Cellphone sex video linked to New Year's Eve shooting

It started over a sex tape. It ended with a murder.

Marcus Hume wanted Steven "Sam" Moore dead because of a homemade video on Moore's cellphone, according to testimony on Thursday in Yuba County Superior Court.

William V. Silliman told police about Hume's desire to get the video away from Moore, Marysville police Detective Donald van Doorn testified Thursday.

Silliman heard Hume make several threatening statements about Moore, van Doorn testified.

"'I'm going to kill this fool,'" Hume told Silliman.

Moore, 38, was gunned down Dec. 31 in front of an Arthur Street apartment where he had been staying for a short time.

The trial against Silliman entered its second day Thursday. He has pleaded not guilty to a second-degree murder charge. Silliman, 21, faces 20 years to life in prison, if convicted.

Silliman talked about the tape during a five-hour police interrogation the day Moore was killed. Prosecutors played a portion of the police interview for the jury. "Marcus was really ticked off," Silliman told police.

Moore's family has said Hume killed Moore over a woman.

According to testimony on Wednesday, Hume and Moore were discussing Roni Mulkey moments before the fatal shot was fired.

Two of Mulkey's siblings, Kari and Samson Mulkey, were co-conspirators in Moore's death and have already admitted their roles after cutting deals with prosecutors.

Roni Mulkey, 19, could not be reached for comment on Thursday. She has been in custody without bail at the Yuba County Jail since Sept. 4 on an unrelated assault charge.

In addition to Kari Mulkey and Samson Mulkey, co-defendants Jesse Garate, David Eneix and Hume have also admitted their roles in Moore's death.

Samson Mulkey, Garate and Eneix accepted plea deals with prosecutors in exchange for their testimony.

Eneix and Garate testified Thursday morning and Samson Mulkey testified Wednesday.

Silliman told police that Hume wanted Kari Mulkey and others to help him get the illicit footage, van Doorn testified.

Silliman told detectives he owned the sawed-off 12-gauge shotgun and that he knew Hume had the gun when they left together to confront Moore, van Doorn said.

On the interrogation video, Silliman demonstrates to detectives how Hume concealed the weapon inside his jacket.

"I didn't know he was going to do anything with it," Silliman told police.

Prosecutors concluded their case Thursday.

Several key defense witnesses are not available to testify until next week and the trial in on hold until then.

Judge Julia L. Scrogin ordered the jury of seven men and five women to return to court Tuesday.

Silliman remains in custody without bail at the Yuba County Jail.
