List of GOP lawmakers found in Virginia shooter's pocket

Investigators have not determined the purpose of the list.

— -- A list of Republican members of Congress was found in the pocket of James T. Hodgkinson, who was killed Wednesday after allegedly firing on Republican lawmakers practicing for a charity baseball event, sources told ABC News.

The list contained about a dozen names, a source said. Investigators have not determined the purpose of the list and they are still trying to determine its meaning.

Sue Hodgkinson, the accused gunman's wife, told reporters Thursday she was shocked by her husband's actions, saying, "I can’t believe he did this."

She said she was married to James Hodgkinson for nearly 30 years but they have not been together since March, when he moved to Washington, D.C.

Sue Hodgkinson said she felt "horrible," saying, "I had no idea this was going to happen and I don't know what to say about it. I can't wrap my head around it.

"I'm sorry that he did this," she added. "There's nothing I could do about it."
