astrophysics at Villanova, retired in 2011, a university spokesman said. Her former colleagues said she was the author of about 80 published papers on astronomy.
