“He just got out of his coma. His eyes are open. His legs and arms are moving but his brain activity is not there,” Destinie Geisinger, the victim’s niece, said.

Deputies say Doffing, who’s an accountant, was on his way home on May 24 when four men jumped him on San Vicente Boulevard near an alley just north of Santa Monica Boulevard.

He sustained a traumatic brain injury as a result.

The reward from the city of West Hollywood is being offered for any information that leads to the arrest and conviction of those responsible.

“The brain damage that they did to him, especially on the back right side of his head, is extremely terrible,” Geisinger said.

No one is currently in custody, and authorities say the security video from that night has yielded no results so far.

“I don’t know what kind of people would do this to an innocent person. My uncle is the nicest, sweetest man in the entire world and justice is going to be served to them,” she said.
