Serial Killer Samuel Little has made portraits of 16 of his victims who remain unknown.
The bureau told CNN they hoped "someone - family member, former neighbor, friend - might recognize the [victims] and provide the crucial clue in helping authorities make an identification". "We want to give these women their names back and their family some long awaited answers. It's the least we can do", Buchwald added.
Buchwald said the strategy has worked before, with women who appeared in two previously released portraits being identified.
Four of the six South Florida victims were killed in Miami, one in Homestead and another in Kendall.
The victims are all captured in the final moments of their lives and most exhibit forlorn or petrified expressions, staring directly into the killer-come-artist's eyes. Little is serving three consecutive life sentences with no possibility of parole.More news: 5 talking points from Tottenham Hotspur’s 3-0 win over Borussia Dortmund
The 78-year-old former competitive boxer last year confessed to committing 90 killings in the United States since the 1970s.
In May, Little rattled off details of his alleged slayings to Federal Bureau of Investigation agents in exchange for a prison transfer, the agency said.
Officials have confirmed more than 30 of those killings, but they're still trying to corroborate little's claim. But starting last May, Little shared story upon story of the dozens of other vulnerable women - many of whom were involved in prostitution and addicted to drugs - who he claimed to have strangled to death, leaving a trail of bodies across the country.
One picture, for example, depicts a white woman with green eyes and brown hair aged between 20 and 25 years old who was killed in Maryland in 1972.
Holland was trained in cold cases and visited Little where he eventually gained his trust, Ector County District Attorney Bobby Bland told CNN. "Jackson, Mississippi-one; Cincinnati, Ohio-one; Phoenix, Arizona-three; Las Vegas, Nevada-one", Palazzolo said.More news: Spike Lee casts Chadwick Boseman in first film since Blakkklansman
Little's first confession was about the 1994 murder of Denise Christie Brothers in Odessa, Texas.
Authorities were able to place Little passing through the area at the time of the killing, and in exchange for a deal which moved him to a different prison, Little agreed to talk to investigators where he confessed to the murders.
However, more than half of his confessions are yet to be confirmed or matched to open cases.
