On May 8, someone vandalized the outside of a Madison office building. They broke a window and started a fire in the office of Wisconsin Family Action, an anti-abortion rights group.
Hours later, Madison police called it “targeted” arson.
Since then, investigators have been trying to figure out who did it, and on Tuesday, they made their first arrest.
A criminal complaint said investigators connected Hridindu Roychowdhury to the scene with DNA.
The document said they found his DNA on several pieces of evidence, including a Molotov cocktail and the ignition wheel and button of a lighter.
Investigators said they then got a sample of Roychowdhury’s DNA after he threw away a partially eaten burrito earlier this month.
