The tragic story of Maria Munoz will be shown in the first episode of Married to Evil on Investigation Discovery which will air on Sunday, August 25, 2024. The episode titled A Deadly Dose will show the real-life story of deceit and betrayal within a marriage that leads to dire consequences.

The show investigates cases where one partner’s malevolence results in devastating outcomes providing insights into the darker aspects of supposed marital bliss.

Maria Munoz was a 31-year-old mother who was murdered by her husband Joel Pellot in September 2020 in Laredo, Texas. The case was initially reported as a suicide by pill overdose but further investigation revealed a more sinister reality. Joel was a nurse anesthetist who used his medical access to administer a fatal combination of drugs including propofol to Maria which led to her death.

The act was meticulously planned to look like an overdose which was diverging from the truth uncovered by police through suspicious items found at their home and discrepancies in Joel’s account of the events. Joel Pellot was later convicted of murder and sentenced to life imprisonment.

1) Pre-meditated murder disguised as suicide

Maria Munoz’s death was initially reported as a suicide by her husband Joel Pellot who called 911, claiming she might have overdosed on pills. The crime scene presented initially suggested an overdose of pills and apparent medical distress.

But the investigation later uncovered that Joel had meticulously planned to make her death look like a suicide. He used his medical knowledge as a nurse anesthetist to administer a lethal combination of drugs not found in her prescribed medication which turned a supposed suicide into a clear case of pre-meditated murder that shows a calculated betrayal by someone trusted to protect her health and well-being.


2) Manipulation of medical expertise

Joel Pellot’s position as a nurse anesthetist was central to the execution of the murder. He had access to powerful surgical drugs like Propofol which is rarely used outside of controlled medical environments and cannot be administered without substantial medical knowledge.

Joel used this access to administer a deadly cocktail of Propofol along with other drugs such as morphine and ketamine which were found in Maria’s system. His professional expertise enabled him to inject these substances in a way that initially misled first responders and investigators that obscured the true nature of her death.


3) The discovery of incriminating physical evidence

The Physical evidence at the home raised immediate suspicions among the first responders. Notably, a syringe wrapper and a needle catheter were found on the premises which were inconsistent with an overdose by pill ingestion. These items suggested the involvement of injected substances.

Further scrutiny led to the discovery of the actual drugs used in the murder, none of which were substances that Maria Munoz had been prescribed for any medical condition. This contradicted Joel’s initial story and pointed towards foul play majorly altering the direction of the investigation.


4) Joel Pellot’s behavior and contradictory statements

Joel Pellot’s behavior on the night of the incident and during the initial investigations raised doubts. Despite his calm demeanor when calling 911 his excessive sweating and nervous behavior when questioned by police were noted as suspicious.

Furthermore, his conflicting statements about the events leading up to Maria Munoz’s unresponsiveness did not align with the physical evidence. His claim that Maria Munoz had been depressed and potentially suicidal contradicted known facts about her mental state as revealed by close friends and her own journal entries which showed no indication of suicidal thoughts.


5) Autopsy and toxicology reports

The autopsy and subsequent toxicology reports were crucial in shifting the case from a suspected suicide to murder. The autopsy revealed no pill residue in Maria Munoz’s stomach but did find a tiny puncture mark on her right elbow crease that suggested an injection site.

The toxicology report identified several drugs typically used in surgery in her system none of which she had access to or prescriptions for. These findings undermined the initial suicide theory and showed a premeditated use of Joel’s medical access and knowledge to commit murder framing it as a self-inflicted overdose.


The episode will air on Sunday, August 25, 2024, on Investigation Discovery.
