Since a photo and a team logo were on the side and back of the trailer, the people who took the van had to know what it was used for, team officials said.
Gwinnett schools official Mike Phillips, who works with the Heat, said police are investigating, and officials are trying to get a new trailer.
Also, a GoFundMe site has been set up to raise funds to buy a new trailer.
But Phillips noted the effect the incident had.
“You just don't really know,” Phillips said, “the impact you had on a bunch of kids who overcome adversity every day.”
