Big Dig 'Whistleblower'

When state and federal authorities detailed their Big Dig settlement this week, there was one funding line for what they called "whistleblower." That's Daniel Johnston. He'll receive $150,000 as part of the $458 million agreement with Bechtel and other contractors.

Johnston was a quality-control technician for Aggregate Concrete and worked on the Central Artery Project from mid-1997 to late 2001. He came forward with information about the Big Dig before the collapse of tunnel ceiling panels that killed Milena del Valle in 2006.

One of the lawyers representing Johnston, Suzanne Durrell, joins WBUR's Bob Oakes this morning to talk about Johnston's involvement in the investigation and the settlement.

Audio for this story will be available on WBUR's web site later today.
