The display was the only student structure in an annual "Canstructure" competition, which raises food donations for the Food Bank of Alaska. Architecture and engineering firms entered a dozen other entries.
Anchorage police say the suspects slammed their bodies into the display Sunday night and fled. Two suspects are from Dimond High. The third is a home-school student. Police forwarded vandalism charges on all three to juvenile authorities.
The food was valued at $2,300. Many of the cans were damaged. The food bank is evaluating whether damaged cans can be accepted.
