STOUGHTON, Wis. -

Stoughton police said a DeForest man was arrested for sending a threatening letter to a Stoughton family in April.

Matthew J. Cimaroli, 21, was arrested Sunday on suspicion of felony threats to injure or accuse with a hate crime enhancer. He’s expected in court Monday.

Police said Cimaroli sent a letter sent to the Hale family depicting the lynching of two young black men in a historical textbook photo. The letter had typewritten wording of “Your Days Are Numbered,” police said. The threatening letter was directed toward a member of the family.

Cimaroli told police he sent the letter because he was upset over a theft of money from a drug transaction.

Cimaroli was identified as a suspect in May but investigators said they needed to wait for forensic evidence to be processed.

The Wisconsin Department of Justice, FBI, and the U.S. Postal Service assisted in the investigation.
