In her first investigation as Attorney General, Loretta Lynch announced today that the Department of Justice will open an investigation into the Baltimore police department due to a “serious erosion of public trust” following the death of Freddie Gray.

Gray, a 25-year-old black man, died April 19 due to injuries he suffered while in police custody. Six Baltimore police officers have been charged with crimes ranging from unlawful imprisonment to murder in connection with his death. The mayor of Baltimore, Mayor Stephanie Rawlings-Blake, issued a public appeal for the Department of Justice to take an active role in the case.

“Today, the Department of Justice is opening an investigation into whether the Baltimore Police Department has engaged in a pattern or practice of violations of the Constitution or federal law,” Lynch announced at a press conference. She said the investigation will examine whether the department uses “excessive force, including deadly force, conducts unlawful searches, seizures or arrests and engage in discriminatory policing.”

When the Department of Justice completes its report, Lynch said the findings will be released. She added that if “unconstitutional policies or practices are found” they will “seek a court-enforceable agreement to address those issues.”
