A wannabe New York Instagram influencer killed her father and critically wounded her younger sister in “an argument over a laptop,” prosecutors say.

Nikki Secondino, 22, was arraigned Monday on a murder indictment for the death of her 61-year-old father, Carlo Secondino, on December 28, the New York Post said.

After killing her father, Secondino stabbed her 19-year-old sister Liana, as CrimeOnline previously reported.

“My father was sitting on the couch. I hit him on the head with a hammer. Then I reached for my favorite German knife and stabbed the s*** out of him,” Secondino allegedly told investigators “My sister came out and tried to stop me, and I stabbed her in the back, head and stomach. I wanted them dead.”

The six-count indictment was unsealed in court on Monday, the Post said.

“This defendant is charged with brutally killing her own father and then stabbing her younger sister, allegedly following an argument over a laptop,” Brooklyn District Attorney Eric Gonzalez said in a statement. “My office will vigorously prosecutor this horrific case and seek justice for the victims.”

Secondino initially ran to a neighbor’s apartment for help, claiming that two men had broken into the family’s Brooklyn apartment. She eventually broke down and told investigators what really happened — after Liana Secondino survived the stabbing and told detectives, “My sister stabbed me,” according to the complaint. “Have you seen my dad?”

Nikki Secondino is due back in court on April 5, News 12 The Bronx reported.
