A massive manhunt is underway in Indiana after detention center employees accidentally released a murder suspect and kept the debacle under wraps for six days for a "tactical advantage" in finding him. 

Marion County Sheriff's Office said in a press release that 28-year-old Kevin Mason was mistakenly released from the Adult Detention Center (ADC) on September 13, two days after his arrest, "due to a faulty record review" by staff.
