Drinking a beer and cracking jokes with colleagues, he seemed like any co-worker enjoying a night out after a busy day in a Manhattan office.
But once he left the bar and headed back to his Massapequa Park, Long Island home the architect Rex Heuermann allegedly went Jekyll and Hyde and prowled his neighborhood looking for his next victim to kill as his wife and children slept.
Katherine Shepherd worked with Heuermann in the same midtown Manhattan office at 525 Seventh Avenue in New York City's Fashion District during the early 2000s.
She was working for an architectural design firm and his company was providing city permits.
On occasion, she and her co-workers would gather at Pete's Tavern in Gramercy Park.
