NEW YORK – The daughter of a New York Police Department sergeant killed in the 9/11 terrorist attacks has been sworn in as a member of the force.

Brittney Roy, of Massapequa Park on Long Island, was sworn in Thursday along with 473 other recruits during a ceremony held at the city’s police academy in Queens, reported Fox 5 New York.

Sgt. Timothy Roy was assigned to the NYPD’s surface transit enforcement division. Now his daughter, Officer Brittney Roy, is walking in his footsteps. Sgt. Roy was working in Brooklyn courts when the terrorists flew two planes into the World Trade Center on Sept. 11, 2001.

The Officer Down Memorial Page indicated that Sgt. Roy witnessed the first plane crash into the north tower. He called his wife on his cell phone to tell her he would not be home that evening due to the rescue operations he anticipated being involved in.

The 36-year-old Sgt. Roy rushed to Lower Manhattan to help. He was last seen near the South Tower before it collapsed. His body was found the following March.

Sgt. Roy served with the New York City Police Department for 16 years, and was survived by his wife and three children, one of them was Brittney. He was posthumously awarded the New York City Police Department’s Medal of Honor for his heroic actions.

Brittney Roy, now 22, was 7 when her father died. She says she always dreamed of becoming a police officer.

Congratulations Brittney. You’ve chosen a noble profession!
