KANSAS CITY, Mo. -- Dennis Sharkey was shot and killed on I-29 Friday night driving his white Chevy Spark near the NW 72nd Street offramp. Platte County investigators say they need your help finding whoever may have killed Sharkey. The sports reporter's family is repeating that call for help, with no one in custody. One day after his 50th Birthday, friends and family say Sharkey was where you'd find him most Friday nights, traveling to or from a high school sporting event. In this case, he was returning from covering girls high school wrestling in Faucett, Missouri for the Platte County Citizen. "It's not going to be the same, especially north of the river. He really cared about those kids he reported about," friend Olivia Gaw said. 1 dead, 1 injured in Northland shooting late Tuesday afternoon Sharkey got on I-29 heading south about 6:30 p.m. Friday, but according to authorities he and another drive stopped on the side of the interstate near NW 72nd Street in Platte County a little before 7 p.m. "The other guy got out and pointed a gun and Sharkey took off and was shot," friend Richard Brand said. Loved ones say the sports reporter loved the Kansas City Chiefs and will be honored at a tailgate before Saturday's playoff game against the Houston Texans. "When we drafted Patrick Mahomes, he called my husband and said, 'this is the beginning of a dynasty, you just wait,'" Gaw recalled. They say he also cared for his community, reporting on more than just sports during his journalism career. "He was a true reporter. He spoke the truth. He didn't care, he did his job well," Sadie Grigsby said. Now they are hoping the big news tip he was always seeking, is one that will lead authorities to his killer. Authorities increased the reward for information to the TIPS Hotline leading to an arrest from $2,000 to $25,000.
