WASHINGTON TOWNSHIP - A Washington Township teen is charged with stabbing his sister to death following an argument yesterday.

The Bergen County Prosecutor says Travis Gallo,17, stabbed his sister, 20-year-old Teia Gallo, multiple times with a kitchen knife in their home at around 5:30 p.m. yesterday.

Tax records show the home is owned by Theresa and Robert Gallo. He is a well-known Hackensack gynecologist.

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.
