14-Year-Old Boy Among Five Killed in Tragic Turlock Intersection Crash in Stanislaus County

A devastating crash in Stanislaus County has claimed the lives of four members of the Lourenco family and the driver of another vehicle. The incident occurred on Sunday morning when the family was driving to church. At approximately 9:25 a.m., their Jeep was struck by a speeding sedan at the intersection of Greenway Avenue and Highway 165 in the Turlock area, according to the California Highway Patrol.

Daniel Lourenco, 44, and his wife, Jennifer Lourenco, 45, were pronounced dead at the scene. Their 16-year-old daughter, Madelynn, succumbed to her injuries shortly after arriving at the hospital. On Friday, the family confirmed that their 14-year-old son, Matthew, also died after fighting for his life for several days.

The driver of the sedan, identified as 22-year-old Uriel Guizar Negrete, was also killed in the crash. Investigators noted that everyone in the Lourenco family’s vehicle had been wearing seat belts, while Negrete had not.

A 19-year-old teenager from the Lourenco family survived the collision and remains hospitalized in the intensive care unit.

Jennifer Lourenco was a beloved teacher at Sinclear Elementary School, where she had been named Teacher of the Year for 2023-2024. In a statement, the Ceres Unified School District described her as a “gifted and dedicated educator” who was cherished by colleagues and students. Both Madelynn and Matthew Lourenco were students at Pittman High School, where their deaths have deeply affected the school community.

The intersection where the crash occurred has been described by residents as a dangerous area prone to accidents. Since January 2023, six crashes have been reported at the intersection of Greenway Avenue and Highway 165, three of which resulted in injuries.

The tragedy has renewed community calls for safety improvements at the intersection as residents mourn the lives lost in the crash. The investigation into the incident remains ongoing.

Driver Dies After Street Sweeper Hits Big Rig on Manteca Off-Ramp

By Frank Penney • July 2, 2025

Tragedy struck Monday morning in Manteca when a street sweeper collided with a parked big rig, leading to the death of one person, according to the California Highway Patrol. The accident happened around 8:27 a.m. on the southbound off-ramp from Highway 99 to Lathrop Road. Authorities reported that the big rig was stopped on the right shoulder, safely out of the traffic lanes. For reasons still under investigation, a street sweeper traveling at approximately 40 miles per hour struck the rear of the big rig. The driver of the street sweeper was not wearing a seatbelt at the time of the crash and suffered critical injuries. Emergency responders transported the driver to a nearby hospital, but despite efforts to save their life, the driver was later pronounced dead. The CHP did not release the driver’s identity. The big rig had a passenger onboard who fortunately was not injured. At this time, the CHP does not believe that drugs or alcohol played a role in the collision.

Driver Seriously Injured in Highway 99 Crash Near Fresno Street

By Frank Penney • June 11, 2025

A driver was seriously injured Saturday evening in a crash on Highway 99 near Fresno Street, according to the California Highway Patrol. The incident occurred on the southbound shoulder of the highway, where a commercial big rig had pulled over due to mechanical issues. As the truck sat stopped on the shoulder, a Ford Taurus traveling at high speed veered onto the same shoulder and slammed into the back of the trailer. Authorities say the Taurus appeared to be driving recklessly before the collision. The impact left the car heavily damaged, and the driver—who was not wearing a seatbelt—was rushed to a local hospital with major injuries. “Our hearts go out to the injured driver,” the CHP said in a statement. “This incident serves as a stark reminder that excessive speed and reckless behavior can have devastating consequences.” The CHP is using the crash as an opportunity to remind all motorists to drive responsibly, follow traffic laws, and always wear a seatbelt.
