Alejandra Gueldner, 63, was found badly beaten and sexually assaulted on January 17, 2014, around 4:45 a.m., lying outside a business at 1200 Hardy, just northeast of downtown Houston. Surveillance shows her leaving the Hilton Americas after her shift and later walking near the George R. Brown Convention Center before she disappeared from view.

She was taken to a hospital and died of her injuries on January 22.

If anyone was in the downtown Houston area that early morning or saw Alejandra after she left the hotel, please come forward with information.
