A man who allegedly trafficked “ghost guns” and silencers he assembled at his Philadelphia-area home has been charged along with two friends, authorities said Wednesday.

Tony Phan Ho, 32, and Ritha “Kay” Ngoy, 36, both of Hatfield, and Michael Phan Nguyen, 32, of Lansdale, were all charged with operating a corrupt organization, conspiracy and weapons counts, Montgomery County District Attorney Kevin Steele said.

Federal investigators began tracking Ho in May, when they learned a shipment of silencer components had been sent to his home, according to court documents. Montgomery County detectives and federal authorities intercepted the package and interviewed Ho.
