Taylor's car was found abandoned in Houston's Midtown on Tuesday.
Equusearch spent days searching Bear Creek Park, one of the last places Taylor's phone may have pinged. They found nothing and called off their search Thursday.
Gibson's father Josh Gibson says it's unlike her to not stay in contact with him. He says he doesn't have any indication anything bad has happened to Gibson, but he is still worried. She is a single mom and her parents are now caring for her young son.
Taylor's mother believes her son, a father of four, is still alive.
Family members are offering a $5,000 reward for information that can help find them.
Anyone with information about their disappearance should contact police or Equusearch at 877-270-9500.
