"James Bulger and Catherine could be anywhere in the world, and we're always looking for opportunities to find them," Special Agent Gail Marcinkiewicz from the Boston Branch of the FBI told ABC News.
"The more people who see the pictures, the more opportunities we have to find them. We've never tried this through Plastic Surgery News, but this may be a very positive thing to do," Marcinkiewicz said.
Bulger is wanted by the FBI for allegedly committing 19 murders, as well as charges of extortion and drugs during his alleged reign as the leader of a Boston organized crime syndicate in the 1970's and 1980's.
"Some of the challenges to catching Mr. Bulger is that although he is in his 80's, he's traveling with a woman 21-years younger. He's been a fugitive for 15-years, and he looks like many people his age and probably stays under the radar," Marcinkiewicz said.
Bulger, who has previously spent time in Alcatraz prison for bank robbery, told law enforcement before he went on the run that he would never go back to jail. Marcinkiewicz said the FBI feels he most likely planned his fugitive years well, including seeding money across the world.
"He spent many years planning to be a fugitive," she said.
The FBI has had many reported sightings of Bulger throughout the years, however the agency says the last corroborated sighting of Bulger and Greig came in 2002 in London. Currently there is a $2 million reward offered for helping to bring them in. Despite their ages, both are considered dangerous.
"We've always known him to carry a knife and we can only assume that he exhibits some of his past behavior. He's a very engaging guy, with a very violent temper," Marcinkiewicz said.
Sevinor thinks that despite perhaps needing or recently receiving new implants, Greig's past surgeries may entice her to go under the knife once again as she reaches her 60's.
"This is a woman who had four surgery procedures from 1982 to 1992, and the likelihood is that at 59-years-old she may have even more procedures," Sevinor said.
"Is it possible to find her through a surgeon? I think it's possible," he said.
A sentiment the FBI most likely shares.
"We would very much like Mr. Bulger to be found, and brought back to justice," Marcinkiewicz said.
