A tragic mix-up at the Mecklenburg County Detention Center has claimed the life of Miguel Gonzalez Rosales, a man awaiting trial on murder charges. In a stark failure of protocol, Rosales was pronounced dead after being mistakenly given a high dose of methadone, a powerful opioid, which was meant for another inmate. The medical examiner's report outlined this medication error as the cause of death, revealing he had been given 110 milligrams of methadone— a substance he was not prescribed and to which he had no tolerance.
According to Queen City News, "toxicology results confirmed the presence of methadone in his blood and liver." Methadone is used to treat severe pain or opioid addiction, but for someone without a history of opioid use, such as Rosales, the medical examiner concluded the dose "would markedly increase the risk of sudden death due to respiratory and central nervous system depression."
The mix-up occurred on August 6, 2025, when corrections staff discovered Rosales unresponsive in his cell. Despite attempted resuscitation, he was declared dead at the jail. As reported by Channel 9, "Gonzalez-Rasalas was charged with killing a woman, who was his neighbor in 2023." He had been incarcerated since April 9, 2023, after Laura Miller’s gruesome murder at an east Charlotte apartment complex.
Investigations into the incident are underway by multiple agencies including the State Bureau of Investigations and the MCSO's Office of Professional Compliance. The Mecklenburg County Sheriff's Office, adhering to policy during these investigations, has refrained from commenting so as to avoid influencing the outcome. However, they have emphasized that they are, according to Queen City News, conducting "multiple and parallel investigations into the nature and circumstances of the event."
Meanwhile, WCNC reported that the autopsy has categorized Rosales' death as an accident. No comments have yet been made on whether the medication error will result in any disciplinary action against staff members.
