“Hi, my name is Brian,” said Kayden’s stepfather. “I’m Kayden’s dad. I may have not been her biological father, but I was her dad. She was my little girl.”

More than 100 people gathered for a candlelight vigil at Edgewood Elementary School in Morrisville.

“I was Kayden’s first grade teacher and I’ve had the privilege and the honor to work with her these past 180 days,” said Jocelyn Settsman.

Seven-year-old Kayden Mancuso was a rising second grader.

“I hope we can find some kind of justice for her,” said Kayden’s aunt, Heather Giglio.

They showed some of her moves and played video of Kayden singing and dancing to “Fight Song” by Rachel Platten.

“There’s a lot of people out here tonight who are sad for Kayden, but we also need to be happy that there was a little girl in this world that touched so many lives,” said family friend Matthew Moffett.

Kayden’s body was found Monday morning at the home of her father, 41-year-old Jeffrey Mancuso. He was found dead in a second-floor bedroom from an apparent suicide.

Philadelphia police say Kayden was killed amid a “contentious custody battle.”
