The search for the Wall Street Journal reporter who vanished after leaving his home for a walk in January is resuming in New Jersey.

Michael Mazzeo, the Long Hill Township Police Department chief, told FoxNews.com that crews will be searching Tuesday over ground they covered back in January when David Bird, the reporter, was first reported missing. He said he’s hopeful that the melted snow and ice may yield some clues regarding his disappearance.

"Everything is on the table," Mazzeo said. "There is nothing."

The investigation has been frustrating. All leads have been followed up, but none offered any breakthroughs. Bird, 55, is a liver transplant recipient who takes medication twice a day. His wife Nancy Bird, who has been in contact with police, said he did not have his medication when he left their home and can become ill without it.

The police will be assisted in the search by the New Jersey Search and Rescue Group, along with dogs. They will be searching the path in Hicks Tract Park where Bird has been known to frequent. They have also searched area swamplands and portions of the nearby Passaic River.

Bird, who worked for Dow Jones & Co. for more than 20 years covering OPEC, is described as white, 6 foot, 1 inch tall and weighing approximately 200 pounds. He was last seen wearing a distinct bright red jacket with two yellow zippers.

Anyone with information on Bird's whereabouts is being urged to call The Long Hill Township Police Department at 908-647-1800.
