Honolulu is a major financial center of the islands and of the Pacific Ocean. The population of the city of Honolulu was 337,256 as of the 2010 census, while the Honolulu CCD was 390,738 and the population of the consolidated city and county was 953,207.

Q: story: A man has been charged with a federal hate crime in connection with what authorities say was a racially motivated "knockout" assault against an elderly black man, the U.S. Justice Department said Thursday. 

Conrad Alvin Barrett, 27, of Katy, Texas, has been charged with one count of violating the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act. 

According to the federal complaint, Barrett attacked the 79-year-old man "because of the man's race and color." He will next appear in court Friday afternoon for a detention hearing. 

The suspect made a video of the attack November 24, the complaint said. In the video, he allegedly commented that "the plan is to see if I were to hit a black person, would this be nationally televised?" 

He then allegedly "hit the man with such force that the man immediately fell to the ground. Barrett then laughed and said 'knockout,' as he ran to his vehicle and fled." 

The victim suffered two jaw fractures and was hospitalized for several days, the complaint said. 

Barrett's attorney, George Parnham, told CNN the affidavit does not "pull back the layers of mental health." 

His client has bipolar disorder and takes medication, Parnham said in an earlier call. 

Parnham said he could not state whether his client carried out the attack, but, "mental health issues definitely played a part in anything that occurred." 

Barrett "is very sorry for this person," Parnham said, adding that he and his client haven't had much opportunity to discuss the facts of the case. , question: What is the name of the attacker?
A:
Conrad Alvin Barrett
