BROOKLYN - A well-known business owner was found bound and shot to death inside his East Flatbush apartment on Friday. 

According to police, 69-year-old Sergio Bosse was found at 497 Albany Ave. just after midnight with a gunshot wound to the back of his head. He was pronounced dead at the scene. 

Neighbors say he owned Sergio's Grocery, and describe him as a very friendly and quiet man who was always trying to help others. 

Those who knew Bosse say he leaves behind a daughter and two grandchildren. His wife passed away several years ago and he has since lived alone. 

The investigation is ongoing, and so far no arrests have been made.
