The father of a Chinese-Canadian woman whose body was discovered in a hotel's rooftop water tank in downtown Los Angeles said he is unsatisfied with the autopsy conclusion that his daughter accidentally drowned, Canadian media reported.

Lam’s father said that he is planning a trip to L.A. to get more information himself, according to the report.

The L.A. coroner's office recently said they found neither external scars on 21-year-old Elisa Lam's body nor poison or drugs in her system that could have resulted in her death. The coroners concluded her death was accidental. They also noted that Lam suffered from bipolar disorder.

“How did she climb up (to the rooftop tower) and how did she die? These questions remain unclear,” said Lam’s father to the newspaper Sing Tao Daily. He also said his daughter was alert and quiet that she was not bipolar.

Elisa Lam traveled to Los Angeles on January 26 and stayed at the Cecil Hotel. She last spoke with her family on January 31.

A maintenance worker found Lam's corpse in the water tank on February 19 after hotel guests complained of low water pressure.
