According to Southern City News, Slacks, who was arrested on Saturday, was in the custody of the state Police Command in Owerri.
When interviewed, the suspect told Southern City News that he was sorry for his actions and was ready to make amends if given the opportunity.
He admitted that he was dismissed from the US military in 2015 over his involvement in cocaine peddling.
He said that he came into the country in February and was ready to refund one of his victims (the widow) her money.
A police source, who spoke on the condition of anonymity, said: “He was a serial fraudster who had used his position as a foreigner to defraud Nigerians, who are desperate to travel abroad, especially to the US.”
The source alleged that the dismissed soldier was in Nigeria on a special mission to defraud Nigerians, adding that he changed his location immediately money was paid to him.
“He is a serial and sophisticated fraudster. He was arrested this afternoon (Saturday) while he was hurriedly leaving Owerri for Port Harcourt.
“He has confessed to the crime and the forensic investigation we have done using his fingerprints revealed that he is a wanted man in California and he only ran to Nigeria in February to continue his heinous crimes.
“Just five days ago, he defrauded a young widow N500,000 with a fake promise that he would secure stay visa for the widow’s three children. He was about running away from Owerri before we tracked him. Could you imagine that the lady we used in tracking him, he had promised to marry her on meeting her for the first time this afternoon (Saturday)”, the source stated.
