NORTHAMPTON TWP., Pa. (WPVI) -- Authorities say a man and a woman were found dead in an apparent murder-suicide in Holland, Bucks County.



It was a son-in-law who made the horrible discovery around 3:50 Saturday afternoon inside a home in the unit block of Lempa Road.



His wife sent him over after she hadn't heard from her parents.



"It's a little bit unbelievable and we're still trying to deal with it," said Amy Rifkind, neighbor.



Stunned neighbors identified them as Boris Sereda and his wife Enna. They say Boris had been suffering from a long term illness.



Investigators searched the couple's split level home for clues but it appears the 65-year-old husband shot and killed his 61-year-old wife before turning the gun on himself.



"He had been battling, I believe cancer, for a few years and I heard he took a turn for the worst recently and maybe he was depressed, we're not sure," said Rifkind.



"They were really nice. I didn't get a chance to really talk to them much but they would always wave to us and they just seemed really friendly," said Liz Rifkind.



Action News has learned that Boris was the longtime owner of Sereda Enterprises, a fine jewelry maker on South 7th Street in Center City.



He was in business on Jeweler's Row for more than three decades.



"Family business, good guy, no complaints, no issues, never a problem," said Faust Capobianco, neighbor.



Neighbors say they would often see Enna walking with their grandchildren.



Bucks County detectives and police brought out boxes of evidence from the couple's home on Sunday.



Capobianco, who just spoke with Boris on Saturday, says he's trying to wrap his head around the tragic incident.



"Like any other conversation, just a normal day. That was what caught everyone on this block off guard - just shocked," he said.



An exact cause of death has not yet been determined.



Officials are investigating.
