But in the end, it was a police officer and a sheriff's deputy from the Inland Empire who paid the ultimate price for Dorner's wrath.
Dorner is suspected of fatally shooting a San Bernardino County sheriff's deputy and seriously injuring another Tuesday during a gunbattle with police in the frigid San Bernardino Mountains. He is also suspected of fatally shooting Riverside Police Officer Michael Crain and wounding his partner with a sniper rifle on Feb. 7.
"Bad guys don't know any jurisdictional boundaries. This was a sick person who just had anyone who wore a badge in his sights," San Bernardino County Board of Supervisors Chairwoman Janice Rutherford said Tuesday. "It's a tragedy no matter what color uniform or jurisdictional patch the officers wore on their sleeves."
Supervisor James Ramos, whose district the deadly gunbattle between Dorner and sheriff's deputies occurred before reaching a tragic conclusion, said Tuesday's incident was just one in a series of crises that have occurred in his district in the last two weeks.
Ramos cited the fatal shooting of Officer Crain in Riverside, which drove Dorner into the San Bernardino Mountains, where he set his pickup on fire in the parking lot of the Bear Mountain ski resort before fleeing, prompting a massive manhunt.
And Ramos said the deadly Super Bowl Sunday bus crash on Highway 38 near Yucaipa, just a few miles south of where Tuesday's shootout occurred, is still fresh in the minds of most. Eight passengers were killed and 20 others injured during a day trip to Bear Mountain for skiing and snow play.
"We stand united with that deputy and all our law enforcement family in this crisis that has spread from Los Angeles to Riverside and ultimately to the San Bernardino Mountains," Ramos said.
Dorner fled to the mountains following the shootings last week in Riverside, which followed an incident about 30 minutes earlier in Corona in which Dorner allegedly fired shots at two Los Angeles police officers who were guarding one of Dorner's intended targets. One of the officers was grazed in the head and the other was not injured.
The Dorner manhunt had law enforcement across California on edge, fearing for their safety and the safety of their families.
Dorner's first alleged victims were the daughter of retired Los Angeles police captain-turned lawyer Randal Quan of Walnut, who represented Dorner during Dorner's board of rights hearing in 2007.
Monica Quan, 28, and her fiance, Keith Lawrence, 27, were found shot to death inside their vehicle in the parking structure of their Irvine condominium on Feb. 3.
Law enforcement officials across Southern California banded together in their efforts to stay secure and assist in the capture of the fugitive. An unprecedented $1 million reward was offered for information leading to the arrest and conviction of Dorner.
The material impact to the San Bernardino Police Department was minimal -- officers went to Riverside after their officers were fired upon on Thursday to handle secondary calls and free up that department for the manhunt, then focused mostly on passing along information -- but the emotional toll was larger, said Lt. Paul Williams, a department spokesman.
In addition to the tension that comes with having a man believed to be targeting police in the area over the last several days, Williams said he and other officers knew the deputy who was killed Tuesday.
He was a good man, Williams said.
"In 21 years of law enforcement, unfortunately, you meet a lot of good people," Williams said. "Our hearts and prayers go out to his family and those that worked on this tragic case."
At Loma Linda University Medical Center, reporters gathered, keeping vigil and waiting for news of the two injured sheriff's deputies, wounded when they exchanged gunfire with Dorner.
The medical center parking lot was representative of the multiple law enforcement agencies giving of themselves.
When the death of one of the deputies was confirmed, Jodi Miller, sheriff's spokeswoman, fought back tears.
Two new candles were placed in front of the hospital, near the ER, a simple but poignant symbol of the two most recent victims.
The weeklong ordeal had left four people dead - two of them Inland Empire law enforcement.
The manhunt showed that Inland Empire agencies were among the finest in the country, said Brian Levin, a professor of criminal justice at Cal State San Bernardino and former New York Police Department officer.
"If there's a positive side to this terrible tragedy, I think it did show just how incredibly professional and brave our law enforcement is in the IE," Levin said. "We live in an LA-centric area, but when a bad guy's on the loose... you couldn't have had a more brave or professional response."
Levin said the events would likely be studied for future training, and those involved would be remembered alongside a handful of others.
"It brings back to memory the North Hollywood shootout, for instance, or 9/11, where there are these kinds of incredibly dangerous and somewhat unusual circumstances that I can't tell you how impressive they are."
"In the police world, these heroes, they stay as part of the family," he said.
The effects of the Dorner manhunt also extended to the residents of the sleepy town of Big Bear, where one resident said "you can't go into a grocery store without recognizing someone."
Local resident Theresa Vazquez, 55, said her daughter lives just 15 houses away from the house where Dorner's alleged hostages were found. Her 6-year-old grandson attends kindergarten at Baldwin Lane Elementary School, which was locked down multiple times during the Dorner manhunt and was home to armed guards leading up to Tuesday's standoff.
"To think (Dorner has) been up here this whole time, everybody has been really on edge, taking extra precautions, making sure everybody is home safe and doors are locked and kids are safe," Vazquez said.
Tuesday's events also hit home for Vazquez, who said she and others in the community were worried that the officer who was confirmed dead by San Bernardino County sheriff's officials could be one of their own.
"Being so close, being locked down again, those things just don't happen up here in Big Bear, that is something you read about happening elsewhere," she said.
Redlands Mayor Pete Aguilar said it is very rare someone loses their life in the line of duty and it was important to work together in these difficult times.
"The city of Redlands sends our support and thoughts and prayers," he said.
