LATEST: The family of one of the victims is seeking answers after their daughter is killed in a private plane.
"This is something that could've been simply avoided," said Kash Christopher.
Christopher is the father of Helena Lagos.
"I have a lot of questions, considering my daughter was on that aircraft," he said.
The NTSB is investigating whether the Piper PA24 was a model that could have safely carried six people. Right now, investigators are not jumping to any conclusions.

"My heart is broken," she said. "The life that I knew is over, and all I can think is how scared she must've been."
