Police in Washington, D.C., have attributed an unsolved murder from 1972 to convicted serial killer Samuel Little, just weeks after he admitted to committing at least 90 killings since the early 1970s.

Prince George’s County Police said Wednesday that officials received a call in October about an unsolved murder dating back to the summer of 1972, in which a hunter discovered human remains in a wooded area off Route 197, along the Baltimore-Washington Parkway in Laurel.

Officials said that a Texas Ranger informed them that Little had confessed to a murder in the Washington region that matched their case.

Detectives set out to interview Little in Texas, where he is serving multiple life sentences for murders in that state and California. According to investigators, he revealed “specific and previously unreported details” about the case that led them to believe his confession.

Police have never been able to identify the victim, but say Little’s confession has helped them to narrow their search.

The medical examiner’s report described the victim as a 19-year-old Caucasian female, with dirty blond or reddish hair. The victim was between 5-foot-2 and 5-foot-6.

Little told investigators he picked the woman up at a bus station on New York Avenue in the District of Columbia and learned that she was recently divorced and had come there from Massachusetts.

Nearly two weeks ago, Little confessed to 90 unsolved homicides between 1970 and 2005.

Along with crimes in Texas and California, Little may also have killed people in Florida, Georgia, Kentucky, Tennessee, Mississippi, Louisiana, Illinois, Ohio, California, Indiana, Arizona, New Mexico and South Carolina, authorities said.

He was previously sentenced in 2014 for the killings of three women — Carol Alford, 41, Audrey Nelson, 35, and Apodaca, 46 — in Los Angeles in the 1980s. DNA linked him to the murders in 2012.

Officials are calling Little one of the most prolific serial killers in U.S. history.
