SAN DIEGO — Oregon State Police said it has received 134 tips reported to the Amber Alert tip line since Wednesday's alert in Oregon for two missing California children.
In some cases, vehicles that matched the suspect's car were stopped but were determined to not be the suspect or the children. So far, police have not received any solid leads.
The Amber Alert was activated in Oregon and Washington Wednesday for two children last seen August 3, who may be traveling with a 40-year old man from southern California. It was then extended Thursday into Nevada.
The man, James DiMaggio (pictured below), is also suspected of killing the children's mother. Her body was found in a burned house near the U.S.-Mexico border. Authorities believed the suspect is possibly traveling to Canada.
Oregon State Police launched a search plane and were flooding roadways with troopers in southern and central Oregon looking for a dark blue Nissan Versa with California plates 6WCU986.
The Oregon response is because of two possible sightings - one just south of the state line in Alturas, California. The second was about an hour north in Lakeview, Oregon.
"We've seen video of the vehicle that is similar in description but we can't get a good look at who is in the vehicle or a license plate on that vehicle," Lt. Greg Hastings of the Oregon State Police told Newschannel 8.

The Amber Alert was also extended to Nevada Thursday morning.
The father of the two missing children pleaded Tuesday for DiMaggio to turn himself in.
"Jim, I can't fathom what you were thinking," said Brett Anderson, addressing his short statement at a news conference to his friend DiMaggio, the subject of a growing manhunt. "The damage is done."
Anderson also pleaded with his missing daughter, 16-year-old Hannah Anderson, who authorities said was in grave danger, to run away from DiMaggio if she got the chance.
Anderson did not make reference to his 8-year-old son Ethan, who was also missing.
The remains of a child were found in the burned house with the children's mother, 42-year-old Christina Anderson. An autopsy was performed Tuesday, but authorities said it could still take a few days for DNA testing to determine if the child was Ethan.
"It is a possibility that it's Ethan," said sheriff's Lt. Glenn Giannantonio. "Right now we just don't know. And we're praying that it isn't Ethan."
The San Diego County Sheriff's Department has said DiMaggio and Christina Anderson had been in a close, platonic relationship.
Sheriff's officials referred to Brett Anderson, who arrived from out of town to talk to investigators Tuesday, as her ex-husband, but he told The Associated Press that the couple had still been married.
On Sunday night, authorities found Christina Anderson's body near a dead dog when they extinguished flames at the rural home of DiMaggio in Boulevard, a remote hamlet 65 miles east of San Diego.
An Amber Alert advised freeway motorists, television viewers and mobile phone subscribers about a dark blue Nissan Versa with California license plates that DiMaggio was believed to be driving. The California Highway Patrol said the suspect could be headed to Texas or Canada.
The FBI joined the search and the Amber Alert was later extended to Mexico's Baja California state, which borders Boulevard.
Monday marked the first time that mobile phone users were notified of a statewide Amber Alert in California through their phones, CHP spokeswoman Jamie Coffee said. The alert system, which was introduced in December, sends messages automatically, based on the phone's location, not the phone number.
Christina Anderson grew up with her mother and stepfather in the east San Diego suburb of Santee, and she aspired to a career in child psychology, said her ex-husband, James Chatfield of La Grande, Ore. The marriage lasted four years, until 1992, and Chatfield said he lost touch.
"She was a high school sweetheart," he said. "It was a marriage of convenience that just didn't work out."
Chatfield said he helped Anderson's current husband move to The Dalles, Ore., in the early 1990s, but they lost contact.
