She may not have been killed right away or even for a while after she disappeared. She might have been abducted. It's possible that she got involved with some dangerous people doing illicit things and they decided to take her along with them rather than risk her talking.
She clearly went to meet someone, to do something before work. I think that's where it went bad. She did not want to come along with these people, so they forced her.
