Dickinson Trinity High principal Thomas J. Sander, who was in his first year at Trinity, was arrested Tuesday in connection with a fire early Monday morning at the school.

UPDATE, 3/5/14 (2:30pm): Sander is being held on $500,000 cash bond. Judge Dann Greenwood cited the crime's severity, Sander's lack of ties to Dickinson, and the "dramatic impact" to the community as reasons for the high bond.

Thomas J. Sander, 30, was arrested after an interview with police revealed information that led to the charges of arson and endangerment by fire.

Sander has been charged with Class B felony charges of arson and endangerment by fire. Both maximum penalties of 10 years' imprisonment, a fine of $20,000, or both.

The fire caused significant damage to the school, rendering the building unusable for the foreseeable future. Classes have been canceled for the remainder of the week and will move Dickinson Public Schools and facilities at Dickinson State University. The girls basketball tournament that was scheduled to take place at Trinity has been moved to Dickinson High.

The Dickinson Catholic Schools President said in a text message to the Dickinson Press that "Trinity High School will not be open the rest of the school year."

A fire relief fund has been set up for Trinity High. The amount needed to be raised has yet to be determined, but it is expected to be significant.
