DETROIT, MI -- Timothy Cromer, a former Detroit Public Library official who was fired in February 2013 and accused three months later of accepting kickbacks from technology contractors, was sentenced Tuesday to 10 years in federal prison, according to the U.S. Attorney's office.

Cromer, 47, of West Bloomfield, was the library's chief administrative and technology officer between 2006 and 2013.

He was paid a salary of $145,323 a year, according to the FBI, which raided the library for financial records in November 2012.

Investigators accused him of accepting $1.4 million in kickbacks from two contractors.

Prosecutors alleged Cromer helped co-defendant James Henley create Core Consulting & Professional Services in 2007, then awarded the company $1.8 million in information technology work for the library.

He was also charged with approving $2.8 million in no-bid contracts to Cubemation, LLC and taking kickbacks from its owner Ricardo Hearn.

Cromer pleaded guilty to bribery charges in April.

Henley and Hearn each previously pleaded guilty to conspiracy to commit bribery and are scheduled to be sentenced Oct. 28, according to the U.S. Attorney's office.

"Our public libraries exist to enrich our citizens, not to generate profits for the officials who work there," said United States Attorney Barbara McQuade said in a statement.

"Today's sentence protects the important interests of taxpayers, library patrons and the honest public servants who have dedicated themselves to the Detroit Public Library."
