HOUSTON -

America is remembering a day that changed our nation forever.

It was 12 years ago when our country was hit with terror attacks in New York, Washington and Pennsylvania.

Houston is forever linked to the September 11 terror attack. The local parents of one victim built a memorial garden so they and we never forget.

Lauren Catuzzi-Grandcolas grew up in Houston and went to Stratford High School.

She was married, three months pregnant and a passenger on Flight 93 on September 11, 2001.

Visitors to the memorial garden in downtown stopped by to reflect and remember the people who, like Lauren, were killed.

Mayor Annise Parker led city council members in a moment of silence Wednesday morning at City Hall.

Many still remember where they were on that day, when airplanes crashed into the twin towers, the Pentagon and a field in Pennsylvania.

Flags were lowered to half-staff throughout Houston and the country out of respect for the nearly 2,978 innocent men, women and children who were killed on September 11.

On Wednesday the Atascocita High School National Honor Society placed flags around a flag pole honoring every American citizen who lost their life in 2001.

Monique Zibi organized the ceremony. She lost her 26-year-old cousin in the second tower.

"He called his family and said we're going to be OK. They just want us to evacuate. He didn't have any idea of what happened. they continued walking down and from that moment we never heard from him again," said Zibi.
