HARTFORD, Conn. (AP) The parents of another first-grader killed at Sandy Hook Elementary School in 2012 have filed court documents that could pave the way for a wrongful death lawsuit.

The parents of James Mattioli filed the forms Tuesday in Connecticut probate court, joining parents of 10 other children killed at the Newtown school. The documents seek to establish estates for the children a move required before lawsuits on behalf of the children could be filed.

A court clerk says most of the parents indicated in the documents that they intend to bring wrongful death actions, although the filings don't disclose any potential defendants.

Sunday is the second anniversary of the school shooting in which 20 children and six adults were killed.
