$10,000 reward offered for information leading to capture of suspected killer who was accidentally released from Indianapolis jail

The US Marshals Service is offering $10,000 for those who come forward with information leading to the arrest of a suspect in a 2021 killing who was released from a detention center in Indianapolis last week due to a clerical mistake, officials said.

Kevin Mason, 28, was "mistakenly released" from an adult detention center in Marion County on September 13, two days after his arrest, "due to a faulty records review" by staff, according to the Marion County Sheriff's Office. A manhunt for Mason is underway, and the sheriff's office is asking for the public's help finding him.

It's unclear whether he's still in the county, sheriff's Col. James Martin said in a news conference Tuesday.

Mason was arrested in Indiana on September 11, having been sought on three Minnesota warrants, including one asking he be held on suspicion of murder in connection with a 2021 shooting in Minneapolis, the sheriff's office said. The other warrants relate to an alleged parole violation and firearms possession, Martin said.

He was released after a Marion County sheriff's clerk thought she was correcting duplicate bookings for the inmate and removed two holds in his file, Martin said. The next day, a clerk in Minnesota lifted the final hold in Mason's file and did not catch the error that happened the day before, according to the colonel.

Two inmate records clerks involved in Martin's release have been fired, and an internal investigation is being conducted, according to Martin.

"This was an error - this should not have happened. Mason should not have been released from our custody," Martin said.
