New footage released by Univision reveals key moments from the Hialeah Police investigation into the tragic murder of 39-year-old Irina García, who was fatally stabbed in her apartment on the night of October 12, 2023. The primary suspect in this heartbreaking crime is her 13-year-old son, Derek Rosa.
Among the videos, one stands out, capturing the arrival of Isabel Acosta, Irina's mother and Derek's grandmother, at the crime scene. Unaware of the full extent of the tragedy, she came with another grandson, confused and seeking answers. However, the most compelling footage is a 13-minute interview in which a homicide detective questions Isabel inside a vehicle. The video captures her growing distress as she begins to suspect the worst about her daughter.
The Agonizing Discovery
During the interview, Isabel, visibly anxious, repeatedly inquired about her grandson. The detective's vague responses only heightened her confusion and fear. Isabel recounted how her son, Irán García, a truck driver, had urgently called her to rush to Irina's home. He explained that Frank Ramos, Irina's partner, was alarmed after seeing police arrive and arrest Derek through the apartment's Ring camera.
Accompanied by another grandson living with her, Isabel hurried to the scene, only to encounter a bewildering array of police officers and scant information. "They don't tell me anything," she lamented, clearly distraught. An officer held baby Ashley, who had been born just 14 days earlier, on September 29.
A Family's Bond
Discussing the relationship between Irina and Frank Ramos, Isabel noted they had been together for three to four years, although not married. In response to the detective's questions, she described Derek as "a calm child," asserting he had no history of mental or medical issues. "That child is an angel," she declared confidently. She denied any problems between Derek and his mother, emphasizing their mutual respect.
"No, my dear, that child respects her. She is a very proper person, just like his father," Isabel remarked, referring to Derek's father, who is a police officer. "Derek is just like his father. They are like angels," she insisted, her anxiety over the mystery surrounding the night growing.
Isabel shared that Derek was delighted with his new baby sister, Ashley. She recounted her visit to the home on October 11, spending time with the newborn and Derek and helping Irina after her cesarean section. "Everything was fine last night. Everything was perfect," she affirmed.
The Unanswered Call
Isabel attempted to reach Irina after receiving a call from her son around 11:47 p.m. on October 12, but Irina did not answer. This was confirmed by the detective's review of the phone records. As the interview concluded, the detective inquired why Frank Ramos had not contacted Isabel directly to warn her of the situation, instead relying on Irán. "I don't know," Isabel replied, visibly shaken.
Emotionally overwhelmed, Isabel ultimately voiced her deepest fear: "What happened to my daughter, huh? [...] Oh, my God, I think I no longer have a daughter. She is not alive," prompting the detective to end the questioning.
The trial for Derek Rosa, accused of stabbing his mother over 40 times on the night of October 12, 2023, has yet to be scheduled. Since the tragic event, Isabel Acosta has pleaded for mercy for her grandson, staunchly defending him to both authorities and the media.
