Police are not convinced by statements given by five people on the speedboat with TV actress Nida "Tangmo" Patcharaveerapong when she fell overboard to her death, Pol Lt Gen Jirapat Phumjit, head of Provincial Police Region 1, said on Tuesday.
"The cause of death is found [at this point] to be drowning. To determine what actually caused her to fall into the river, whether it was herself or someone else, will take time.
