Former White House Press Secretary James Brady's death has been ruled a homicide, The Washington Post and USA Today reported on Friday.

Brady, who served during Ronald Reagan's administration, was wounded during an assassination attempt in 1981.

After becoming a gun control activist, he died this week at 73.

His death was ruled a homicide by the Virginia medical examiner's office, The Post reported.

John Hinckley Jr., who was found not guilty by reason of insanity in the shootings of Brady and Reagan, could be charged with murder, USA Today reported.
