No bail for Brooklyn woman who stabbed father to death, wounded sister

The Brooklyn woman who stabbed her dad to death, left her sister fighting for her life and told cops she “wanted them dead” was held without bail, officials said Wednesday.

Nikki Secondino, 22, remained in custody following an arraignment in Brooklyn Criminal Court on Tuesday.

Secondino initially told cops a pair of home invaders had broken into the family’s apartment above a plumbing shop on 17th Ave. near 82nd St. in Bensonhurst last Thursday, cops said.

Later, she admitted to cops she had stabbed her father, Carlo Secondino, 61, and her younger sister Liana Secondino, 19.

The medical examiner deemed Carlo’s death a homicide Wednesday, noting he was killed due to “blunt impact injuries of head and sharp force injuries” after he was stabbed repeatedly.

Police were called about 5:50 a.m. to the apartment, where they found Liana standing outside with multiple stab wounds, according to a criminal complaint.

“My sister stabbed me,” prosecutors said Liana told cops. “Have you seen my dad? You have to get him.”

Cops entered the apartment, where they found Carlo dead and laid out on the kitchen floor in a pool of blood after he was repeatedly stabbed.

Nikki was taken into custody and charged with murder, attempted murder and criminal possession of a weapon.

As she admitted to the brutal slaying, she told cops she first “bashed his head in with a hammer” as her father slept on the couch before she grabbed a knife, authorities said.

“I grabbed my favorite German steel knife and stabbed the s—t out of him,” she told cops. “My sister came out of her bedroom and tried to stop me and then I stabbed her in the back, head and stomach.

“I wanted them dead,” she added. “If I saw the 911 caller, she would be next.”

Neighbors told the Daily News that tense domestic conflict was nothing new for the family, though it was not clear what led to the bloodshed.
