The sixth prosecution witness in the trial of John and Yvette Nikolic says that John Nikolic had told him that he owed some dangerous people money and this was his only way out.

Customs Officer Fenton Williams says John had also told him that his wife and the other crew members did not know about the drugs. 

Williams confirmed that John was escorted to another crew member, Jeffery Hassle's cabin to use the washroom.

He then said that after visiting the washroom John had collapsed because of a drug overdose while talking to his wife.

John and Yvette Nikolic are jointly charged with two counts of possession of illicit drugs, one count of possession of arms and ammunition without a licence and two counts of unlawful importation of illicit drugs.

It is alleged that the couple had imported 12.9 kilograms of cocaine and 34.4 grams of methamphetamine with an estimated value of between $20 million to $30 million.

It is also alleged that they failed to declare that they had in their possession two pistols with 112 rounds of live ammunition.
