Initially, she was believed to have drowned accidentally. Seven months after her forensic results were released, and they revealed that she was murdered as someone pushed her head underwater until she drowned. Various publications gave insights as to what would have happened with her. A source stated that Sobhraj knew that Teresa would check-in to Hotel Malaysia and sent his accomplice Ajay to somehow bring her to his apartment. Another source claimed that she was drugged when refreshments were served to her, and she was stripped and a bikini was put on her. One other source stated that Teresa went out for drinks at a bar with Sobhraj and Ajay and was drugged. Teresa was then put in Sobhraj and Ajay’s car and taken to Pattaya Beach. Sobhraj then commanded Ajay to take her to swim, and in the process, drowning her. It is still unclear as to what caused Sobhraj to murder her, but according to the Dutch diplomat Herman Knippenberg, Sobhraj killed her because she refused to join his team and become a smuggler. Later, Sobhraj confessed to murdering her in many interviews, saying,

The girl from California. She was drunk, and Ajay brought her to Kanit House. We knew about her, you see. We knew she was involved with heroin. I killed her because she was transporting drugs.”
