A police officer in Milwaukee was seriously injured early Sunday after a man walked up to his squad car and fired several shots inside, police said. The officer, a 13-year veteran of the department identified as Brandon Baranowski, was hospitalized with non-life threatening injuries after being hit in his arm and bulletproof vest, NBC News reported. The suspect is believed to have later killed himself. His arrest record includes two prior felonies, police said. He was also the suspect in two domestic violence incidents. The man's uncle told WTMJ the shooting was "not the result of any movement, political agenda, race or gender. It is the result of a young man who was suffering from profound emotional distress." The family expressed in a statement "most heartfelt apologies to Officer Brandon Baranowski and his entire family."
