President Barack Obama signs the American Recovery and Reinvestment Act into law.

The act includes $2 billion for a program called the Justice Assistance Grant [JAG], meant to bolster state, local and tribal police departments.

Allegheny County enters into a grant agreement with 34 municipalities to distribute $3.2 million of the grant.

In that agreement, Pittsburgh proposes spending $675,000 of its share on projects later commissioned from Plum-based contractor B-Three Solutions Inc. The city has until Feb. 28, 2013, to complete and implement the projects, according to Department of Justice rules.

The city has been working with B-Three on six grant-funded projects. This month, the company submitted its last statements of work that outline the projects that will be paid for with grant money, some of which had initially been proposed in 2008 and 2009.

Pittsburgh police officials sign a memorandum, asking the Department of Justice for an extension on the grant to finish several of B-Three’s projects. That request is later denied.

The grant period for the stimulus grant ends.

Pittsburgh pays B-Three $178,500 for remaining work on grant projects despite the grant period having ended. Pittsburgh was reimbursed with federal money before the close of the grant period. The city paid B-Three more than $447,000 for its projects during the grant period.

County officials send $156,147 back to the Department of Justice, $153,102 of which is money “unspent” by Pittsburgh.

Available documents do not specify if the money is related to specific projects.

Cameron McLay is hired as Pittsburgh’s chief of police.

McLay, having suspicions about the bureau’s reliance on B-Three, orders a freeze on payments to the company.

McLay also notifies the FBI.

McLay and his chief of staff lodge a complaint with the city's Office of Municipal Investigations.

The complaint alleges that Linda Rosato-Barone, now Deputy Director of Public Safety, and Sgt. Anthony Cortopassi, a now-retired officer who worked on technology projects, knowingly contracted with B-Three for "subpar" software and violated provisions of a federal grant.

McLay announces his resignation.

The city’s Office of Municipal Investigations concludes in a report that there was no wrongdoing by Rosato-Barone or Cortopassi regarding the police bureau’s work with B-Three.

However, the report found numerous problems with police technology projects.

Police officer Souroth Chatterji files a federal whistleblower lawsuit alleging he was retaliated against by Rosato-Barone and others under her supervision for raising concerns about the 2009 grant and the bureau’s relationship with B-Three.

The city and Rosato-Barone respond in court to the allegations in the whistleblower lawsuit. In addition to requesting that the case be dismissed, they argue that Chatterji's claims are false.
