TAMPA, FL (WFLA) -

Family members of a woman killed in September's Navy Yard shooting in Washington D.C. are hoping a lawsuit will prompt change.

Sidney Matthew filed the lawsuit in Tampa Federal Court on behalf of Patricia Delorenzo. Delorenzo's sister, Mary Frances Delorenzo Knight was one of a dozen victims in the mass shooting.

The suit names the United States Department of the Navy, the Department of Veterans Affairs and two government subcontractors; The Experts, L.L.C. And Hewlett Packard Enterprise Services. The suit alleges the defendants knew or should have known that Aaron Alexis, the shooter, was potentially dangerous before he entered the Navy Yard with a sawed-off shotgun in September.

"On August seventh, when Alexis showed his true colors, that he was a real rattlesnake and homicidal, what they should have done is revoke his security clearance. That was actually done. That was actually done," said Matthew.  "The problem is, the experts restored his security clearance two days later. "

The suit seeks monetary damages, but Patricia Delorenzo says she hopes it prompts change to prevent future massacres. She believes metal detectors should be installed at all federal installations.

"The metal detectors would be great," said Delorenzo.

"And, changes in the security clearance to make sure that the security clearances are a little bit more tight. Like allowing someone like this to keep his clearance. "

William Daniels, a spokesman for the U.S. Attorney's Office, said he could not comment on the case because it is pending litigation.
