Victims' Families Ask: Why?

Though Mark Barton, the gunman who shot up two brokerage offices in Atlanta, vowed in a note to kill the people who "greedily sought my destruction," most of his victims had little or nothing to do with him.

In Norcross, Georgia, CBS News Correspondent Randall Pinkston reports Scott and Mike Quinn are coming to terms with the sudden, brutal murder of their father. Scott says his dad Edward "was the nicest, kindest man ever. He would do anything for anyone."

Day trading was a new hobby for Quinn, who had just retired from U.P.S. and recently became a grandfather. Scott and Mike say he went to Momentum Securities - where he met Barton - three days a week for a few hours.

"My father was the type of person who became friends with everybody, he was a very warm individual, likeable personality," Mike says.

Day Trading: A Risky Business


Both sons are mystified about why their father was shot. So is Rishi Muralidhara, who is trying to cope with the death of his mother, Vadewattee Muralidhara.
Muralidhara explains, "When I come back for holidays, she's not going to be there, and just because some stupid mad guy wanted some revenge on some innocent people."

His family had moved into a new home six months ago; Rishi said his mom saw day trading as a way to make extra money to pay the bills, and she'd just begun training for the task two weeks ago.

"She was a good mom," he says. "I wasn't always the obedient son, I mean I had my share of troubles at school. Whatever I did, she always stood by me."

The victims of Mark Barton once shared a hobby. Now, clinging to memories, their families share a grief.
