Bergen County Prosecutor John Molinelli says 17-year-old Travis Gallo stabbed sister Teia Gallo multiple times around 5:30 p.m. Thursday in their Washington Township home.
The prosecutor says the boy would appear in court Friday morning.
Officials say the suspect and victim are among 12 children in the family. The prosecutor says one of their other siblings was home at the time of the stabbing and called 911.
