New Haven, Connecticut-based attorney Irving Pinsky said he dropped the claim because he was evaluating new evidence, according to a report on CTPost.com.
Pinsky said he did not rule out further legal action, the report said. He did not respond immediately to Reuters requests to comment on the report.
The attorney filed the claim last week on behalf of an unidentified 6-year-old survivor of the Newtown shooting at a primary school that left 20 children and six adults dead on Dec. 14.
The survivor, referred to as Jill Doe, “has sustained emotional and psychological trauma and injury, the nature and extent of which are yet to be determined,” the claim said.
State Attorney General George Jepsen on Monday called the claim misguided and said a public policy response by the U.S. Congress and the Connecticut state legislature would be more appropriate than legal action, according to a spokeswoman.
