FBI releases victim sketches drawn by jailed serial killer

The FBI has released images of women supposedly killed by a US serial killer in a bid to bring justice to the victims.

The depictions were drawn by Samuel Little who is currently incarcerated in Texas for the murder of three women - but claims he is responsible for the deaths of many more.

Over the past few decades, the 78-year-old has confessed to more than 90 murders, leaving authorities following up on a series of trails across the United States.

Little reportedly said he is unable to remember the dates of the claimed killings, but says he can recall how he committed the murders, the car he was driving and the place that the crimes were committed.

Chillingly, Little is also able to remember the appearance of all the women he claims to have taken the lives of.

The FBI says Little preyed on vulnerable women, including those with drug problems and women working in the sex industry.

It says that the release of information could bring new details on a series of cold cases that it hopes to close.

Previously, Los Angeles detectives conducted a major cold case review after Little's arrest for the murder of three Los Angeles women in the 1980s.

The FBI said that Little, who has a criminal record dating back to 1956, "may be among the most prolific serial killers in US history".

Despite ill-health, it is expected that he will remain behind bars for the rest of his life.
