The San Bernardino County Sheriff's Department suspended ground and aerial searches in the Big Bear area Friday night due to the weather. The manhunt resumes at 7 a.m. Saturday. But a noon press briefing has been cancelled.
As of 10:10 p.m. Friday, an LAPD spokesman said there was no update on the investigation.
Sightings of Dorner were reported Friday night but were either unfounded or didn't lead to the fugitive.
One sighting was at a Palm Desert rest stop. Riverside County Sheriff's deputies made a traffic stop and determined it wasn't Dorner.
In Los Angeles, LAPD police searched a train at the Amtrak yard by 8th Street and Santa Fe Avenue after a worker reported seeing a black man leaning out of a door of a train at 7:57 p.m.
LAPD Lt. Lee McMillion said the train, which came in from Riverside, was supposed to be empty.
"All he saw was the head and part of a shoulder," McMillion said.
The worker notified Amtrak police who checked the train and called the LAPD.
McMillion said officers searched the nine rail cars but didn't find anyone.
Dorner's deadly rampage has claimed three lives this week including that of a Riverside Police officer.
The 33-year-old former LAPD officer claimed in an online manifesto that he was unjustly fired by the LAPD in 2008 for making false statements. He filed a complaint against his training officer alleging she kicked a suspect who was mentally ill in the head and shoulder in 2007.
In the same manifesto, Dorner wrote about bringing "unconventional and asymmetrical warfare" to LAPD officers, listed LAPD personnel he blamed for the loss of his job and threatened to go after them and their families.
"You will now live the life of the prey," Dorner wrote.
He is suspected of killing 28-year-old Monica Quan and her fiance, 27-year-old Keith Lawrence. Police found the couple shot to death Feb. 3 in Lawrence's vehicle which was in a parking structure near their Irvine home.
Quan's father is a retired LAPD captain who represented Dorner in the disciplinary hearings.
On Thursday, police said Dorner shot at LAPD officers in Corona who were assigned to protect one of the people named in the manifesto. One of the officers sustained a graze wound to the head.
Dorner then turned up in Riverside and allegedly opened fire at two Riverside police officers stopped at a light. One officer was killed and the other was wounded.
The manhunt for Dorner has included federal law enforcement agencies.
"Customs and Border Protection officers and agents from the Office of Field Operations, the U.S. Border Patrol and the Office of Air and Marine are providing assistance in the search as requested from law enforcement authorities," said Mike Milne, spokesman for Customs and Border Protection.
