On May 8, 1986, a tragic event unfolded in Greenfield, Indiana, leading to the death of a dedicated law enforcement officer. Captain Malcolm Grass, a 43-year-old male and a 14-year veteran of the Hancock County Sheriff's Office, was fatally shot while assisting the Federal Bureau of Investigation in an extortion case. The incident occurred at a local Amoco gas station, where officers and agents had converged to confront a suspect.
As law enforcement attempted to arrest the man, he
produced a. 357-caliber handgun and opened fire. Captain Grass was struck in the head by a bullet and was transported to a hospital in Indianapolis, where he succumbed to his injuries about an hour later. He left behind a wife and two sons.
The suspect, identified as 45-year-old Marvin D. Castor, was apprehended at the scene. He was subsequently charged with murder. Following a trial, Castor was convicted of the murder of Captain Grass and was sentenced to death. However, in 1992, the Indiana Supreme Court, while affirming the conviction, overturned the death sentence. This led to a resentencing, and Castor was given a 60-year prison term.
Castor remained incarcerated for the crime. In June 2007, his application for executive clemency was denied by the governor. Ultimately, Castor died in prison in 2015.
