The family of Derimán Alemán, a 29-year-old inmate who died on September 23, 2025, at the Hospital Insular de Gran Canaria after being transferred from Juan Grande prison (Las Palmas II), has reported potential negligence. According to his sister, Nisa Alemán, if an ambulance had been called, her brother would be alive. The inmate complained of recurring pains in various parts of his body and suffered from a severe mental illness, according to the family.
Eight months after the death, the Institute of Legal Medicine (IML) of Las Palmas has submitted six questions to the prison's health service for the court, pointing out possible inconsistencies in the clinical history compiled. Doubts arise from contradictory notes regarding the administration of Akineton and a drug test, as well as the timing of a medical report which, according to the IML, was made when the inmate had already died and was outside the facility.
The IML questions why the transfer to the hospital was carried out in a Guardia Civil van and not by ambulance, given that the inmate was admitted with respiratory failure. The response from the prison's medical service, signed by the deputy medical director and sent by the management led by Jorge Garlito García, attributes the late notation to workload overload and states that Akineton was administered only once. They maintain that no signs of severity were observed and that the inmate 'walked normally on his own,' attributing his condition to a possible viral process.
The family, through their lawyer, has described these explanations as 'false' and has filed a petition with the court. They argue that security camera footage contradicts the official version, showing a Derimán Alemán with extreme difficulty walking, being assisted by other inmates, and transferred in a wheelchair to the Guardia Civil van. The defense describes a 'serious condition' and 'difficulty walking'.
The lawyer also highlights the difference between a 'visit to the emergency room' and an 'urgent departure,' noted in the prison's own clinical record at 11:04 AM, while the subsequent report was made outside the facility. The family insists that the prisoner spent his final hours in a 'critical health condition,' unable to stand, and that the prison's version is contrary to the 'material truth of the facts'.
Magistrate Lorena Quíles Vallejo, from the Court of Instance of San Bartolomé de Tirajana, has ordered the prison center to submit all the inmate's medical evolution sheets to the IML to clarify the facts and assess possible negligence by the center's healthcare staff. The preliminary autopsy points to acute lung edema, pending toxicological analyses.
The family maintains that Derimán Alemán suffered from schizophrenia, bipolar disorder, and borderline personality disorder. The complaint filed is for a possible charge of reckless homicide and omission of the duty of care. The judicial proceedings remain open with no formal charges.
The family has called for a peaceful demonstration on Monday, June 8, in front of Juan Grande prison, alongside Ángeles Santana, sister of another inmate who died in the same center in 2023. They are demanding a review of prison health and psychological protocols under the slogan 'Truth is not locked up'.
