One of the emails, sent Dec. 20, to Pai’s government and personal accounts had the subject line “Cheers.” The body of the email listed the names and addresses of three preschools in and around Arlington, Va., where Pai lives, followed by, “I will find your children and I will kill them,” according to the affidavit against Man.

The FBI traced the emails to Man’s home and confronted him in May 2018. Man acknowledged sending the email that threatened Pai’s family, and said he used the address “[email protected]” to hide who he was and because he thought the handle sounded “tougher,” the affidavit said.
