The Netflix series “I’m a Killer” follows Logansport’s Rex Groves, who was convicted of stabbing his grandmother to death.

The story of convicted Logansport killer Rex Groves is one of six new cases examined in the new season of the hit Netflix docuseries.

Groves, 46, was convicted of killing his grandmother, Mary Ann Jean Groves, in December 2009. His story is told in the fifth episode of the fifth season of the series “I Am a Killer,” which was released on the platform on October 16.

The episode focuses on the alleged abuse he suffered as a child, his mental state at the time of the murder, and the assessment of his mental competency during his trial. The episode also discusses his likely upcoming release in 2029, when he will be eligible for parole.

Groves was 32 when he accepted a plea agreement that said he would serve 46 years in the Department of Corrections, followed by four years of probation. In court, he admitted that on December 10, 2007, he had a disagreement with his 84-year-old grandmother. He pleaded guilty but mentally ill to murder, which is a Class A felony and carries a maximum penalty of 65 years in prison. He will be eligible for release after serving half of his sentence pending completion of a psychiatric evaluation.

The series details Groves, who was born and raised in Logansport and is now incarcerated at the Putnamville Correctional Facility. He talks about his upbringing, alleged abuse, mental health struggles as a teenager and his memories of the night of the murder and its aftermath.

The series also features a woman named Courtney, believed to be his niece, and his brother Doug Groves. The 46-minute episode also featured appearances from Dr. Don Olive, who was appointed by the Cass County Superior Court to undergo a competency examination and insanity evaluation, and attorney Bradley A. Rozzi, who was assigned to represent Groves in the case.

Katherine Collins, a former Logansport Police Department detective who conducted the first Cass County Jail interview with Groves after his arrest, watched clips of the video and discussed the case.

Groves was initially diagnosed with paranoid schizophrenia during a preliminary examination, but a second examination conducted by Olive concluded that he did have any mental illness that could support a claim of insanity.
