Bleeding control attempted in the roadway, all westbound lanes closed, extrication called, Captain Gravel rolling in
At 12:32 the Amherst-Clarence trunk went sharply quiet for one transmission and then loud for the next. "Speed Instruct United on the 290," a unit broadcast, and seconds later the answer came back over the radio at a register no scanner listener mishears: “Radio, semi-AMS — AMS is coming hot”. The transmission that followed gave the day its center of gravity — “My radio driver is severely hurt, still breathing, not responding” — a description coming from an officer who was on scene early enough to be the one putting hands on the patient.
Amherst Fire opened the formal box at 12:33: I-290 westbound at the I-990 interchange, one patient severely injured, extrication possibly required. Within minutes the closure footprint expanded — the center and right shoulder of 290 West were called shut, and an Amherst PD unit asked for help slowing traffic back at the Maple Road overpass to keep the secondary-crash risk down. North Bailey 9 responded under fire, with the call routed to operations channel two so the fire ground could work clean. By 12:36 the on-scene officer was relaying that there was still a pulse and that he was “attempting to try to stop the uncontrolled bleeding right now”; Twin City 223 reported on location seconds later.
Command stood up fast. The lieutenant was notified, Captain Gravel was logged en route, and Car 22 picked up the desk so 23 could move forward. Heavier units cycled in from North Bailey, with the incident commander placing the operation on Channel 2 to keep the dispatch frequency open for everything else still going on in Amherst. The injured driver was transported and the closure was eventually backed off through the afternoon, but the radio carried, for several minutes around 12:36, the unmistakable sound of an officer keeping someone alive with his hands while waiting for the ambulance to arrive.
