Baby-faced teen shot dead in NYC love triangle murder-suicide revealed in first pics

The tragic teen allegedly shot dead by his girlfriend’s jealous ex was a baby-faced 17-year-old — as the first images of the youngster were revealed Sunday.

Neo Secaira left work early on Saturday to pick up his 19-year-old girlfriend in Bayside on Saturday night, only to walk into a bloody murder-suicide that left him and US Marine Frank Liu, 28, dead while their mutual love interest looked on in horror, police and sources told The Post.

Photos posted on Secaira’s social media accounts show a smiling youngster with a crop of curly hair, while another pic shows the smiling teen leaning up against a Big Apple storefront.

“At 7:50 this morning, a woman rings my bell,” the slain teen’s distraught mom, Yolanda Secaira, said Sunday. “She asked me, she said, ‘Your son has curly hair?’ I said, ‘Yes.’ She said my son killed your son. I said, ‘What? Your son killed my son?’ She said yes.”

Liu’s father said his son, a Marine who was about to be redeployed overseas, was distraught over losing military pals in the Middle East — compounded by his young gal pal’s recent change of heart.

“I say, why? It’s just one girl. There are many girls,” Huili Liu said Sunday. “The girl lived in my apartment for half a year. He spent quite a while with her. She decided to study here.”

Cops called to the home around 10 p.m. Saturday said they found Secaira with gunshot wounds to the chest and Liu with an apparent self-inflicted gunshot wound to the head.

Both were rushed to New York Presbyterian Hospital, where they were pronounced dead.

Their mutual love interest, who has not been identified, witnessed the carnage, sources said.
