A 79-year-old woman has died after a two-vehicle collision at a busy Mesa intersection when investigators say a truck failed to stop at a red light and struck another car from behind. Police identified the victim as Karen Kae and said she was fatally injured in the crash, which occurred on the morning of June 26 at Recker Road and Main Street.

The Mesa intersection where police say a two‑vehicle, red‑light crash occurred; traffic lights and nearby businesses are visible at the scene.
Mesa police have described the collision as the result of a vehicle running a red light. Early accounts released by investigators indicate that a truck continued through the intersection against a red signal and struck the rear of another vehicle. Emergency responders arrived at the scene and the occupant of the struck vehicle, later identified as Kae, suffered fatal injuries. Police said the truck driver was subsequently taken into custody and faces a manslaughter charge in connection with the death.
Authorities also indicated the driver of the truck was suspected of being under the influence at the time of the collision, a factor investigators are examining as part of the ongoing inquiry. The investigation into the causes and contributing circumstances of the crash remains active. Officers at the scene collected evidence, and investigators are working to confirm details such as vehicle speeds, traffic-signal timing and witness statements that could clarify the sequence of events that led to the fatal impact.

The arrest on a manslaughter charge followed the investigation conducted at the scene. Police did not immediately release extensive details about the condition of other vehicle occupants or whether anyone else was transported to a hospital. The department warned that charges and the investigation are ongoing, and that additional information will be released when it is verified and cleared for public disclosure.
The deadly collision has prompted renewed attention to intersection safety across the region. Statewide traffic figures cited in recent reports show that, as of 2024, about 1,307 people were killed on Arizona roadways, a number that represented a slight decline from a previous reporting period. Those same reports have highlighted that alcohol impairment and excessive speed continue to be among the leading contributing factors in fatal crashes. Local officials and traffic-safety advocates frequently point to red-light running and impaired driving as persistent dangers at intersections where signals and heavy traffic converge.
Attorneys who handle crash and wrongful-death matters said families affected by such collisions often have legal options pending the results of criminal and police investigations. An attorney at a local law firm described independent investigations that may be conducted on behalf of victims’ families, noting that such work often goes beyond the initial police inquiry. "An independent investigation focuses on what you need for your case. That might include interviewing additional witnesses and taking photographs and measurements, sometimes to dispute an inaccurate police report," said Cristina Perez Hesano, an attorney at Perez Law Group.
Legal representatives also outlined the types of damages families may pursue in civil actions related to fatal collisions. Those potential claims typically include recovery for funeral and burial costs, medical expenses associated with the injury that led to death, lost wages and loss of future earning capacity, as well as compensation for loss of companionship and support. "Victims have the right to be paid not only for the money they lost but also for the pain they have suffered," said Gabriel Miller, an attorney at Perez Law Group. In addition, some advocates note that dealing with insurers and other parties can require experienced legal counsel to protect a family’s rights and ensure claims are properly presented and pursued.
Mesa police continue to investigate the circumstances of the crash that claimed Kae’s life. The identity of the arrested driver has been confirmed by law enforcement as the person taken into custody at the scene, and the manslaughter charge reflects the seriousness of the allegations. The department has urged anyone with information or dashcam footage from the intersection around the time of the crash to contact investigators. Meanwhile, attorneys and family advocates pointed to the various civil remedies that may be available to survivors and relatives as criminal proceedings and a full traffic-collision investigation move forward.
For those seeking legal guidance related to the collision, attorneys at Perez Law Group were listed as a contact option in public materials connected to coverage of the crash. The firm has been referenced by family members and others in past cases handled in the area and may be reached at the phone number provided in public notices related to this incident. Investigators emphasized that their work is continuing and asked for patience while evidence is gathered and reviewed prior to further public updates regarding charges or a full reconstruction of the crash.
Mesa police identified the truck driver as 39-year-old Caesar Miguel Zalava-Soso, who faces the manslaughter charge after allegedly running the red light while impaired. In response to the crash, the department is intensifying enforcement against red-light runners and aggressive drivers at city intersections, according to ABC15 and Det. Robert Katz.
Mesa police told local reporters the collision occurred at about 9:30 a.m. on June 26.
ABC15 and city officials said Mesa officers have issued more than 100 additional citations and warnings for red‑light running and other aggressive driving over the past three months compared with the same period last year as part of stepped‑up enforcement.
An online obituary lists the victim’s full name as Karen Sue Kae and gives her date of death as June 26, 2026.
