An elderly deaf man has died in Columbus, Ohio from injuries he suffered when he was beaten and robbed last month. 83-year-old Paul Earhart had been in a coma since the attack. Prosecutors say DNA from under his fingernails and eyeglasses could put his assalant behind bars. Police have already arrested one man for the crime: Jason Frost. They say Frost drove the getaway car, but another man was also involved in the attack. Earhart lived in an apartment complex for the deaf after having worked for many years at the Ohio School for the Deaf.
