There is now an email account for tips in a number of unsolved murders from the 1980's in Virginia.
The slayings are known as the Colonial Parkway murders. Two women whose throats were slit were found off the parkway in 1986, and two couples were later found dead in the area.
Another couple disappeared. The FBI announced in October it will use DNA and other new techniques to search for clues.
Now it has set up the email account so that anyone with information about the killings and the disappearance can provide information for the investigation.
FBI agents met with families of the victims on Friday.
