A heavily armed man accused of carjacking a Rohnert Park man at gunpoint Monday may be the same man Oregon authorities suspect killed a woman in Oregon on Sunday, leaving her body along Highway 101.
The suspect, Jeffrey Griffin Boyce, 30, of North Bend, Ore., had more than 200 rounds of ammunition and at least two rifles — an AK-47 and a .22 — and a .45-caliber handgun, said Rohnert Park and Central Marin police.
The Associated Press reported that Boyce is believed to be the suspect wanted by Oregon authorities investigating the death of a woman Sunday in Douglas County. The woman's body was found at Winchester Wayfinding Point, located along Highway 101 about 3 miles south of Reedsport.
In a news release Tuesday, the Oregon State Police said that a suspect in that case was arrested Monday night in California, and that two of its detectives have traveled there to interview the suspect.
Separately, Lt. Jeff Taylor of the Rohnert Park Department of Public Safety said detectives from Oregon are interviewing Boyce, who is being held in a Marin County jail after his arrest Monday evening.
Local authorities would not confirm Tuesday whether Boyce was the suspect in the Oregon death, but Rohnert Park police said Tuesday that a 63-year-old Rohnert Park man and 52-year-old Mill Valley woman who crossed paths with Boyce on Monday may have been saved by their cool handling of potentially life-threatening situations.
“There's no reason that these two victims are alive ... other than they kept super calm and they didn't agitate him,” said Rohnert Park Police Sgt. Aaron Johnson.
Boyce may have been headed to San Francisco to the Russian consulate, where he wanted to seek asylum, according to San Francisco police officials. They'd gotten that warning from Boyce's mother, Diane Boyce, who called the department Monday.
“She had indicated that he had talked about the recent bombing in Boston, as well as Colorado, and Columbine,” San Francisco Police Capt. Greg McEachern told KPIX TV.
“She didn't say he had a history of mental illness, she just said that in the last couple of weeks he'd become extremely unstable and was ranting about the government, and she was concerned for him,” McEachern told KPIX.
“It sounds like this guy was on a path of destruction,” Johnson said.
Police agencies Tuesday released further details of the incidents, outlining what must have been terrifying confrontations between Boyce and his two victims.
Police said Boyce carjacked and kidnapped Rohnert Park resident Valentino Sabuco on Monday afternoon before driving the man's car to Marin County. There, he tried to carjack Tina Humphrey, 52, of Mill Valley from the Bon Air Shopping Center in Greenbrae, officials said.
At about 4:20 p.m. Boyce followed Sabuco as he walked to his station wagon, parked at Mountain Shadows Plaza on Golf Course Drive.
Boyce rapped on the driver's window with the semi-automatic pistol, ordering the resident to move to the passenger seat.
With the gun pointed at him, Sabuco refused. Boyce then ordered him to drive, telling him to head for the nearest church, Johnson said.
Sabuco took him to St. Elizabeth Seton Catholic Church on Snyder Lane, but no one was there. Boyce ordered the man back to the plaza, where the suspect had left his Oregon pickup.
Boyce began loading guns and ammunition from the truck to the BMW, Johnson said.
Sabuco saw his chance and ran. He headed for a nearby Subway sandwich shop.
“He came in and he just said 'call 911, call 911 I got carjacked,'” said Subway employee Jason Sullivan, 25, of Rohnert Park.
“The guy who jacked the car said he needed to go to San Francisco and pulled a gun on him,” Sullivan said he was told.
Sabuco was upset and the incident scared Sullivan. “You never know what could happen. People are crazy sometimes.”
Boyce drove the station wagon to the Greenbrae shopping center, where he drove up to a parked Toyota Tacoma pickup. The woman was getting into the truck.
“The suspect pointed a gun at her chest ... told her to move over to the passenger seat,” Jervan said. “She told him 'no' and she started talking to him.”
Humphrey told KPIX she talked with Boyce for 15 minutes before a passer-by called 911 and the suspect fled on foot after he heard sirens.
“When he heard the sirens he said, 'you shouldn't have done that ... I'm going to take you out.' And I said, 'What would that prove?'” Humphrey told KPIX.
An off-duty Central Marin police detective arrested Boyce at gunpoint a short time later, finding the suspect attempting to get into a Greenbrae home.
Boyce had a loaded handgun in his front left pants pocket, according to Sethi Jervan, a Central Marin police corporal.
During the arrest, Boyce put his hands to his waistband, near the gun, and Detective Mike Mejia continued to yell for the man to drop to the ground and he finally complied, Jervan said.
The AK-47 was found at the nearby shopping center, in a BMW station wagon that had been stolen from the Rohnert Park man, police said. The other rifle was in Boyce's truck left in Rohnert Park.
Boyce was booked into the Marin County Jail without bail, suspected of six felony crimes involving the attempted armed carjacking.
Rohnert Park police were expected to add at least three felony charges against him in connection with the carjacking from Mountain Shadows Plaza.
Boyce's father, Griffin Boyce of Southern California, said Tuesday he wasn't aware of his son's arrest.
He said his son was a bright man who may suffer from mental health issues. They hadn't spoken in about six months, he said.
“I was led to believe he was taking some medication. To the best of my knowledge he was living with his mother and looking for work,” Griffin Boyce said. “I don't know anything about him having guns. I'm sorry to hear that.”
Rohnert Park detectives Tuesday night were expected to search the truck and car.
Oregon State Police also were investigating Boyce's actions in that state, Rohnert Park Lt. Taylor said.
“We're just happy this guy is off the street,” Taylor said.
