WASHINGTON — The Justice Department plans a wide-ranging civil rights investigation into the practices of the Ferguson, Missouri, police department following the shooting last month of an unarmed black 18-year-old by a white police officer in the St. Louis suburb, a person briefed on the matter said.
Attorney General Eric Holder was expected to announce the investigation Thursday afternoon at a Justice Department news conference.
The investigation will look at the practices in the past few years of the police department, including patterns of stops, arrests and use of force, as well as the training the officers receive, said the person, who was not authorized to discuss the announcement publicly until it was made and spoke on condition of anonymity.
The new inquiry is separate from an ongoing civil rights investigation the Justice Department is conducting into the shooting of 18-year-old Michael Brown by Officer Darren Wilson on Aug. 9. A local grand jury is also investigating the shooting, which set off about two weeks of unrest in the streets of Ferguson and became a flashpoint in the national discussion of police treatment of minorities across the country.
Attorney General Eric Holder two weeks ago visited the St. Louis suburb, where he met with investigators and Brown’s parents and shared personal experiences of having himself been mistreated by the police.
Ferguson Police Chief Tom Jackson did not return phone calls seeking comment about the Justice Department investigation.
Police have said the shooting followed a scuffle that broke out after Wilson told Brown and a friend to move out of the street and onto a sidewalk. Police say Wilson was pushed into his squad car and physically assaulted. Some witnesses have reported seeing Brown’s arms up in the air before the shooting in an act of surrender. An autopsy paid for by Brown’s family concluded that he was shot six times, twice in the head.
The new investigation, though, will go well beyond the circumstances of the shooting. It will look at the actions of a police department that is predominantly white even though Ferguson is about 70 percent black.
Some in Ferguson have said police disproportionately target black motorists during traffic stops. A 2013 report by the Missouri attorney general’s office found that Ferguson police stopped and arrested black drivers nearly twice as frequently as white motorists but were also less likely to find contraband among the black drivers.
The Justice Department’s civil rights division routinely investigates individual police departments when there are allegations of systemic use-of-force violations, racial bias or other problems. The department says it’s opened 20 investigations in the past five years, more than twice the number opened in the previous five years.
The investigations typically encourage significant changes to policies and practices and often end with settlements — known as consent decrees — in which the department agrees to make specified reforms.
The Justice Department reached a court-supervised agreement in 2012 with the New Orleans police department that would require the agency to overhaul its policies and procedures for use of force, training, interrogations, searches and arrests, recruitment and supervision.
In April, it issued a harshly critical report of the Albuquerque, New Mexico, police department that faulted the agency for a pattern of excessive force and called for an overhaul of its internal affairs unit. The city and the Justice Department have been locked in negotiations over ordered changes.
