9/11 25th anniversary live updates: Families gather for ceremonies at World Trade Center, Pentagon, Shanksville

Family members of 9/11 victims are continuing to read their names at the downtown Manhattan ceremony.

The granddaughter of FDNY Lt. Robert Wallace said, “Not many moments go by where I don’t think about you.”

“Papa, even though we never met, I see you in everything. In mom, in Nana … and your seven grandkids,” she said.

“We will never forget your heroic sacrifice,” she said.

Cantor Fitzgerald employee William Raub's daughter was just 6 years old on 9/11.

"I can still feel how much you love me 25 years later,” she said, “and I’m so lucky and so proud to be your daughter. We miss you so much."

The wife of Cantor Fitzgerald employee John Candela said, "Thank you, God, for putting John in my life and for the peace I have knowing that I will see John again in heaven."

“John, I love you tons. I miss your hugs. God bless us all and God bless America."

The names of all the victims can be seen here on the 9/11 Memorial & Museum website.

Hundreds of people gathered in Shanksville, Pennsylvania, to mark the 25th anniversary of United Flight 93's crash.

The family members of the 40 passengers and crew who were killed read their names, accompanied by bells.

The color guard folded a U.S. flag and placed it on a giant rock near the edge of a grove of hemlocks. That rock is where some of the very last pieces of Flight 93 came to rest.

Family members are continuing to read the names of 9/11 victims at the downtown Manhattan ceremony.

Patricia Smith, whose mother, NYPD officer Moira Smith was killed while responding to the World Trade Center, said her mom "died the way she lived -- surrounded by people she wanted to help, doing the job that she loved."

"Mom, we love you and we miss you every day. I’m so proud to be your daughter and I’m grateful for the example you set," she said. "… Thank you for your courage, thank you for setting the standard, and most of all, thank you for your sacrifice."

The reading of the names is ongoing at the 9/11 ceremony in lower Manhattan, recognizing all those who lost their lives.

“I hope I made you proud,” said the granddaughter of FDNY Capt. James Corrigan. "You are missed, remembered and loved, always.”

The daughter of victim Norberto Hernandez described him as a “gentle giant” who “loved like no other.”

She said she became an NYPD officer in her father’s memory. Overcome with emotion, she said, “it was an honor and a blessing to be raised by such a wonderful man.”

The daughter of police officer Ramon Suarez said, “Dad, we miss you we love you. I hope I’m making you proud. I’ve carried you with me throughout every accomplishment and every milestone.”

She said she’s getting married soon and wishes he was there to walk her down the aisle.

“I will always keep your love and memory forever,” she said.

The son of victim John Hart said, “You are gone, but loved and remembered every day by your friends, your family, your 10 incredible grandchildren. Though you’ve never had the opportunity to meet them, they will know you.”
