People drop off the list if they are captured, dismissed of criminal charges, or no longer fit the FBI's description as someone with "a lengthy record of committing serious crimes and/or considered a particularly dangerous menace to society."
When vacancies exist, the Criminal Investigative Division of the FBI asks its various field offices around the country to submit nominations for prospective additions. FBI executives ultimately approve who makes the top 10.
Here's who is on the list and how they got there.
Robert Fisher: added in June 2002, $100,000 reward
In 2001, the FBI says Fisher killed his wife and two children, then blew up their house in Scottsdale, Arizona.
The Bureau says Fisher is physically fit, and has a noticeable gold crown on his upper left first bicuspid tooth.
"He may walk with an exaggerated erect posture and his chest pushed out due to a lower back injury."
Fisher can be seen walking and carrying one of his children before committing the alleged massacre in this very grainy video from 2001.
Alexis Flores: added in June 2007, $100,000 reward
Flores is wanted for his alleged involvement in the kidnapping and murder of a 5-year-old girl in Philadelphia.
She was reported missing in July of 2000, and later found strangled to death in a nearby apartment that August.
He has scars on his right cheek and forehead, according to the FBI.
Jason Derek Brown: added in December 2007, $200,000 reward
Brown is wanted on charges of murder and armed robbery in Phoenix, Arizona. The FBI accuses him of shooting and killing an armored-car guard outside a movie theater and then fled with the money in 2004.
Brown, a Mormon, speaks fluent French and has a masters degree in international business.
He "enjoys being the center of attention and has been known to frequent nightclubs where he enjoys showing off his high-priced vehicles, boats, and other toys," according to the FBI.
Yaser Abdel Said: added in December 2014, $100,000 reward
Said is accused of murdering his two teenage daughters in 2008 in Texas.
He is originally from Egypt, but has ties to New York, Texas, Virginia, and parts of Canada.
The FBI notes some oddly specific details about Said.
"He always wears dark sunglasses, both indoors and outside. He frequents Denny's and IHOP restaurants and smokes Marlboro Lights 100 cigarettes," the FBI says.
Said also "loves dogs, especially tan and black colored German Shepherds."
Bhadreshkumar Chetanbhai Patel: added in April 2017, $100,000 reward
Patel, who is from India, is accused of killing his wife by hitting her repeatedly with an object while they were both working at a donut shop in Maryland in 2015.
He was charged with first and second degree murder, first and second degree assault, and carrying a dangerous weapon with intent to injure.
Patel fled in an effort to evade authorities, according to the FBI. He is last known to have been in the Newark, New Jersey, area.
Santiago Villalba Mederos: added in September 2017, $100,000 reward
Mederos is a member of the Eastside Lokotes Sureno gang, which is located in parts of Washington State, according to the FBI.
He is accused of killing a random 20-year-old girl and wounding her brother after shooting at them in their car in 2010.
A month later, the FBI says Mederos fired again at random bystanders, killing a 21-year-old man.
Alejandro Castillo: added in October 2017, $100,000 reward
Castillo fled the US after the FBI says he killed his ex-girlfriend and former co-worker in North Carolina.
US Customs and Border Protection surveillance video shows him crossing the border into Mexico from Nogales, Arizona, in August 2016.
The female victim's body was found in a wooded area in North Carolina with a gunshot wound to the head, according to the FBI.
Castillo previously lived in Charlotte, North Carolina, but has connections to Arizona.
Rafael Caro-Quintero: added in April 2018, $20 million reward
The Bureau says he helped form the Guadalajara cartel in the 1970s, which funneled heroin, marijuana, and cocaine into the US. Caro Quintero is wanted on charges of kidnapping and murdering US federal agent Enrique "Kiki" Camarena in 1985.
He's the only fugitive on the list that the bureau is offering a reward in the millions for — up to $20 million.
Arnoldo Jimenez: added in May 2019, $100,000 reward
In 2012, the FBI says Jimenez stabbed his wife Estrelle Carrera to death in his Maserati on the day of their wedding.
He then dragged her body into her bathtub in Illinois, before fleeing, according to the Bureau.
Carrera's family received a phone call from one of Jimenez's family members, saying they had gotten into a bad fight and he left her bleeding.
Jimenez may have fled to Santiago Papasquiaro in Durango, Mexico, according to the FBI. He's otherwise spent time in Reynosa, Tamaulipas, Mexico, and used to live in Chicago.
He also goes by the name Arnoldo Gimenez.
Eugene Palmer: added in May 2019, $100,000 reward
In 2012, Palmer is accused of shooting and killing his daughter-in-law Tammy Palmer in Stony Point, New York, according to the FBI.
Palmer's son John and Tammy had a messy separation. Palmer's relationship with Tammy grew increasingly tense, especially after she filed a restraining order against John.
After shooting Tammy, the FBI says, Palmer fled. His pickup truck was found in Rockland County.
Palmer is a car enthusiast, an experienced hunter, and an outdoorsman, according to the FBI. He has a deformed left thumb.
