When the owner returned back to the ground floor, Mathis said she was so thankful but still visibly upset and couldn't stop crying."I think she just said 'thank you' and we hugged but she was just so overcome with emotion," he said.Mathis hasn't seen her since but thinks she had just moved to the apartment complex so he wasn't sure if she didn't know how the elevators worked, but that there was really no way to know that this could have happened the way it did.A day after the incident, Mathis went to his apartment leasing office and explained to the leasing agents what happened. They went to take a look at the security video and saw it unfold all over again in disbelief that the dog made it out safely.Mathis was happy he was there to help and said this could have happened to anyone -- a perfect example of being in the right place at the right time.
