In one investigation involving Julián Álvarez Guardia, his sister submitted handwritten letters to the Prosecutor’s Office to document the victim’s emotional distress and his relationship with the sole suspect in custody, Victoria Cantero. The documents include a letter where the victim expressed, “Today I woke up with anxiety, depression because of the situation I am going through... I am isolating myself from everything.” In San Juan, a march was held to demand justice for Gemma Giselle Álvarez, a healthcare worker killed in a femicide. The suspect, Matías Exequiel Marín, was apprehended after being a fugitive and has been placed in preventive detention for one year. Protesters and family members criticized the judicial protection system, noting that the victim had previously reported stalking and harassment. In Alvear, investigators have reclassified the death of 16-year-old Cecilia Lazcano from a suspected suicide to a femicide. Authorities are targeting a 16-year-old male classmate as the perpetrator, who allegedly acted at the request of his girlfriend. The reclassification follows forensic findings regarding a fatal trachea wound and the review of security footage. ## Timeline ### 2026-08-12: Zapopan real estate advisors disappear in Jalisco Two real estate advisors, Ricardo Cabezas Talavera and Octavio Haro Cachua, have disappeared in Zapopan, Jalisco, within 12 days, sparking concern in the local business sector. 14 sources. https://clstr.news/cluster/argentina-investigates-two-separate-cases-of-violent-death ### 2026-08-10: Criminal investigations reported in Argentina and El Salvador Authorities in Argentina are investigating a 16-year-old for the femicide of Cecilia Lazcano, while in El Salvador, an 11-year-old girl drowned in the Bandera River. 3 sources. https://clstr.news/cluster/criminal-investigations-reported-in-argentina-and-el-salvador --- Cite as: Violent death and femicide investigations in Argentina.
