A Mississippi registered nurse is facing charges of depraved heart murder, according to the state’s attorney general. April Renae Grissom, 28, is accused of turning off machines that were helping to keep a 77-year-old patient alive at the medical facility where she worked.

Attorney General Jim Hood said in a news release that Grissom turned herself in Wednesday, after she was indicted by a Lamar County grand jury. Under Mississippi law, depraved heart murder is an action that demonstrates a “callous disregard for human life” and results in death. If convicted, Grissom could face up to life in prison.

Grissom was booked at the county jail under $10,000 bond.

According to court documents provided to Life Matters Media: While working as a registered nurse at Wesley Medical Center on March 26, Grissom entered the room of the patient without medical orders or “clinical inclination” and turned off the dialysis machine, the amiodarone drip, and decreased the norepinephrine and phynelephrin drips causing death. The victim’s name was redacted.

“This is a matter that involves an individual who was an employee of Wesley Medical Center, but has not worked at the hospital since April 2013. The hospital has cooperated with local law enforcement in their investigation,” said Wesley Medical Center in a statement to LMM.

Prosecutors are seeking an enhanced penalty due to the victim’s age and impairments. The trial has been set for September 16 to 18 in Lamar County Circuit Court, according to the attorney general’s office. Judge Mozingo will hear the case.
