A man accused of shooting an off-duty Mississippi Highway Patrol trooper will spend at least 30 years in prison after pleading guilty to the killing.

Damion Whittley, 27, pleaded guilty to depraved heart murder.

Depraved-heart murder, also known as depraved-indifference murder, is a type of murder where an individual acts with a “depraved indifference” to human life and where such act results in a death, despite that individual not explicitly intending to kill.

Whittley received the maximum sentence of 40 years, 30 of which without the possibility of parole, according to a news release from District Attorney Daniella M. Shorter.

On August 7, 2020, the body of Troy Morris was found on the side of US 61 South of Fayette, Mississippi.

Morris, an off-duty Mississippi Highway Patrolman, had been working his part-time job with the United States Postal Service at the time of his murder.

“Evidence recovered at the scene and testimony provided by eyewitnesses established Whittley as the perpetrator,” the news release said. “The defendant pleaded guilty to depraved heart murder and received the maximum sentence afforded by law.

District Attorney Shorter said this conviction and sentence were warranted by the facts and is part of her pledge to deal with crimes of a violent nature in a harsh straightforward manner.

Morris, of Natchez, was a 27-year veteran of MHP, authorities said.
