The parents of a woman who died after falling out a 10th floor hotel window have filed separate lawsuits that claim the W Atlanta-Midtown knew the glass was defective and improperly installed.

LaShawna Marleece Threatt's father, MauriceThreatt , filed a suit in Fulton State Court on behalf of his daughter's estate. Sharon Traylor, the dead woman's mother, also filed a complaint in Fulton State Court on Friday on behalf of her granddaughter, LaShawan Threatt's daughter.

Maurice Threatt's complaint said the glass in a window in room 1012, where LaShawna Threatt and her friends had gathered May 28 to celebrate her 30th birthday, had recently been replaced and it was "not properly tempered for use as an outside wall window."

Witnesses said LaShawn Threatt and a friend, Cierra Williams, were horseplaying near the window when the glass shattered and the two fell out. Both first landed onto a slanted sunroof adjoining the hotel.  LaShawn Threatt stayed on the sunroof but Williams rolled off and onto the ground. Williams was critically injured.

The hotel management, in statements to the media, has declined to comment on the suit but said reports from inspections of the property "when when it became a part of the W brand in 2008″ did not raise any concerns "about the safety or security of its windows or window system structure."

Both suits ask for unspecified damages to be determined by a jury.
