BOSTON (KABC) -- Boston Marathon bombing suspect Dzhokhar Tsarnaev wrote an email to his mother that he expected to die just hours before a gunfight with Massachusetts police.
He wrote "he loved her and ended with, 'Inshallah (i.e. God willing) if I don't see you in this life I will see you in the akhira (i.e. afterlife),'" according to court documents.
Federal prosecutors included the email in a court document filed Monday in response to a motion by Tsarnaev's lawyers to suppress evidence collected from his computer and his family's apartment.
In sending the email, Tsarnaev left his apartment and didn't expect to return home alive, and "thus abandoned his expectation of privacy in everything left behind," prosecutors said.
Defense attorneys said Tsarnaev had a reasonable expectation of privacy. The search warrant was too broad and vague, they said.
Prosecutors also claim that Tsarnaev's belongings at his apartment couldn't be kept from authorities, because he had moved into a dorm room at UMass-Dartmouth, wasn't paying rent at the apartment and wasn't on the lease.
Tsarnaev, 20, has pleaded not guilty to 30 charges for allegedly placing pressure cooker bombs with his brother near the Boston Marathon's finish line, which killed three people and injured more than 260 others last April.
His brother Tamerlan Tsarnaev was killed in a police shootout four days after the blast.
