Police eventually arrested 24-year-old Casey Wentworth of Portsmouth on Monday and charged him with burglary. He's accused of taking the laptop from Witonis' home in Dover in February 2013.
When the break-in happened, police said they couldn't identify any suspects. Detectives contacted Apple and the laptop's serial number was flagged.
When Witonis got the email, he contacted police, who said the person who called customer service used the serial number of the stolen computer.
Witonis tells a local television station that the discovery was sort of shocking.
Wentworth is scheduled to be arraigned on May 2. It wasn't immediately known if he had a lawyer.
