Crystal Ana Lopez, 34, of San Antonio was last seen on April 27, 2017, near her apartment complex in the 17000 block of Henderson Pass. That morning she dropped her son at school and, according to her boyfriend, went to walk her white Maltese dog Giana and never returned. Both Crystal and Giana have been missing since.

Several personal items were left behind at the apartment: Giana’s collar and leash and Crystal’s dentures, which she reportedly never left home without. Her car was found parked haphazardly on the complex grounds. Crystal had a medical condition requiring regular medication. Authorities have not ruled out foul play, and no substantial leads have emerged.

Anyone who knew Crystal, saw her or her dog on April 27, 2017, or has information that could help investigators is asked to contact the San Antonio Police Department.
