Former two-year college chancellor Roy Johnson made good on his deal to plead guilty to 15 counts of corruption Monday, bringing the scandal he started closer to its end.

U.S. District Judge Karon Bowdre is to sentence him in August, which gives him more opportunities to earn less than a lifetime in prison if he continues to cooperate with federal authorities. He is 62.

In addition, he’s agreed to repay more than $18 million, which federal officials say was the amount he and others siphoned from the two-year college system.

U.S. Attorney Alice Martin, whose office continues to prosecute the scandal, said Mr. Johnson acted out of greed and not from need.

People who are in position to steal large amounts of money are rarely in need. Instead, those who steal as Mr. Johnson did, succumb to greed and power.
