At various times during the day, Christopher Dorner was spotted near the Twin Towers Correctional Facility; in a white Lexus on the edge of the desert outside of Barstow, and driving on the San Gabriel River (605) Freeway near the very suburban community of Pico Rivera.
Although a massive manhunt concentrated 100 law enforcement personnel searching for the muscular 6 foot, 270 pound black man in the snow covered San Bernardino Mountains near the ski resorts of Big Bear, black men of similar builds throughout the region generated phone calls to law enforcement.
For example, El Monte police responded to a reported Dorner sighting about 10 a.m. at Peck Road and Valley Boulevard, Lt. Dan Burlingham said.
"We had a report, it was of a person matching the description with a police-type shirt on walking across the street," he said.
Upon investigating, officers determined the man was a security guard in the area just picking up his lunch.
Pasadena bail bondsmen Ishmael Trone urged law enforcement officers and black men to be cautious while Dorner remains on the loose.
"You can't recklessly stop African Americans," Trone said. "We still have to insure that citizens believe the police are there to protect and serve. We should not ignite fear in the African American community."
With tensions running high, Trone said black men should avoid even the most banal confrontations with the police.
"Make sure you have your identification make sure you cooperate with the police; now is not the right time to wear a hoodie," Trone said.
And the threat from amped up police officers extends beyond the black community. Two Latina women in Torrance were shot by officers who thought their car looked like the one driven by Dorner. The car did not match the description.
"That's a tragedy, and the police department needs to be held accountable for that, including from a financial perspective," said Joe Brown, former Pasadena-branch NAACP president.
Despite the admonitions and abundance of caution, fear brought Dorner sightings from Ventura to San Diego and a whole host of locations in between.
Sightings were also reported to police in Ontario, Rancho Cucamonga, Irwindale and Long Beach at various times since Thursday. None panned out.
Officers who normally patrol solo were put two-officer cars at police departments in Los Angeles, Pasadena, South Pasadena and Monrovia, as well as the Los Angeles County Sheriff's Department, officials said.
And many departments also beefed up patrols at sensitive locations such as schools.
Near Pico Rivera, someone reported seeing a large black man wearing military fatigues and driving a royal blue car about 6:30 a.m. on eastbound Telegraph Road, Sheriff's Lt. Robert Smith said.
"We checked it out. We looked at (surveillance) video," Smith said. "We didn't find anything."
Another motorist called deputies about 11 a.m. Thursday to report seeing a man who resembled Dorner driving a gray Aspen SUV eastbound on Slauson Avenue near Pioneer Boulevard, Smith said.
Again, deputies investigated but found no signs of Dorner.
Farther south in San Diego County sheriff's deputies remained at the Barona Indian Reservation early Friday after someone called to report seeing Dorner at a residence around 10:15 p.m. Thursday. The report appeared to be false.
For the most part, "It's all unfounded," said Jodi Miller, a spokeswoman for the San Bernardino County Sheriff's Department.
Unfounded or not, law enforcement agencies didn't let their guard down.
The Twin Towers Correctional Facility in Los Angeles went on lockdown, and an area search launched, after a civilian employee reported to her supervisor about 8:45 a.m. that she saw "somebody outside who resembled suspect Dorner," Los Angeles County Sheriff's Department spokeswoman Steve Whitmore said.
"Out of a preponderance of caution, we locked down the facility as well as the streets in front," Whitmore said.
Officials continued trying to identify the person the civilian jail employee saw, Whitmore said, but added it was "very possible" it was not Dorner.
