Alleged Lake George killer dad Luciano Frattolin once admitted he had to learn to live with his slain daughter’s “messy art projects’’ and “chaotic’’ toys because of his obsession with keeping “perfect order.’’

On Frattolin’s bio page for his Montreal-based coffee company Gambella Coffee, he alludes to painful hardships he has had to endure, including “incidences of racism,” “feelings of isolation” and the death of his father as a teenager.

He mentions an “unfortunate event” in 2019 that he says “severely affected his well-being” and necessitated a “long and arduous” road to recovery, too. He did not see elaborate on what happened, although cops said his relationship with his former wife apparently badly soured around that time.

Frattolin, 45, also speaks glowingly of the “light of his life,” his daughter, Melina, 9 — whom he now stands accused of murdering — and admits to some “rigid tendencies” she helped him overcome.

“Melina has taught Luciano to let go of his rigid tendencies to keep everything in ‘perfect order’ — his love for Melina’s messy art projects and chaotic ensemble of toys supersedes his love for a meticulously spotless home,” the self-professed neat-freak dad wrote.

Still, despite his obstacles, “He was left reinvigorated and reconciled the difficulties he faced during his youth by embodying the Nietzschean attitude of, ‘That which does not kill him makes him stronger,’ ” says the bio, which has since been taken offline.

“He readily admits the mistakes of his past life and uses such reminiscences as momentum for doing better.”

Frattolin’s Instagram page, where his bio includes the descriptor “loving father,” is loaded with photos of him and Melina smiling and looking happy together.

The “very reserved” dad spent his time between Canada and Italy, an acquaintance told the Press of Montreal.

Frattolin’s company had recently been filming a promotional documentary, and a worker at the studio commissioned for the project told the outlet, “There was nothing unusual about him, and he adored his daughter.

“She was so charming,” the employee recalled of Melina.

Police say Frattolin called in a bogus kidnapping report hours before her body was recovered in shallow water in Ticonderoga, New York, on Sunday while they were on vacation in the Lake George area some 30 miles away.

Investigators later said there were no indications she had been abducted and that her father’s story contained inconsistencies, WRGB reported.

Frattolin, who was born in Ethiopia, was booked into Essex County Jail at 2:04 a.m. Monday and charged with Melina’s murder.

Video taken outside the jail shows him clad head to toe in a white jumpsuit and shackled at the wrists and ankles before being led by a pair of New York state troopers into a police SUV.
