The mystery of the fate of International Brotherhood of Teamsters boss Jimmy Hoffa is one of the most enduring in American history. Hoffa vanished in July 1975 and in the decades since his name has become a punchline for jokes about unexplained disappearances.

Shouts and murmurs of a new Hoffa resting place come out every other year or so--the latest candidate is an innocuous suburban driveway in Roseville, Michigan. It's hard to take new rumors that Hoffa's grave has been found too seriously anymore, but ABC News reports there may be something to this one:

James Berlin, the police chief in Roseville, Mich., a town about 20 miles north of Detroit, says his department will take soil core samples from under the driveway of a home in the area this Friday after "credible" information recently surfaced.

"We received information from an individual who saw something," Berlin told the Detroit Free Press. "The information seemed credible, so we decided to follow up on it."

Multiple Michigan press outlets say Michigan's Department of Environmental Quality recently performed a "ground scan" of the driveway and discovered evidence that something is buried beneath the pavement.

Detroit TV station WDIV reports that the tip regarding Hoffa's location was credible because it came from a witness who is dying of cancer. Roseville's police chief told the NBC affiliate that the dying man "believes what he saw. That something took place that day out of the ordinary."

The same broadcast outlet also notes that the FBI is skeptical of the story, one retired agent telling WDIV that the claim "doesn't match up with anything we already know. I'd say it's just another story. Someone is trying to get publicity or is looking after a reward."

This new claim may at least present another opportunity for late-night talk hosts to open a forgotten desk drawer and blow dust off a fading folder labeled, "Jimmy Hoffa jokes."

The unsolved 2004 murder of Juilliard acting student Sarah Fox is going from cold to hot--and new evidence in the case has been tangentially linked to Occupy Wall Street. NBC 4 reports police have connected DNA found at the Inwood Hill Park murder scene to DNA collected from a chain found at the scene of an Occupy Wall Street protest in East Flatbush late last March. The evidence is direct; the genetic evidence was obtained from Fox's pink CD player, found near her nude and strangled corpse in May, 2004:

Sources said Tuesday the DNA found on the CD player is linked to DNA found on a chain left by Occupy Wall Street protesters at the Beverly Road subway station in East Flatbush on March 28, 2012.

That Wednesday morning, protesters chained open emergency gates and taped up turnstiles in eight subway stations and posted fliers encouraging riders to enter for free.

The protest was a response to this action posted by something called the Rank and File Initiative. The communique called the action #farestrike and stated that on the morning of March 28 "teams of activists, many from Occupy Wall Street, in conjunction with rank and file workers from the Transport Workers Union Local 100 and the Amalgamated Transit Union, opened up more than 20 stations across the city for free entry."

The NBC affiliate's sources say the DNA has yet to lead to a suspect.

Police have long regarded  Dimitry Sheinman as a person of interest but Mr. Sheinman has never been charged.

Sarah Fox's murder was strange in many respects. She wasn't found for six days after she disappeared on a run. According to America's Most Wanted, yellow tulip tree petals were arranged in a circle around her remains.
