Devastating reason mourners wore pink to services for LI teen slain by ex in botched murder-suicide

More than a thousand mourners packed a Long Island funeral home Sunday to remember Emily Finn — many wearing pink to honor the bubbly teen killed in a senseless botched murder-suicide.

On display inside the Raynor & D’Andrea Funeral Home in West Sayville were Emily’s pink ballet slippers, a poster of the smiling teen with her flute from the high school marching band and reminders of the 18-year-old’s many academic achievements before she was shot dead, allegedly by her ex-boyfriend.

Her devastated mom, Cliantha, wore a pink sweater — part of the family’s wish to display the girl’s favorite color, which saw dozens of pink ribbons, bandanas, boots, jackets and bows at the funeral home.

“She just had that special spark,” said Heather, a friend of the slain teen. “She was so full of life, and she loved her family and her brother and her grandparents so much.

“All she ever wanted was to do good for the world, and it all got taken away, just like that,” the grieving teen said. “I can’t stop crying.”

Emily’s ex, 18-year-old Austin Lynch, is now facing second-degree murder charges for allegedly shooting her dead inside his Nesconset home Wednesday during her Thanksgiving break from college — then shooting himself in the face, according to police.

The accused killer survived the self-inflicted blast.

The dead girl, a recent Sayville High School graduate, was a talented ballet dancer who trained at the American Ballet Studio in Bayport — even landing the lead role in a production of “Nutcracker” last year.

The young beauty was studying to be a teacher at SUNY Oneonta when she was killed.

She was to be cremated, with her ashes displayed in a pink box inside the funeral home alongside a bouquet of pink flowers, baby pictures and more recent photographs.

Along with her mom, Emily’s father, Ryan, and her brother, Kyle, hugged weeping mourners.

“Emily was the best, just the best,” another friend, who only identified herself as Hailey, told The Post. “She was an amazing dancer and an amazing friend, and such a family person.

“Being around all these people who love her so much, I keep imagining her being among them, living and smiling,” she added. “I’m just completely crushed. I’m devastated.”

Lynch, who had recently joined the Marines, will be arraigned on the murder charge as soon as he has recovered enough from his wounds, the Suffolk County District Attorney’s Office said.
