"We really just want him to be safe," said his brother, Avicenne Nasr.

What they're saying:

Avicenne Nasr flew home from college at Virginia Tech to help his parents find his best friend, his little brother Allister.

"We’re really concerned about his safety and his overall mental well-being during this time," Avicenne Nasr said.

As a high school senior, Allister is supposed to graduate in a few months and then attend the University of Florida to study engineering.

St. Pete Detectives said they have traced cell phone data and used drones to search a wooded area behind Canterbury School near Shore Acres.

Zach Nasr is at school in Colorado and sent a message to Allister, telling him how much he loves him.
