KANSAS CITY, Mo. -- A Kansas City police officer is in critical condition after being involved in a crash Wednesday morning. According to KCPD, at about 9:40 a.m., a motorcycle traffic officer was hit near the intersection of Gregory Boulevard and Troost Avenue. Police investigating deadly overnight I-70 crash in Kansas City Preliminary investigation revealed that the officer was driving northbound on a motorcycle when an SUV traveling in the opposite direction turned in front of the bike, causing the crash. Emergency responders and KCPD arrived at the scene and took the officer to a hospital where he was said to be in critical condition with life-threatening injuries. However, just after 2 p.m. Wednesday, the officer was upgraded to "stable condition," according to the police department. KCPD said the other driver involved in the crash remained at the scene and cooperated with investigators. Officers were initially alerted about the crash after nearby bystanders rushed to the officer's aid. Investigation revealed that one person pushed the emergency button on the officer's police radio, alerting law enforcement as another person provided medical aid and CPR. "He actually pressed that, which automatically goes to our dispatcher, and our dispatcher tried reaching the officer on the radio, and he did not respond, so the dispatcher immediately dropped to assist the officer," KCPD Sergeant Jonathan Rivers said in a news conference Wednesday with reporters. "At the same time that was going on, our real-time crime center informed the dispatcher that we had an officer down." Sergeant Rivers said it was a business owner who pressed the emergency button. He would not name the business owner or the driver of the silver Toyota that struck the KCPD motorcyclist. The police department said, "Because of those citizen’s quick thinking we were alerted to the emergency." Police investigating deadly overnight I-70 crash in Kansas City KCPD Chief Stacey Graves came to the scene Wednesday, too. She says the officer hit is tenured, but she wouldn't release his name. She did say the radios the officers wear have GPS technology, and the citizen who pushed that button on the officer, may be the reason the officer's condition has actually gotten better. "It's a radio like Sergeant Rivers is wearing right now," Chief Graves said, standing right next to Sergeant Rivers. "This red button is our emergency button that immediately leaves an open line and overtakes all other radio traffic at that time to where somebody has an emergency, they have full access to the radio traffic at that time." The unnamed business owner wasn't the only one who helped out Wednesday. "I was standing up front, and I heard a car crash," Soil Service Garden Center employee Brian Daniels said in an interview with reporters. "Then I looked outside and saw that there was a police officer laying in the middle of the road. So, I ran up, yelled, told everybody to call 9-1-1. It was pretty gruesome. I yelled and told everybody to flip him on his side because he started choking." Chief Graves hugged Daniels after she talked to reporters Wednesday, thanking him for being one of a few who helped her officer. Traffic Investigations and Accident Investigation Sections are investigating the crash.
