After gathering in the gym, the large group of students moved outdoors and released dozens of pink balloons in honor of their fallen friend.
Nalepa was in the back seat of the family's 2009 Ford Expedition when it was rear-ended on April 6 on FM 518. She was taken off life support two days later.
The force of the impact caused the driver's seat to fail, her family attorney said.
"The seat collapsed backwards and went backwards into her and her head hit the back of the seat," said Alton C. Todd, an attorney representing the Nalepa family.
Nalepa's mother and father are suing Erika Diebel, who was arrested last week after blood alcohol tests measured her at .249 at the time of the wreck - more than three times the legal limit, according to investigators.
The Nalepa family has also named Ford Motor Company in the suit, alleging negligence in the Expedition's design and manufacturing, calling the seats dangerous.
"It's our feeling that child safety is everybody's responsibility. Our children (are) depending upon us," the family's attorney said.
