In the first five days of October, seven homicides were recorded in Hermosillo — including a decapitation case that shocked the city. The alarming start to October follows what authorities describe as the most violent month of the year so far, with 12 murders in September, according to official figures from Seguridad Pública de Hermosillo.
However, it should be noted that the murders occurred around various parts of the city with none near the downtown tourism district.
Timeline of the October Killings
The wave of violence began on Thursday, October 2, with two shootings occurring just one hour apart.
- The first took place at 12:40 a.m. in the Las Lomas neighborhood, where a man was fatally shot at the intersection of Real del Parque and Paseo Las Lomas.
- The second incident followed at 1:40 a.m., near Rinconada de la Cruz, where another man was killed on Irrigación Final Poniente and Jorge Valencia Jullerat.
On Friday, October 3, violence intensified:
- At 5:40 p.m., in Colonia Adolfo López Mateos, a third victim was shot and killed on Dalia and Palma streets.
- Later that evening, a fourth murder occurred in Colonia López Portillo, at Sinoquipe and Guadalupe Victoria.
- At 9:33 p.m., authorities discovered a headless body inside a burned vehicle in Colonia Peredas.
- By 11:00 p.m., a human head was found in Colonia Villa de Seris, at No Reelección and Comonfort. The Fiscalía General de Justicia del Estado is investigating whether the two discoveries are connected.
On Saturday, October 4, two more killings were reported:
- At 3:12 a.m., a man was shot dead at Mendoza and Lázaro Cárdenas in Colonia Sahuaro.
- At 6:00 a.m., another victim was found murdered in Cerrada Guadalupe de Villas del Sur.
Rising Violence Through 2025
The ongoing investigations underscore a troubling trend in Hermosillo. Official data show that October’s first week already surpasses the monthly totals of several previous months. The city’s homicide numbers this year are as follows:
| Month | Homicides |
| January | 5 |
| February | 4 |
| March | 8 |
| April | 5 |
| May | 11 |
| June | 10 |
| July | 8 |
| August | 8 |
| September | 12 |
While authorities have not released official motives for the killings, the pattern reflects persistent organized crime activity and violent disputes that continue to threaten public safety in the Sonoran capital.
