ANNAPOLIS, Md. — Gov. Martin O’Malley says his administration will introduce bills aimed at preventing catastrophic mass shootings like the one that happened last week at an elementary school in Connecticut.

O’Malley told reporters Tuesday that the details of the legislation have yet to be worked out, but that he believes everyone has been changed by Friday’s massacre at Sandy Hook Elementary School in Newtown, Conn. The gunman, Adam Lanza, killed his mother and then shot 26 children and school staff members before killing himself.

O’Malley says the shooting prompts questions about laws relating to assault weapons, mental health and school safety.

O’Malley made the remarks during a discussion of the state’s progress.

Meanwhile, Sen. Brian Frosh said he and other lawmakers plan to announce this week a package of gun control legislation.
