A big-hearted Revere firefighter who left his wallet to dry on a firehouse window ledge after battling a blaze said yesterday he pities the career criminal accused of stealing it — but he’s more concerned about the two tykes she had in tow. “I feel sorry for her and for the kids she was with, too,” Jamie Nadworny told the Herald. “I’m glad they have her if she has a rap sheet. Hopefully she’ll get whatever help she needs. And I feel really bad for the kids. I hope they don’t follow in her footsteps.”
