Criminal profiler speaks on Catherine Greig

BOSTON -- Why did Catherine Greig follow Whitey Bulger for so long, and what's next for her? 7NEWS spoke with an expert in the criminal justice field who gave us her take.

Just Monday, the FBI released a new public service announcement targeting Catherine Greig's whereabouts.

The reward for her capture doubled and a tip from a viewer who heard about the PSA led to Bulger and Greig's capture.

But will Greig fold when she's questioned about her fugitive boyfriend?

Here's what a nationally recognized criminal profiler thinks:

“I wouldn't be surprised if she’d give up some information; of course she does have to worry about some repercussions out there, but either it’s the repercussions that she gets out and somebody doesn’t like her or getting her in prison, or she’s going to spend the rest of her life there anyway,” said Pat Brown.

Greig is some twenty years younger than Bulger.

“She's really got nothing to lose at this point and she doesn't want to spend the rest of her life in prison. This is not something she’s used to, and she’s young enough - she’s 60 so she probably doesn’t think this is a great idea,” said Brown.

Greig faces charges of harboring a fugitive. She fled with Bulger 16 years ago, but was true love the reason they've stayed together on the run for so long?

“His girlfriend wasn't somebody he loved. His girlfriend was somebody he used,” said Brown. “We find there are a lot of women that like being with the bad boy, that's why we have women marry serial killers in prison and they killed 20 people but they still married them. They love the celebrity because without that hookup they're just a plain old person,” said Brown. “Who wants to be just a plain old person?”

If Greig is eventually convicted of harboring a fugitive, she faces up to five years in prison.

But federal officials say they may pursue more charges against her.
