BROOKLYN - Investigators have released video of a woman they want to talk to about the murder of a well-known business owner in East Flatbush. 

According to police, Sergio Bosse was found dead inside his Albany Avenue apartment last Friday after being stabbed in the back of the head. It was initially believed that the 69-year-old was shot. 

They say the woman was an associate of Bosse, and they want to ask her some questions. 

Bosse leaves behind a daughter and two grandchildren, and had lived alone since the passing of his wife several years ago.
