It's a case that's been cold for nearly 40 years — Bernard "Bunny" Ross Jr. disappeared back in 1977.
But an anonymous letter sent to Ross' parents in Portland, Maine, claims to know where he is.
Maine State Police told the Portland Press Herald his parents received the letter "a few months ago" but didn't go into more detail. Police are asking whoever wrote the letter to come forward.

Foreboding Kingsbury Run, shunned by the timid as the legend of its murders has grown, is indicated on this map by dots locating 10 of the 11 torso murders which have occurred there since Sept. 23, 1935. Police, delving into the lives of the mad murderer's victims, hope to uncover clues which will end the periodic killings. Discovery of photo negatives in the belongings of Edward Andra Ssy, first victim, show Andra Ssy in a strange room which, if identified, may provide a live lead, police believe. As the map shows, the murderer departed only twice from his custom of assailing victims in Kingsbury Run or adjacent Cuyahoga river valley.

U.S. labor leader Jimmy Hoffa is photographed at the Greater Pittsburgh Airport, Pennsylvania in this April 12, 1971 file photograph. Hoffa was switching planes from San Francisco, and was returning to the federal prison in Allenwood, Pennsylvania. Hoffa was let out of prison to visit his wife, who had been hospitalized with heart problems. FBI teams on May 25, 2006 sifted by hand through dirt from a chest-deep hole in the ground in an intense search for the body of Jimmy Hoffa three decades after his disappearance. Hoffa was last seen outside a Detroit-area restaurant where he was to meet New Jersey Teamsters' boss Anthony "Tony Pro" Provenzano, a member of the Genovese crime family, and a local Mafia captain, Anthony "Tony Jack" Giacalone. Hoffa was declared dead in 1982, and numerous books about his life have pinned his disappearance on mobsters who murdered him because they did not want him interfering with their close ties to the union.
