A federal judge on Monday chose a monitor team to oversee reforms of Ferguson's policing and court system, a process expected to cost the St. Louis suburb more than $1 million.

U.S. District Judge Catherine Perry announced that Squire Patton Boggs, a law firm based in Cleveland, was picked from four finalists to make sure reforms are adequate in Ferguson. City officials say the cost of the monitoring will not exceed $1.25 million over five years, or $350,000 for any single year.

The team will be led by Clark Ervin, who was inspector general for the U.S. State Department and Homeland Security before becoming a partner at Squire Patton Boggs.

A consent decree between the city and the U.S. Department of Justice, approved by Perry in April, calls for diversity training for police, outfitting officers and jail workers with body cameras, and other reforms.

"I'm excited that both the City of Ferguson and the Department of Justice have worked together to complete the process of choosing an Independent Monitor," Ferguson City Manager De'Carlon Seewood said in a statement. "This is a true testament that the collaboration between both parties had a mission and that is to do what's best for the Ferguson community and its police department."
