ENGLEWOOD, N.J. (CBSNewYork) — Police on Saturday were questioning a New Jersey man several hours after his elderly parents were found stabbed to death inside their Bergen County home.

Investigators say one of the couple’s two sons asked police to conduct a welfare check at his parents’ home in Englewood shortly before 11 a.m. After entering the home on Lafayette Place, the officers discovered Edward Boduch, 71, and his wife Miroslawa Potoka, 72, deceased from multiple stab wounds.

Police found the couple’s car parked at a nearby Shop Rite, where they took their other son into custody around 5 p.m.
