Family members tell The Record that Teia Gallo's funeral will be held at St. John the Baptist Roman Catholic Church in Hillsdale.
The Bergen County Prosecutor's Office says 17-year-old Travis Gallo stabbed his 20-year-old sister Teia multiple times with a kitchen knife after they got into an argument.
A younger sister was injured but not stabbed. It's not clear how serious her injuries are.
Teia Gallo was pronounced dead at Hackensack University Medical Center.
Travis Gallo appeared Friday at a closed hearing in juvenile court in Hackensack and had a not guilty plea entered by a public defender.
The Bergen County Prosecutor's office will decide within the next month whether to have him tried as an adult.
The brief court hearing was the first time Gallo had seen his son since the stabbing occurred, the newspaper reported, and Gallo said Travis seemed almost strangely composed.
"It's the scariest thing, to see your child led into a courtroom in shackles," Gallo told the newspaper. "I'm not sure that he understands the gravity of what he's involved in, but he seems to be pretty secure in his ability to stand up and speak to the judge."
The family has nine biological and three adopted children. The two apparently involved in the stabbing were both adopted.
