Leonard received 18 years in prison, while Huynh Ha Binh, Huynh Ha Uyen and Nguyen Tran Quynh Nhi, all from Ho Chi Minh City, got between 12 to 15 years each.
According to the indictment, Leonard and Binh, 27, started living together in August 2014 in Ho Chi Minh City before moving to Cambodia and opening a fashion shop.
While in Cambodia, the duo hatched a plan to con rich Vietnamese women via the social media. Facebook’s Messenger and Zalo are the two most popular chat apps in Vietnam.

The Nigerian man used fake accounts and described himself as a rich man or even a U.S. Army officer who had just gone through a divorce and was “lonely.”
He approached wealthy women and tried to build a relationship with them, and as many as 37 fell for the trick.
To gain their trust, Leonard told the women he would send them valuable gifts such as laptops, cellphones, jewellery and cosmetics from the US.
When the women were sucked in, Binh, Uyen and Nhi pretended to be Vietnamese customs officers and contacted the women, telling them that packages sent to them contained expensive goods or large amounts of foreign currency, so the women would have to pay a customs fee or even a fine.
In late March 2016, after the group had conned a woman in Can Tho City out of VND650 million ($28,500), Leonard and the other three were arrested.
They all confessed to their crimes in court. Binh and Leonard have a child together, and the baby is now with Binh’s parents.
