(Indianapolis, IN) -Another execution has been scheduled at Indiana State Prison.

Benjamin Ritchie was convicted of killing a police officer downstate over 20 years ago.  According to authorities, Ritchie was being chased in a stolen van then later on foot when he turned toward the officer and fatally shot him four times.

The execution at the Michigan City prison is set for May 20. The date was set by the Indiana Supreme Court at the request of the Indiana Attorney General’s Office.

If it goes through, this will be the second execution in Indiana since December when the first prison offender in 15 years was put to death in the state.

Until then, a hold had been placed on executions because of a long term shortage of lethal injection drugs.
