The Nu Epsilon chapter of the Omega Psi Phi fraternity at Alabama A&M University started a online petition Thursday demanding federal as well as state authorities to take over the investigation from the Bloomington Police Department into the death of 25-year-old Jelani Day. "This agency has shown the inability to handle a case of this nature," the fraternity said in a letter to state and federal officials included with the petition. "Jelani is loved and represents the absolute best of our beloved fraternity; therefore, bringing those responsible for this heinous act to justice is not a request but a demand," the letter said. "The person(s) responsible for Jelani's death is now walking our community free, and we will not rest until those responsible are brought to justice." The petition and letter were also shared by Day's mother, Carmen Bolden Day, on her Facebook page. Ill.
