Man Held in Attack on Denny Faces New Charges : Riots: Damian Monroe Williams is to be accused of assaulting and robbing a good Samaritan near site where trucker was beaten. Suspect will have total of 19 counts against him.

Damian Monroe (Football) Williams, who has been accused of attacking truck driver Reginald O. Denny and other motorists on April 29, will also be charged with beating and robbing a good Samaritan who attempted to help another riot victim, prosecutors said Wednesday.

“We believe that there is sufficient evidence to charge Mr. Williams with attacking somebody who was coming to the aid of Mr. (Takao) Hirata,” said Frank E. Sundstedt, head deputy district attorney in charge of the organized crime and anti-terrorist division. The victim’s name was not released.

According to police reports, Hirata was one of the first people attacked at the intersection of Florence and Normandie avenues when violence erupted in the early hours of the Los Angeles riots.

Hirata, police say, was driving his 1986 Ford Bronco southbound on Normandie. As he approached the intersection of Florence, Hirata was dragged from behind the wheel and beaten and his vehicle was stolen, police said.

Williams, who is in custody in lieu of $580,000 bail, will be arraigned on charges of robbery and assault Monday, bringing to 19 the number of counts against him. He is accused of beating or robbing eight people.

The decision to file additional charges against Williams came as a key court date for him and two other suspects approaches. Williams, Antoine Eugene Miller and Henry Keith (Kiki) Watson are scheduled to appear in court July 31 for their preliminary hearing, where Municipal Judge Larry P. Fidler will decide whether there is probable cause to hold them over for trial.

Williams, who was in court when prosecutors announced their intention to file the additional charges, showed no emotion.

His lawyer, Dennis Palmieri, said he would not comment on the new accusations, but added later that they “may be excessive. The prosecution may be on a fishing expedition.”

As lawyers prepare for the preliminary hearing, Fidler also ordered prosecutors in the case to turn over to Palmieri any videotapes that could be relevant. Many videotapes have been made available to defense lawyers, but Palmieri asked to see them all and Fidler ordered the prosecution to comply.

Palmieri also said he was led to believe there could be a second audiotape of Williams being interviewed by police. Prosecutors already have turned over one interview tape, but Palmieri told the judge that Deputy Dist. Atty. Lawrence C. Morrison had hinted there could be another.

Palmieri has accused prosecutors of misleading him, and as a result, the district attorney’s office now declines to communicate with him except in court or in writing.

Sundstedt said there is only one tape of Williams being interviewed and told the judge that “any other tape that is the product of Mr. Palmieri’s imagination is just that, a product of his imagination.”

In the recording already submitted, Williams is heard being read his rights and acknowledges participating in the beating of Denny. Palmieri, who claims his client was promised leniency in exchange for his cooperation, said Wednesday that he will move to exclude the tape from evidence.

He added, however, that news reports of the tape--especially excerpts of it reported by The Times--already have prejudiced the case against Williams.

“I do not believe it is possible for my client to get a fair trial,” Palmieri said.
