Billy Baldwin was shocked to learn he grew up with Rex Heuermann, the man accused of killing four women on Long Island and leaving their remains near Gilgo Beach.
“Woke up this morning to learn that the Gilgo Beach serial killer suspect was my high school classmate Rex Heuermann,” the actor, 60, tweeted on Friday.
Baldwin then shared that he and Heuermann, 59, were both part of the class of 1981 at Berner High School in Massapequa, NY.
“Married, two kids, architect,” the “Flatliners” star added. “‘Average guy… quiet, family man.’ Mind-boggling… Massapequa is in shock.”
He concluded, “23andMe strikes again???”
Baldwin explained in the comments section of his Instagram post about the revelation that the reference to 23andMe, a DNA testing kit, was pure speculation about whether that is how police were able to track down Heuermann.
“When people allow their 23 and me DNA results to be posted publicly it can often resolve a cold case crime or paternity issue because they can link someones child or niece or nephew to a suspect by their 23 and me results,” the “Northern Rescue” star told one of his followers.
Baldwin’s fans expressed their dismay over the fact that the celeb was in such close proximity with an alleged serial killer at one time.
“Damn! That’s so scary when killers turn out to be the guy next door,” one person commented.
“That’s so wild Billy! Did you get serial killer vibes back then?” another follower asked. “One of the besties from high school went on to commit a notorious crime. Obviously I didn’t see it coming but hindsight I totally see it happening.”
While Baldwin has not spoken out about Heuermann’s character, a source who knew the alleged killer told The Post Friday that he was “weird” and a “big talker.”
“He would always stand out. He was very personable. He would always make a point to talk to everyone in the room,” one person claimed.
“He was a big talker, promising to make professional connections and then never following through.”
However, they added of the New York City architect, “He was weird. He was always odd. He’d mosey around. We knew something was odd about him.”
Heuermann was taken into police custody Thursday after his DNA — which police found on a discarded pizza crust — matched the DNA found on the hair of one of the victims Megan Waterman.
His arrest is tied to the infamous “Gilgo Four,” the women who were found wrapped in burlap within days of each other in late 2010.
Heuermann has been charged with both first- and second-degree murder in the case of each of the victims. He pleaded not guilty.
