Two WA men guilty of drug charges

Two Perth men have been found guilty of possessing and selling several kilograms of hard drugs.

Marc Quaid and Roberto Zanon were convicted by a jury on Tuesday in the Perth District Court of one count each of selling and supplying methylamphetamine.

Quaid was also found guilty of another count of the same charge over a separate haul of methylamphetamine, but was acquitted of one count of possessing heroin with intent to sell or supply.

Family members sobbed in court when the verdict was handed down.

Prosecutors had alleged during the trial that a witness, whose identity was suppressed, had implicated Quaid and Zanon in the drug dealing operation after the narcotics were discovered by police in March last year.

The witness had provided general descriptions of the men, selected their images from a photo board, described the cars they drove, gave an approximate description of where they lived and supplied other information.

A search of Quaid's home uncovered $231,690 in cash and a canister that contained a plastic bag with a crystalline residue inside that was found to be a cutting agent, the trial heard.

The witness told police the codename "World 150" was used for Quaid, while he believed Quaid's driver was named Adrian Zanich.

Both men were remanded in custody and will be sentenced later this month.
