MEMPHIS, Tenn. (AP) -- Two more people face charges of participating in a scam where stand-ins were hired to take teacher licensing exams.

Federal prosecutors in Memphis on Thursday announced charges against 28-year-old Clarence Mumford Jr., of Memphis. He is accused of paying someone else to take his exam and then using that exam to obtain a teaching license.

Forty-year-old Dante Dowers, of Belle Glade, Fla., is accused as acting as a middle man who obtained a prospective teacher's driver's license, Social Security number and $3,580 payment for an exam that someone else took.

Prosecutors claim that Mumford's father, 58-year-old Clarence Mumford Sr., was the ringleader of the scam, which involved teachers in Tennessee, Arkansas and Mississippi. He was indicted last month on fraud and identity theft charges.
