AUSTIN (KXAN) — Balloons floated high into the Austin sky in honor of Cameron Nelson Sunday.

Nelson is the son of LBJ Early College High School’s head football coach Jahmal Fenner. According to a GoFundMe set up by the family, Nelson died in a “violent tragedy.”

On Monday, Pflugerville police said Nelson died in a Nov. 23 shooting.

The LBJ Athletic Department posted on its Facebook page, asking for those attending to wear different shades of blue.

The balloon release took place at Mueller Park at 4 p.m.

The GoFundMe is to raise money for funeral expenses. The organizer of the page wrote:

“Our beloved son, brother, nephew, and cousin Cameron Nelson was unexpectedly taken from us last Tuesday night. This violent tragedy has torn this family apart and more so during this holiday season, While the investigation is still ongoing there is not much we know at this time, Many have asked us what they can do and this platform will help. Should you like to help the family lay our beloved Cameron to rest here is how you can help honor his Life. Any amount, a prayer, or even a share is appreciated.”

Some of Cameron’s close friends want him to be remembered for his selfless personality.

“He didn’t hesitate to give you anything, he made sure to look out for you even if it left him without anything,” Julia Gomez said.

Another friend said Cameron was always positive.

“He would always just try to see the good in things,” Samantha Rodriguez said.

Nelson was 21 years old.

Fenner lead his football team to victory on Saturday night — just days after Nelson was killed. He dedicated the win to his son.

“I know that’s what my son would’ve wanted me to do, was to be here,” Fenner said. “He loved football, he loved LBJ.”

To feel true victory, Fenner is asking for one thing. “We want justice for Cam,” he said.

Nelson’s friends and family hope for this too.

“He knows that we love him deeply, and we’re always going to love him everywhere we go,” Gomez said.

Police are still investigating the crime. This story will be updated as we get more details.
