Robinault, who went by the name "Alexis Sharkey" on Instagram, shared photos from his travels in Texas and beyond with his followers.
Her mother, Stacey, told CNN affiliate KTRK that she had not spoken to her daughter since Thanksgiving, days before her body was found.
Alexis Sharkey "traveled as much as he could" and dreamed of seeing the world, his mother said.
Despite her modest number of followers online, she was always herself.
"To her integrity, it was obvious that what she had out there was what she was and what she believed in," Stacey Robinault told KTRK.
When contacted for comment, the Houston Police Department directed CNN to its Twitter page, where police indicated they will share updates on the case.
