The New York City architect arrested in connection with the infamous “Gilgo Four” killings boasted about his career in an interview over a decade after the alleged murders, a video clip shows.

In a video posted by Bonjour Realty last year, Rex Heuermann detailed his work history with his eponymous architecture firm, where he served clients including American Airlines and Catholic Charities.

“I’ve been working in Manhattan since 1987,” Heuermann, 59, told the interviewer.

The clip was posted on Feb. 17, 2022, more than 11 years after the bodies of four women were found wrapped in burlap along Ocean Parkway near Gilgo Beach in December 2010.

The so-called “Gilgo Four” – Melissa Barthelemy, Amber Lynn Costello, Maureen Brainard-Barnes, and Megan Waterman – had all been strangled, and are believed to have been murdered between 2007 and 2010. 

Heuermann was arrested at his Massapequa Park home in connection with the killings early Friday, multiple sources told The Post.
