Police Question Person of Interest in Flatbush Avenue Murder

Following a homicide in a Flatbush Avenue business earlier this week, a man believed to be “John Doe Duffel Bag” is being questioned by police in the slayings of three Brooklyn shopkeepers. ABC reports that the police picked up a man who matches the man’s description in Bay Ridge this afternoon, though the Daily News says the man voluntarily walked into the 68th Precinct.

NBC adds:

The latest development comes as authorities are searching for a possible serial killer who has gunned down three Brooklyn business owners since the summer. Detectives who specialize in hate crimes and FBI analysts who specialize in behavioral analysis have joined the case, authorities said.
