WILMINGTON, Del. (AP)- A New Jersey man who bribed an administrator at Delaware State University to get in-state tuition rates for hundreds of out-of-state students has been sentenced to more than three years in prison.

Stephen Williams of Neptune, New Jersey is an alumnuns of the historically black university. He pleaded guilty last year to bribery charges in federal court in Wilimigton, Delaware, where he was sentenced Friday to 42 months in prison.

Authorirties say the school lost out on more than $3 million in tuition payments from more than 250 students in a scheme that ran from 2013 through 2017.

Prosecutors say they still do not know how much money Williams made in the scheme.

Former DSU associate registrar Crystal Martin, who accepted the bribes, will be sentenced next month.

Under the scheme, Williams collected a fee from the students who sought to pay in-state tuition, and Williams paid a percentage of that fee to Martin as a bribe.
