3 Suspects Held in Roadside Slayings of 3 : 3 Suspects Held in Slayings of 3 in Chino Area

San Bernardino County sheriff’s deputies have arrested three suspects in the roadside slayings last weekend of two half brothers and a woman after a fistfight at a party near Chino, authorities said today.

The arrest Monday of Robert Clifton Marler, 21; his brother, Michael Wayne Marler, 18, and a 17-year-old youth, all of Chino, followed an intensive investigation and questioning of nearly 100 people who attended the party in nearby Los Serranos, San Bernardino County Sheriff’s Deputy Dana Williams said.

Richard Rayburn, 28; his half brother, Todd Moore, 23, and Rayburn’s girlfriend, Cynthia Rene Speers, 23, all of Chino, were gunned down Sunday night near their van, which was parked at California 71 and Pomona-Rincon Road, authorities said.

An unidentified 18-year-old Oklahoma man, who survived the attack by hiding on the floor, pulled the victims back into the late-model van and then drove to a gas station to call for help, Williams said.

Based on information provided by the survivor and party-goers, authorities were able to piece together the chain of events that may have led to the murders.

Fight Began at Party

Authorities said the juvenile suspect got into a fight with one of the victims at the party. The juvenile and Michael Marler then left the party and enlisted the help of Michael’s older brother, Robert Marler, “who supplied handguns for the three of them,” Williams said.

Together, they began searching the Los Serranos area for the victims.

The suspects opened fire when Rayburn and Moore exited the van, Williams said. Rayburn was shot once in the back, and his half brother was shot several times in the upper body, authorities said. Cynthia Speers, who was sitting in the driver’s seat of the van at the time, was hit once in the back.

Investigators later served a search warrant at the Marler residence in Chino and recovered six handguns, six rifles and ammunition, Williams said. He added that investigators are searching for additional weapons connected to the murders.

Williams said murder charges are being sought against the suspects.
