AI-generated summary
A 79-year-old man died from complications of multiple injuries sustained when his wife's vehicle was struck by an unmarked police car at an intersection. The police vehicle was engaged in a pursuit of a stolen vehicle and approached a red traffic light at excessive speed (64 km/h at final 0.5 seconds before impact). The driver entered the intersection against the red light, believing the other vehicle would give way based on his mistaken assumption. The collision caused serious injuries including spinal fractures, rib fractures and sternal fractures. The patient underwent surgery but subsequently developed bronchopneumonia, likely related to immobility from his injuries, which contributed to his death on 18 May 2018. The pursuit was initiated appropriately but the secondary pursuit unit's approach speed was excessive for the circumstances and the driver failed to activate sirens as required.
