Veteran investigator shares insights on Boston probe

No one knows more about how bombing investigations are conducted than bomb technicians themselves. Eyewitness News spoke with a 20-year veteran about what investigators in Boston are looking for a day after the horrific explosions.

The investigation into what happened at the Boston Marathon is starting to take shape. The Associated Press is reporting the explosives were in six-liter pressure cookers and placed in black duffel bags.

Sgt. Rich Myers is a bomb tech for the Indiana State Police with 20 years of expertise. He says black duffel bags are not as easy to notice as one would think.

"In today's environment anywhere, a computer case, backpacks are very prevalent throughout the United States and especially at a marathon where people are carrying extra tennis shoes or clothing for when they are done. People waiting on them with drinks and candy bars or Power bars. Very common and unfortunately in today's society that is what we are used to," he said.

Myers says any bomb fragments that are recovered will be valuable to the investigation.

"That is going to be excellent. They will hopefully be able to put them back together, if they were all the same and show this was the same device," he said.

In fact, investigators have already recovered the circuit board believed to have been used in the bombings.

Interviewed at the Indiana Statehouse where he is currently assigned for duty during the ongoing legislative session, Sgt. Myers says the best thing citizens can do is to be observant.

"Be vigilant. If you see something that looks out of place, even if you think that is probably not going to be right. I have probably been to several calls throughout my career as a bomb tech that were not bombs. That is great. That is my job to determine that," he said.

It is being reported that the IEDs (Improvised Explosive Devices) contained shards of metal, nails and ball bearings.

Myers says there is little doubt about why that was done.

"Whenever a fragmentation is added to a device, the only thing it is added to do is to damage property, kill people or maim people. Which unfortunately it did a good job there," he said.

Investigators are still trying to determine what was used to set off the explosives. If it was a cell phone, Myers says that is not hard to build or maintain.

In another investigation note, police and federal agents renewed appeals today for any video, audio and photos taken by marathon spectators.
