SIOUX CITY, Iowa (AP) – An 18-year-old Nebraskan has been given two years of probation after pleading guilty to vandalizing Sioux City’s Flight 232 crash memorial.

Felipe Sebastian, of South Sioux City, was convicted of criminal mischief. Judge Jeffrey Poulson deferred judgment, so if Sebastian successfully completes probation, the case will be cleared from his record.

Sebastian also was ordered to pay a $3,000 civil penalty, more than $1,500 in restitution and write an apology to the city of Sioux City.

Sebastian’s co-defendant, Scott Coleson, of Lehigh, Iowa, is scheduled for a plea hearing on Oct. 9.

Sebastian admitted damaging one of the pink quartzite boulders leading to the memorial on June 20. The memorial honors the 112 people who died in the July 1989 crash of United Airlines Flight 232 at Sioux Gateway Airport.
