Police said Saturday they weren’t discarding the possibility that human trafficking played a role in the disappearance of a former Miss Brazil who hasn’t contacted her family since September.

Taiza Thomsen, 24, represented Brazil at the 2003 Miss Universe pageant in Panama. The last time she spoke to her parents, she said she was in London.

“At this moment we can’t rule out anything, not even the possibility she was a victim of human trafficking,” police investigator Marcos David Salem told Brazilian TV.

Police began investigating the case Friday, after Thomsen’s family reported her missing the previous day. Police said they had no leads.
