More arrests in Gustine slaying

Four more men are in custody on suspicion of being involved in the fatal Nov. 6 stabbing of 33-year-old Bill James at a Gustine bar. That brings the number of jailed suspects in the case to eight.

Suspects Rafael Valdez, 26, Anthony Oseguera, 24, and Albert Aleman, 36, were arrested separately at Southern California locations in late November and December, according to the Merced County Sheriff's Department. Suspect Brandon Carvalho, 30, was arrested recently in the San Jose area.

Witnesses told sheriff's investigators that James was stabbed by members of the Mongols, an outlaw motorcycle gang with chapters worldwide, according to a sheriff's report.

Although detectives believe the suspects are members or affiliates of the gang, they have no indication James was gang-affiliated.
