The suspect allegedly beat the driver into a coma in Brooklyn over an argument about the fare.
The victim's sister and nephew are demanding justice for him.
53-year-old Key Chun Kim had been in a coma since New Year's Day.
Officials believe the gentle New York City yellow cab driver was beaten unconscious by a violent passenger who asked for a ride out to Willoughby and Skillman in Brooklyn then refused to pay his fare.
Kim's family by his bedside at Kings County Hospital asked Eyewitness News to protect their identities.
They are fearful of the passenger.
28-year-old Andrew McElroy was arrested shortly after savage attack then charged only with only misdemeanors.
The day after the near fatal beating he was released on $10,000 bail while Kim has still to open his eyes.
The family worries officials are taking Kim's life too lightly.
He drove a cab by night to pay the bills.
By day, he was a published author.
He wrote poems and played golf.
In fact, Kim was about to complete a collection of Korean poems when his world collapsed.
