Relatives of two women killed when a department store collapsed in a thunderstorm have filed lawsuits charging that the roof was unsafe.

Juan Lopez-Butron of Matamoros, Mexico, whose wife, Graciela Cortinas de Lopez, was the fifth victim pulled from the rubble, filed two lawsuits Monday.Lopez-Butron accused the Amigo Store of failing to warn his wife a collapse could occur and failing to properly inspect the roof and its drainage system.

Luis Enrique Cortinas Villarreal filed a suit seeking damages for the death of his mother, Marisela Villarreal Vda. de Rivera. He named Bernard Levine, owner of the store, and his company, Los Amigos Inc., in the suit, which alleges negligence.

Calls to Levine's home in Brownsville were not answered Monday.
