Kayli Fagundes: Family mourns death of Port St. Lucie teen killed in I-95 crash

PORT ST. LUCIE, Fla. - John Fagundes can't make sense of it. "I'm at a loss for words.  I'm suffering immensely right now."

His daughter Kayli was killed in a crash on I-95 Wednesday in Port St. Lucie. "It's just been me and her.  She's my sidekick."

"She was ready to conquer the world,” said her uncle Mark Campbell.

He watched as Kayli, his daughter Tyme and John's stepdaughter Arianna bonded like sisters as they grew up together.

He called them the "Powerpuff Girls" after the 90s cartoon. "The hair, the temperaments, the personalities… fit them to a tee."

Shy by nature, those who knew Kayli say she was poised to break through.  The 17-year-old was planning to reenroll in the state's online high school so she could graduate this year.

"She wanted to be famous.  Definitely.  She would tell me that,” said her cousin Tyme Campbell. 

The Florida Highway Patrol is looking for a gold or tan-colored car driven by a female that may have contributed to the crash.

"I hope somebody will come forward and tell us what they seen.  Whether they heard anything,” Kayli’s father said.  "I just miss her so much.  I wish she was here.  This is a nightmare.  Beyond a nightmare."

Kayli’s family is hoping someone can help them get answers.
